This expansion board is designed specifically for micro:bit. Compared with the traditional horizontal expansion board, this expansion version is more suitable for DIY robots and cars. The three-dimensional shape means that the micro:bit will be facing you.
The micro:bit expansion board integrates two high-power RGB colorful searchlights and three SMD RGB programming lights. The 5 LED lights are all brightly lit.
It can drive 3 5V servos, robots and many other experiments. It can also drive 2 3V DC motors and small fans/smart cars.
A passive buzzer is integrated on the expansion board, and the buzzer can be programmed to play music.
The expansion board is powered by a 500mAh high-capacity lithium battery, and the charging process can be easily completed by connecting the expansion board via a USB cable. There are also multiple protection circuits: over-discharge protection, over-charge protection, and reverse-connection protection.
The expansion board integrates an infrared ranging pair tube, a high-precision tracking probe, and an ultrasonic module interface. This makes it easy to transform the entire expansion board into a smart car chassis for a micro:bit smart car.
The expansion board provides three kinds of communication interfaces: IIC, SPI, serial communication, easy to expand PS2 controller, Bluetooth module and other external devices. In addition, we have reserved 5 IO ports, which are led out by pin headers, so you can expand your sensor usage.
