BPI:bit robot expansion board - expansion board for building a robot with BPI:bit and micro:bit

Description

An expansion board for building a vehicle or a mobile robot designed to work with BPI:bit or micro:bit modules. Thanks to numerous connectors and built-in drivers, the board allows you to control 4 DC motors and 4 servos. It is equipped with a connector with a UART interface, which can be used for communication or connecting a distance sensor, and connectors with SPI and I2C interfaces. The user also has 7 3-pin connectors for connecting additional sensors. The set is powered by a microUSB socket and a 12 V screw connector when the outputs of motors or servos are used. The expansion board is perfect for the projects of mobile robots or remotely controlled vehicles. Full documentation is available on the product Wiki page.
