## Description

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. Key Features Full GPIO Breakout – All micro:bit pins (P0–P16, P19–P20) with colour-coded VCC/GND 3.3V/5V Voltage Switch – Selectable voltage on P8, P9, P11–P16 via on-board booster I2C Support – 3 channels for connecting I2C devices SPI Support – 2 channels for SPI devices Serial Port – Broken out for UART communication or board-to-board serial Octopus Compatible – Pin layout matches ElecFreaks Octopus series modules Specifications Input Voltage – 3.3V (powered via micro:bit edge connector) Output Voltage – 3.3V or 5V (switchable on select pins) Dimensions – 150 × 100 × 20mm Weight – 33.4g Ideal For Expanding micro:bit GPIO for sensor and actuator projects Programming education with micro:bit Smart device prototyping Connecting 5V modules to the 3.3V micro:bit Note: BBC micro:bit board is not included.
