LCD dashboard (original by Gamadril)
Fully assembled, tested and working 30 pin SMD version, manufactured and pre-assembled by https://www.pcbway.com
Fully assembled, tested and working 30 pin thru hole version
Compact version for excavator (IBUS & sound only, supplied by 6V BEC)
- Unique vehicle mass inertia simulation (connect your crawler type ESC to pin 33). Throttle output is altered during shifting of a mechanical 3 speed transmission for smooth shifting, gear protection and realistic sound. Works just fine with TAMIYA 3 speed transmissions. Should work as well with crawler 2 speed transmissions. The ESC is controlled by a state machine with the following states: driving forward & reverse (varible acceleration, depending on throttle position), neutral, braking forward & reverse (variable deceleration with fine granularity, according to "reverse throttle" position). It also allows to control the brake lights, the brake sound, the reversing light & the reversing beep sound properly. Acceleration & deceleration (coasting & braking) are adjustable separately for each gear to ensure maximum realism.
- Unique "virtual clutch" allows to rev the engine below an adjustable ESC output speed. Above, the clutch engages and ensures, that the engine sound is in synch with the wheel RPM. Sounds and behaves just great in combination with a shifting transmission!
- Simulated automatic transmission with torque converter (if your vehicle does not have a real shifting transmission)
- Simulated double clutch transmission
- simulated, manually shifted 3 speed transmission (new in v5.5)
- Virtual, switchable neutral allows to rev the engine while standing still
- Jake brake (simulated pneumatic engine brake, mainly used in US trucks)
- Tracked mode (dual throttle input on CH2 & CH3, for tanks, diggers etc. No ESC control support in this mode. (New in v4.5)
- Tank cannon sound & flash (New in v4.6)
- Triggering multiple latching and non latching actions (sounds, lights) per analog channel, using the rcTrigger library (New in v4.7, still experimental)
- Many selectable sounds: engine cranking, engine idling, engine revving, turbo whining, diesel ignition "knock", wastegate valve, horns, sirens, reversing beep, air brake, parking brake, gear shifting etc.
- Realistic engine sound is mixed together on the fly from up to 4 sounds: engine idling, turbo, wastegate (all with variable sampling rate), Diesel ignition knock (fixed sampling rate, so it does not vary in pitch)
- Load (throttle position) dependent volume sounds: idle, rev, Diesel knock
- Engine RPM dependent volume sounds: turbo, wastegate
- Dozens of engine & other sounds included, you can also compose your own, using Audacity and bitlunis conversion tool (link above)
- Engine RPM range and inertia adjustable, volume of all sounds adjustable, engine sounds separatly for load and idling.
- Many other paramerets can be adjusted. All adjustments are easily accessible in "adjustmentsXyz.h"
- Sound files up to 22'050Hz, 8bit, mono can be used
- Compatible input signals: PWM, PPM, SBUS (inverted & non inverted signals), IBUS
- Works best with a PAM8403 amplifier module, connected to pin 25 & 26, via 10kOhm resistors & a 10kOhm potentiometer (see schematic below)
- The engine RPM is calculated according to RC signal input on pin 13 *** CAUTION, 3.3V max. on all pins! *** 330 Ohm resistors on all I/O pins recommended!
- Non linear throttle curves can be generated in "curves.h"
- Light effects: headlights (high & low beam), tail lights, brake lights, fog lights, roof lights, cab lights, reversing light, indicators (turn signals), hazard lights, blue light etc. (max. 12 outputs)
- Engine vibration simulation, using a shaker motor with excentric weight: Strong vibration while cranking, medium wlile idling, slight while revving
- Adjustable volume (via remote)
- Use an ESP32, CPU frequency must be set to 240MHz
- Eagle schematic & board file included. Pre made Gerber files allow you to order your board easily.
- included, easy to use .wav to .h sound file converter
- Channels can easily be assigned, using "remoteSetup.h"
- Pre made configuration profiles for Flysky FS-i6X and Arduino Mirco RC remote (new in v.5.5)
- Variable length for horn & siren, using loop area in sound files (new in v5.6)
- BUS decoder for steering servo and shifting servo (connect servos to CH1 & CH2) pins
- Trailer coupler (5th wheel) servo can be connected to the CH4 pins (not in PWM communication mode)
- TAMIYA trailer presence switch can be connected to pin 32 (depending on "#define THIRD_BRAKELIGHT" setting in "6_adjustmentsLights.h" tab)
- Support for non linear throttle and steering curves (for more accurate control around center position). Use "EXPONENTIAL_THROTTLE" & "EXPONENTIAL_STEERING" in "2_adjustmentsRemote.h"
- Support for HOBBYWING Quicrun Fusion Motor / ESC combo. Use "#define QUICRUN_FUSION" in "3_adjustmentsESC.h"
- Support for winch, connected to CH3 (BUS communication mode only). Use "#define MODE2_WINCH" in "7_adjustmentsServo.h" The mode 2 button is then used to switch between horn / siren sontrol and winch control via CH4. The winch is controlled by an old RC servo driver board. The speed and neutral settings are done using "CH3L", CH3C" and CH3R" positions.
- Support for LCD dashboard
- Support for 2812 Neopixel LED (GPIO0)
- Support for hydlaulic excavators (hydraulic pump, hydraulic flow, track rattling sounds). Use #define FLYSKY_FS_I6S_EXCAVATOR profile for remote
- ESP-NOW based 2.4 GHz wireless trailer control support
- An RZ7886 motor driver IC can be used instead of a standard crawler type RC ESC
- Battery low discharge protection options
- Switchable crawler mode (with just minimal virtual inertia)
- Wireless configuration website 192.168.4.1
- cornering lights (on the beacon outputs)
- Hazards switching on, if engine off in AUTO_LIGHTS mode
- Arduino IDE 1.8.7 or older is not supported and will cause compiler errors!
- The ESP32 does not work on macOS Big Sur 11.x, but this issue can be fixed easily as described here: Big Sur Fix (for v1.04)
- macOS Monterey 10.3 does not include Python 2 anymore. For Arduino IDE, you have to install Python 3 and to change the path in pPlatform.txt according to: https://forum.arduino.cc/t/mac-os-update-killed-esp32-sketch/969580/24
- import the WAV sound file you want in Audacity
- convert it to mono, if needed
- on the bottom left, select project frequency 22'050Hz
- search for a cyclic pattern in the idle sound (the amount of ignition pulses is usually the same as the cylinder number), cut the "idle" sample to exactly this length, have a close look at the zero crossings to avoid clicking noises. The loudest peak should always be at the end of the sample.
- do the same with the "rev" sound. It will be 2 - 4 times shorter than the "idle" sample, depending on the engine and rpm of the "rev" sample
- change the "Rate" (dropdown on the left of the sample) of the "rev" sample, until the length is the same as in the "idle" sample. This is very important!
- duplicate a part of the "rev" sample (the one with the original, unchanged "Rate" speed). This is the "knock" sample. Cut it to this max length: "Idle" length / number of cylinders / rpm range "MAX_RPM_PERCENTAGE" (usually 2 - 4 or 200 - 400%)
- adjust the volume of all samples, so that the entire dynamic range is used
- you may also want to apply high pass or low pass filters to fine tune the sound
- select > export audio > selected audio > WAV > 8-bit-PCM
- open the included "Audio2Header.html" converter in your browser. It is located in the "tools" folder
- adjust the export file format (no changes required)
- select the export file type, depending on the sound you are converting (idle, rev, horn etc.)
- open the wav file you want to convert
- a .h file is generated and downloaded
- move it to your "sketch/vehicles/sounds" directory
Include the new header file with your sound in your vehicle preset, adjust settings until you are happy:
- include this .h file in "Adjustments.h" > "yourVehiclePreset.h"
- knock sound settings:
- "dieselKnockInterval" = number of cylinders
- uncomment "V8" for V8 engines, R6 for inline 6 engines or "V2" for V2 (Harley) engines
- adjust "dieselKnockAdaptiveVolumePercentage" (how loud the "silent" knock pulses are compared with the loud ones), only active, if defined "V8", "R6" or "V2"
- play with the other volumes, start-, end- and switch-points until you are happy
- the "rev" sound is optional and only active, if "REV_SOUND" is defined (// removed)
- adjust the transition from the "idle" to the "rev" sound, using "revSwitchPoint", "idleEndPoint", "idleVolumeProportionPercentage". This step is very important and can make a huge difference!
- compile and upload the sketch in Arduino IDE
- the new sound should now be ready
- See hardware folder

- This device is not protected against wrong polarity!
- Always use series resistors for LED headers (except TAMIYA trailer header)
- Maximum input voltage on "Sig" pins = 3.3V (be careful with very old receivers, which may deliver 5V)
- It is recommended to use a fuse between your battery and the sound controller / ESC
- Use an Y-cable between your battery, your ESC and The "X1" terminal. Battery voltage range is 7 - 12.6V
- The ESP32 is not supplied through the "X1" terminal
- It can be supplied through the Micro USB header
- or through the +V and GND pin row on the top of the board (the voltage is usually coming from the BEC in your ESC, which needs to be connected to the "ESC" header)
- Connect a Hobbywing 1080 ESC to the ESC header (GND, V+ and Sig)
- Adjust the ESC parameters, using the programming card as described on the top of "Adjustments.h"
- I do not recommend any other ESC
- The ESC is controlled by the cound controller, rather than directly by the receiver. This allows to use the unique "virtual inertia" feature. NOTE: Use this feature at your own risk! I'm not responsible, if any damage is caused. It's running very stable and I never had an issue, but you never know.
- "escPulseSpan" can be used to limit the top speed of your vehicle. 500 = not limited, anything above 500 will limit the top speed
- Channel assignment according to "remoteSetup.h" and remoteSetup.xlsx", easily adjustable (new in v5.5). It is important to plug in the wires according to the channel assignment
- CH5 & 6 are coming in via the "35" & PPM" headers
- At least one CH needs to be connected, using a 3 pin wire, so that GND and V+ are connected as well (receiver supply)
- CH1 - 4 headers are pairs, wired in parallel. This allows to feed servo signals through, eliminating the need for Y-cables
- Note that you need to change the configuration as described below, if you want to use this wiring method
- Internal channel assignment as above
- Connect a 3 pin wire fom your receiver PPM header to the RX (changed in v5.5, was PPM) header on the sound controller (Sig, V+, GND)
- Note that you need to change the configuration as described below, if you want to use this wiring method
- 8 channels can be read in this mode
- Internal channel assignment as above
- Connect a 3 pin wire fom your receiver SBUS header to the SBUS header on the sound controller (Sig, V+, GND)
- The "Sig" pin on the SBUS header is 5V tolerant
- 13 channels can be read in this mode
- Internal channel assignment as above
- Connect a 3 pin wire fom your receiver IBUS header to the RX header on the sound controller (Sig, V+, GND)
- 13 channels can be read in this mode
- 4 or 8 ohms speakers are compatible
- You can use one or two speakers
- never use two speakers in parallel on a single header
- never use two headers in parallel to drive one speaker
- never connect capacitors to the speaker headers
- The LED need to be wired "common positive". This means, the long LED legs are all connected together and connect to the 5V rail, coming from the on board regulator
- All LED (except the ones, which are connected to the TAMIYA trailer connector) need a series resistor
- Calculate the reqired resistor according to: http://ledcalc.com (supply voltage = 5V)
- It is not recommended to wire LED in parallel, sharing the series resistor
- Support for WS2812 Neopixel LED (details and wiring see "6_adjustmentsLights.h")
- See "9_adjustmentsDashboard.h"
- The shaker is used for engine vibration simulation. The speed can be adjusted in the vehicle configuration and will vary depending on the engine state and rpm
- It needs to be connected to the "shaker" header and is supplied by the on board 5V regulator. The negative side is switched by the on board mosfet
- Please note, that the used mosfet needs to be a logic level type. Otherwise the shaker will not work!
- The motor should not draw more than about 300mA @ 5V. I'm using a shaker motor from GT Power.
It is intended for smaller scale vehicles like WPL

SBUS non standard signal (if your receiver sends a non-standard SBUS signal):
boolean sbusInverted = false; // false = wired to non standard (inverted) SBUS signal (for example from "Micro RC" receiver)

SBUS baudrate fine adjustment. 100000 ist standard. With some receivers, the indicators and other functions may be randomly triggered, because there are bit errors. This variable allows to fine adjust the baudrate to solve this problem.
uint32_t sbusBaud = 100000; // Standard is 100000. Try to lower it, if your channels are coming in unstable. Working range is about 96000 - 104000.
