Все о продукте

BBC micro: bit 2 Single - educational module. Thanks to the BBC micro:bit, children can easily create their own games or more complex projects thanks to the ability to program in the Scratch graphical editor. BBC micro:bit 2 is based on the NRF52833 chip with an ARM Cotex M4 core, and its board includes the following elements: MEMS microphone, speaker, touch button (logo), accelerometer, magnetometer, Bluetooth 5.0, 5 x 5 LED display " Tact Switch buttons and others. The latest version of the micro:bit module was equipped with components such as a MEMS microphone and speaker for creating interactive projects, a 5 x 5 LED matrix for light detection, two programmable buttons, a RESET button, a touch button (logo), a compass, an accelerometer and Bluetooth 5.0. In addition, the BBC micro:bit 2 has an LED that indicates power and microphone activity. The individual elements were labeled and described on the PCB. The board also has five wires for "banana" cables that allow you to connect an auxiliary power supply and other peripherals such as servos or RGB LEDs.
