Micro:bit control boards are becoming more and more popular in the educational market.
However, a single micro: bit control board is not easy to test with other sensor modules.
We specifically designed this keyestudio sensor expansion board V2 for micro:bit.
The Sensor Shield V2 splits all PIO ports on the micro: bit control board into the 3PIN interface (GND, VCC, signal), making it very easy to connect the micro: bit control board and other sensor modules.
In addition, it extends commonly used serial communication interfaces such as I2C and SPI communication pins to a 2.54mm pin pitch pin or female header.
Allow this shield to communicate between the microbit control board and other communication devices.
You can power the micro: bitboard through the black DC jack (DC 7-9V) or mciro USB port (DC 5V) on the shield.
When powering the sensor, you can choose the supply voltage 3.3V or 5V through the jumper cap V1 and V2.
