Octopus:bit (Breakout Board For micro:bit)

Το Octopus:bit είναι ένα είδος πλακέτας breakout για micro:bit. Μπορεί να οδηγήσει σε θύρα GPIO, σειριακή θύρα, θύρα IIC και θύρα SPI στην πλακέτα micro:bit. Το μεγαλύτερο χαρακτηριστικό του Octopus:bit είναι ότι μπορεί να αλλάξει ηλεκτρικά επίπεδα για ορισμένες θύρες GPIO, γεγονός που καθιστά διαθέσιμο το micro:bit για προσαρμογή σε αισθητήρες 5V.

1 x micro bit breakout board(Octopus:bit)

Input voltage: 3.3V（powered by the edge connector of micro:bit）

Extend all the GPIO ports(P0~P16, P19~P20).

Beneath each I/O port, there are pins for VCC and GND. These pins are differentiated by different colors, which enable you to connect your extension module easily. The spread of pins is fully compatible with the Octopus series products.

With a voltage boosting module, you can shift the working voltage of P8, P9, and P11~P16 between 3.3V and 5V through the voltage switch.

Lead out the serial port, I2C port, and SPI port, among which I2C can connect 3 channels of I2C devices and SPI can connect 2 channels of SPI devices.

Available for direct serial port communication between two breakout boards.

It is suitable for all conditions that require micro:bit GPIO such as programming education, smart device creation, and so on.
