Key Features
- The sensor shield breaks out all the PIO ports on the micro:bit control board into 3PIN interface (GND, VCC, Signal), very easy to connect the micro:bit control board and other sensor modules.
- The microbit sensor shield extends some commonly-used serial communication interfaces into pin or female headers with 2.54mm pin pitch, such as I2C and SPI communication pins. So that this shield will allow communication between micro:bit control board and other communication devices.
- You can power your micro:bit board through a yellow DC jack (DC 7-9V) or a mciro USB port (DC 5V) on the shield.
- When power the sensor, you could select the supply voltage 3.3V or 5V via jumper cap V1 and V2.
