{"title":"Micro:bit Breakout Board ( Octopus:bit)","handle":"micro-bit-breakout-board-octopus-bit","url":"/products/micro-bit-breakout-board-octopus-bit","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.\n\nA 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.\n\nKey Features\n\n\nFull GPIO Breakout – All micro:bit pins (P0–P16, P19–P20) with colour-coded VCC/GND\n\n3.3V/5V Voltage Switch – Selectable voltage on P8, P9, P11–P16 via on-board booster\n\nI2C Support – 3 channels for connecting I2C devices\n\nSPI Support – 2 channels for SPI devices\n\nSerial Port – Broken out for UART communication or board-to-board serial\n\nOctopus Compatible – Pin layout matches ElecFreaks Octopus series modules\n\n\nSpecifications\n\n\nInput Voltage – 3.3V (powered via micro:bit edge connector)\n\nOutput Voltage – 3.3V or 5V (switchable on select pins)\n\nDimensions – 150 × 100 × 20mm\n\nWeight – 33.4g\n\n\nIdeal For\n\nExpanding micro:bit GPIO for sensor and actuator projects\nProgramming education with micro:bit\nSmart device prototyping\nConnecting 5V modules to the 3.3V micro:bit\n\n\n\nNote: BBC micro:bit board is not included.\n\n\nResources\n\nOctopus:bit User Guide (ElecFreaks)\n","vendor":"ElecFreaks","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":4698,"title":"Default Title","sku":"EF-EF03405","price":15.58,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":102,"option1":"Default Title"}]}
