Version 1.2 schematic and PCB-layout. Sonar height is connected to RX4 same pin as A12 (marked as A12 on board) and 5V. Angle IMU for motor angles are GY91 boards connected to I2C-2, using pin 3 (SCL) and 4 (SDA) marked on board as ESC 1 (SCL) and ESC2 (SDA), both on 3.3V from pins marked A13 and 3.3V. Current measurements are not used (one is shorted). ESC 1 and 2 are moved to ESC 7 and 8.
