Electronics (for dummies)

Don't have much experience with electronics? It's actually really simple!

Components

• LED-Array, Neopixel, 8x8 🢂
• ESP32 🢂
• Stepper Motor and Driver Board 🢂
• Female-Female Jumper Wire, 0.14 mm² 🢂
• Power cables for ESP32 - USB-microUSB 🢂

Connecting the electronics

• When using jumper wires you can avoid most of the soldering.

LED array - 3 wires

Connect everything - mind the right pins!

• The wires connect to the little trident which goes into the LED array
• Their other ends connect to the ESP32 according to the scheme above

Z-stage or Sample-stage - 6 wires + motor connection

• Sample stage is the very same as the Z-stage - you just mount it on different 3Dprinted parts.

Connect everything - mind the right pins!

• Connect the motor to the driver board
• Two of the wires are for the (+) and (-)
• Four of the wires are for the IN1 - IN4 (inputs)
• Their other ends connect to the ESP32 according to the scheme above

• Flash them with the right software from our Software-GIT.
• Power the ESP32 simply with microUSB cables.
• And it works just like that ;-)

Electronics for the SIMPLE smartphone microscope

No control via WiFi - just buttons. The Simple Smartphone Microscope is found here

• When using jumper wires you can avoid soldering.
• LED array - 3 wires + 2 wires for the button

• Z-stage - 6 wires + motor connection + 2×2 wires for two buttons

• The buttons are simply an add-on to the Electronics - connect to wires to each button and to the correct pins of the ESP32

• Power the ESP32 simply with microUSB cables.
• And it works just like that ;-)
