Keyestudio micro bit Sensor Shield V2 (Black and Eco-friendly)

In the educational market, micro:bit control boards are becoming more and more popular. However, a single micro:bit control board is not easy to test with other sensor modules. We particularly design this keyestudio sensor expansion board V2 for micro:bit.
The sensor shield V2 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.
Moreover, it also 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 the micro:bit board through a black 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.
