Data Sheet

Servo Driver HAT
HARDWARE
You can connect battery to the green socket VIN on the left for power supply, for
VIM, voltage range 6V~12V. 5V regulator on board could output 3A (MAX) current.
You can also connect 5V power supply to the POWER interface on the right, and it
could power micro:bit via 3.3V regulator.
A0~A4 can be used to set devices address of I2C, supports multiple Servo Driver
HAT connected at the same time.
GPIOs on top are interfaces of servo. Black pins are connected to GND (mostly
connect to brown wire of servo). Red pins are VCC pin connected to 5V. Yellow GPIOs
are signal wires of PWM, channel 0~15 supports 16 servos connected at the same
time.
【Note】
1. If you only connect 5V power supply to USB interface, servo cannot be driven.
2. You should connect higher power supply for higher-power servo.
3. Make sure servo are connected properly, otherwise they will not move.
