OCTOPUS: BIT MICRO:BIT BREAKOUT BOARD EF03405

Shield d’expansion E/S Freaduino Octopus de Elecfreaks permettant d’accéder à toutes les entrées/sorties d’une carte micro:bit V1 ou V2 via des connecteurs 3 broches (Vcc, Gnd, Signal).

Le niveau logique des connecteurs jaunes est en 3,3 Vcc. Le niveau logique des connecteurs bleus et des liaisons TTL est sélectionnable par interrupteur (3,3 ou 5 Vcc).

Caractéristiques:

• Niveau logique sélectionnable par interrupteur
• Entrées sorties:
  – 16 x E/S digitales
  – 1 x port Uart mâle et un port Uart femelle
  – 3 x ports I2C
  – 2 x ports SPI
• Dimensions: 72 x 62 x 13 mm

Référence Elecfreaks: EF03405
Compatible micro:bit V1 et V2

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.
