Micro:bit Breakout Board ( Octopus:bit)
We have ✅ 4 available of the EF-EF03405 in our Sydney warehouse. An extra 100 units available with a short lead time.
The Octopus:bit is a breakout board for the BBC micro:bit that extends all GPIO ports (P0–P16, P19–P20) into colour-coded pin headers with VCC and GND alongside each I/O pin. This makes connecting sensors, servos, and other modules quick and easy — especially with the ElecFreaks Octopus series of accessories.
A built-in voltage boosting module lets you switch the working voltage of select pins (P8, P9, P11–P16) between 3.3V and 5V, enabling compatibility with both 3.3V and 5V modules. The board also breaks out serial, I2C (3 channels), and SPI (2 channels) interfaces.
