ELECFREAKS Octopus:bit (Breakout Board For micro:bit)micro:bit breakout board is a kind of breakout board for micro:bit. It can lead out GPIO port, serial port, IIC port, and SPI port on the micro:bit board. The biggest feature of Octopus:bit is that it can switch electric levels for some GPIO ports, which makes micro:bit available to be adapted to 5V sensors.elecfreaks octopus:bit (breakout board for micro:bit)Octopus:bit Key Features & HighlightsExtends essential GPIO ports (P0–P16, P19–P20) and adds serial, I²C (3 channels), and SPI (2 channels) interfaces. Includes a voltage boosting switch for select ports (P8, P9, P11–P16), enabling 3.3V to 5V conversion—ideal for integrating 5V modules with your micro:bit.Features color-coded VCC and GND pins beneath each I/O port, enhancing convenience and compatibility with Octopus series modules.Supports direct serial communication between two Octopus:bit boards for advanced setups.elecfreaks octopus:bit (breakout board for micro:bit)Octopus:bit SpecificationsDimensions: 60mm x 62.1mm x 11mmVersion: v2.0Weight: 24.1gInput Voltage: 3.3VVoltage Boosting: Switchable voltage for P8, P9, P11~P16 between 3.3V and 5VGPIO Ports: Extended GPIO ports: P0~P16, P19~P20I2C Port: SupportSPI Port: Support
