Description:
1. Onboard Micro:bit interface, which can be directly inserted.
2. I2C interface control, only 2 signal lines are needed to realize the servo drive
3. Support up to 16 servo or PWM outputs, each with 12-bit resolution.
4. The onboard 5V voltage regulator chip can output up to 3A current, which can be connected to the battery for power supply through the VIN terminal.
5. The onboard standard servo interface can be connected to common servos.
6. Reserve I2C control interface for easy access to other main control boards
Product parameters:
Power supply voltage: DC6V-12V (green terminal) or 5V (Micro USB interface)
Servo voltage: DC5V
Logic voltage: DC3.3V
Driver chip: PCA9685
Control interface: I2C
Hole size: 3.05mm
Product size: 65.08*36.50mm
Special Note:
1. If the power supply is only connected to the USB port of the micro:bit, the expansion has no 5V power supply and cannot drive the servo.
2. If the high-power servo is connected, the power supply may be insufficient, and more power needs to be connected.
Packaging List:
1 x Micro bit servo driver board expansion board
1 x English manual
