This expansion board is designed with bilateral symmetry, an onboard micro:bit board socket, 18650 battery socket, USB power supply interface, 3-5v external power interface, 4 programmable RGB lights, buzzer, I2C interface, WIFI camera serial port, and a variety of motor interfaces. It also can be connected with 2 channel stepper motors, 4 channel DC motors, 8 channel servos, coupled with stable power supply scheme and various protection circuits. There are 17 pin header IO ports and 10 alligator clip interfaces to support our sensor modules. The WIFI camera serial interface, IIC interface, and LEGO holes make it possible for users to expand into more interesting projects. You can build your own shape with the LEGO bricks, connect electronic devices, and control it by micro:bit programming. It is an excellent choice for your robotic projects based on Micro:bit!
