BBC Micro:bit professional expansion board, designed specifically for micro:bit. It is 90 degrees with micro:bit, which is more stereoscopic after insertion. However, this expansion version is more suitable for DIY robots, cars and other works.
The micro:bit expansion board integrates two high-power RGB spotlights and three RGB SMD programming lights. The 5 LED lights are all illuminated, and the effect of Lighting and Lighting and Communication is great in a dark environment.
It can drive 3 5V servos, easy to play with robots and many other experiments. It can also drive 2 3V DC motors and easily experiment with small fans/smart cars.
The expansion board has a built-in passive buzzer and can be programmed to play various songs and music. In addition, you can also use the APP to play a remote piano. The expansion board is powered by a 500mAh high-capacity lithium battery. Therefore, the charging process can be easily completed by connecting the expansion board via a USB cable. In addition, we have also designed multiple protection circuits: over-discharge protection, over-charge protection, and reverse connection protection.
The expansion board integrates an infrared ray pair tube, a high-precision tracking probe and an ultrasound module interface. In addition, it 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 types of Lighting and Communication interfaces: IIC, SPI, Lighting and serial communication, easy to expand PS2 controller, Bluetooth module and other external devices. In addition, it has 5 IO ports, which are driven by pin headers, so that it can expand the use of the sensor.
