IO expansion module designed for use with the micro:bit educational development board. The board exposes 20 IO pins along with 3.3 V power and GND lines, enabling direct connection of sensors and electronic modules. The design includes a built-in passive buzzer and a voltage stabilization circuit allowing the module to be powered via a 6–12 V DC connector or a microUSB port
Description
IO expansion module designed for use with the micro:bit educational board. The design exposes 20 input/output pins available on the micro:bit edge connector. Each IO pin includes additional 3.3 V and GND power pins, simplifying the connection of sensors, communication modules, and actuators without the need for additional interface boards.
The board includes a passive buzzer allowing generation of sound signals in educational and prototype projects. A 4-pin I2C interface connector is also available for connecting compatible peripheral modules such as displays or sensors.
The power circuit allows the module to be supplied through a DC connector with a voltage range of 6 to 12 V or through a microUSB port. The power pins available next to the IO lines provide a fixed 3.3 V supply compatible with the logic level of the micro:bit board. The design supports the development of educational systems, measurement setups, and simple robotics projects using multiple peripheral modules.
Note!
The presented version of the module does not include the VCC jumper cap voltage selection jumper or a 5 V pin. Only 3.3 V is available on the power pins next to the IO connectors. The reference graphic may show a board version with a 3.3 V / 5 V voltage selection option, while the remaining structural elements of the module remain the same.
