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