Have you try driving a bunch of servo motors by micro:bit main board but failed? Micro:bit main board outputs the voltage DC3.3V, but servo motors generally need to drive with DC5V; the driving current of micro:bit main board is very small, it’s also not enough to use the IO pins to drive a bunch of servo motors.
It’s what you’ve been waiting for － keyestudio 16-channel SERVO Shield for Micro:bit. It mainly integrates PCA9685PW chip, which communicates with micro:bit main board through I2C.
The SERVO Shield has 16 IO pins for steering 16 Servo motors. For easy wiring, we extend the control pin of each channel to G V S interface － 3pin header with a pitch of 2.54 mm. The voltage of V pin on the Servo shield is 5V.
The Servo Shield can be supplied with power either from the Micro USB connector (DC5V input), or 2 green terminal blocks (DC 7-12V input).
Besides, the Servo shield also comes with 8 golden edge connectors. It allows an easy way to connect additional circuits and sensors/modules hardware to the edge connector on the BBC micro:bit or 3.3V output pin.
