+# NxtPX4v2 Flight Controller
+
+The NxtPX4v2 is an open-source hardware designed and maintened by [HKUST UAV-Group](https://github.com/HKUST-Aerial-Robotics/Nxt-FC). And it is produced by [MicoAir Tech.](http://micoair.com/).
+
+## Features
+
+ - STM32H743 microcontroller
+ - BMI088+BMI088(DUAL) IMU
+ - SPL06 barometer
+ - 12V 2.5A BEC; 5V 2.5A BEC
+ - SDCard
+- 7x UART
+- 8x PWM
+- 1x I2C
+- 1x SPI
+- 1x SWD
+
+## UART Mapping
+
+ - SERIAL0 -> USB
+ - SERIAL1 -> UART2 (DMA-enabled)
+ - SERIAL2 -> UART4 (DMA-enabled)
+ - SERIAL3 -> UART1 (GPS, DMA-enabled)
+ - SERIAL4 -> UART3 (VTX-HD, DMA-enabled)
+ - SERIAL5 -> UART7 (ESC Telemetry, DMA-enabled)
+ - SERIAL6 -> UART5 (RCIN, DMA-enabled)
+ - SERIAL7 -> UART8 (DMA-enabled)
+
+## RC Input
+
+The default RC input is configured on the UART5_RX inverted from the SBUS pin. Other RC  protocols  should be applied at other UART port such as UART2, UART4 or UART8, and set the protocol to receive RC data: `SERIALn_PROTOCOL=23` and change SERIAL6 _Protocol to something other than '23'
+
+## VTX Support
+
+The SH1.0-6P connector supports a DJI O3 Air Unit connection. Pin 1 of the connector is 12v so be careful not to connect this to a peripheral requiring 5v.
+
+## PWM Output
+
+The NxtPX4v2 supports up to 8 PWM outputs. All channels support bi-directional DShot.
+
+PWM outputs are grouped and every group must use the same output protocol:
+
+1, 2, 3, 4 are Group1;
+
+5, 6 are Group 2;
+
+7, 8 are Group 3;
+
+## Battery Monitoring
+
+The board has a internal voltage sensor and connections on the ESC connector for an external current sensor input.
+The voltage sensor can handle up to 6S LiPo batteries.
+
+The default battery parameters are:
+
+ - BATT_MONITOR 4
+ - BATT_VOLT_PIN 4
+ - BATT_CURR_PIN 8
+ - BATT_VOLT_MULT 10.2
+ - BATT_CURR_SCALE 20.4
+
+## Compass
+
+The NxtPX4v2 does not have a built-in compass, but you can attach an external compass using I2C on the SDA and SCL connector.
+
+## GPIOs
+
+The remaining 3 outputs (labelled AUX1 to AUX3) are the "auxiliary" outputs. These are directly attached to the STM32H743.
+
+The numbering of the GPIOs for PIN variables in ardupilot is:
+
+ - AUX1 - PA4 - 81
+ - AUX2 - PC1 - 82
+ - AUX3 - PC0 - 83
+
+## Physical
+
+ - Mounting: 20 x 20mm, Φ3mm
+- Dimensions: 27 x 32 x 8 mm
+- Weight: 6.5g
+
+## Ports Connector

+
+## Loading Firmware
+
+Initial firmware load can be done with DFU by plugging in USB with the bootloader button pressed. Then you should load the "with_bl.hex" firmware, using your favorite DFU loading tool.
+
+Once the initial firmware is loaded you can update the firmware using any ArduPilot ground station software. Updates should be done with the "*.apj" firmware files.
