Technical overview
- The module acts as a driver and control unit for up to 16 servo motors.
- Control is performed through the micro:bit's I2C bus.
- Each of the 16 channels can be addressed independently.
- 12-bit resolution enables fine-grained position control of the servos.
- Wiki resources include a user manual, schematic and demo code.
- Chips referenced in the datasheets are MP1584, PCA96 and RT9193.
- A suitable programming environment is the micro:bit MakeCode website.
- A Bluetooth app is also available.
Notes and version constraints
- No specific commands or code lines are given in the source document; exact API calls must be derived from the demo code.
- Power supply, current draw and maximum servo current values are missing from the source and should be verified before assembly.
- I2C addresses and configuration parameters are not included in the text and require checking the datasheet (e.g., PCA96).
- Compatibility with specific micro:bit versions is not explicitly confirmed.
- Warranty, safety or certification details are absent; these should be confirmed with the supplier.
