A-Star 32U4 Robot Controller SV - rozszerzenie do Raspberry P


In our offer, there are two types of extensions of the A-Star for the Raspberry Pi:


Thanks to special connectors, the device can be mounted directly on the GPIO pinsof the Raspberry Pi in version 2B / B+ /A+(minicomputer sold separately). The systems communicate with each other via the I2C bus using the built-in voltage converter 3.3 V to 5.0 V. On board is voltage regulator with high performance which provides power to the Raspberry Pi.

Example of connecting the motors.
