 # Hardware
-## ESP32
-The embedded code of the DIY active pedal runs on an ESP32 microcontroller. The PCB design was developed to proof the concept. It holds the ESP32 breakoutboard, the ADC breakoutboard, a levelshifter and connectors. Currently the version 3 of this PCB deisgn is usedm which introduced sensorless homing of the servo. The PCB deisgn and pinout diagram can be found [here](Wiring/Esp32_V3).

+### Wiring
+The PCB has some three connectors. Please wire as follows:
+
+#### Servo motion port
