Programmable system equipped with the famous from Arduino Leonardo, microcontroller Atmega32u4 with installed bootloader which enables programming via the installed microUSB slot. It has driver of motors which provides control of the direction and speed of two DC motors with parameters of up to 11 V / 1.8 A.

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 pins of the Raspberry Pi in version 2B / B+ /A+ (minicomputer sold separately). The models communicate with each other via the I2C bus using the built-in voltage converter 3.3 V - 5.0 V. On board is a voltage regulator with high performance which provides power to the Raspberry Pi.

Example of connecting the motors.
