Raspberry Pi Official Expansion Board

The official Raspberry Pi expansion board offers endless possibilities with its built-in sensors, LED matrix, and local control interface (joystick). It features a thermometer, humidity sensor, barometer, accelerometer, gyroscope, and magnetometer. The 8x8 LED matrix allows for visible displays without an additional screen, showing individual points or bars that can be animated. The joystick provides access to 5 functions: up, down, right, left, and vertical click. It can emulate keyboard arrow keys and the Enter key with the central click, making it a valuable educational tool.
