Name Function Description
VIN Power input for motor driver and controller: 5-15V. This port must be connected for M1/M2 motors to work.
Servo Power input for digital ports: 5-12V. If using high-current peripherals with voltage higher than 5V on digital output port (VCC end), connect to this interface to avoid damaging the Type-C USB port.
M1/M2 Ports Two motor control ports:
  M1: GPIO1 (direction control), GPIO0 (PWM control)
  M2: GPIO10 (direction control), GPIO2 (PWM control)
I2C Standard I2C interface: SDA (8), SCL (9), VCC (3.3V), GND
A-3.3V-GND Standard analog interface:
  A (blue): analog ports 3, 4, 5
  3.3V (red): power supply positive terminal
  GND (black): power supply negative terminal
D-VCC-GND Standard digital interface:
  D (green): digital ports 6, 7, 20, 21
  VCC (red): power supply positive terminal (When the Servo port is not powered, VCC is 5V; when the Servo port is powered, VCC is the input power for the Servo port.)
  GND (black): power supply negative terminal
UART RX (20), TX (21), VCC (5V), GND
  Note: The UART interface shares two IO ports with servo ports, so UART cannot be used when servos are used.
