On-board comes with AMS1117 chip, and you can power micro bit via connecting external DC 4.75-12V.
This breakout board breaks out all the pins and power of micro bit development board to both side female header, to allow easy component soldering on the board, and you can also connect the circuit using small breadboard.
Keyestudio micro bit joystick breakout board comes with AMS1117 chip. You can also connect external DC 7-12V to power for micro bit development board.
It can be used to simulate the mouse keyboard. On-board 3V、G、P0、P1 are connected to microbit board to imitate the serial port, thus connect the Bluetooth devices.
In order to facilitate the wiring of micro bit development board, we specifically design this breakout board. This board breaks out all the pins and power of micro bit development board to both side female header, so you can connect it to other components using jumper wire.
in includes a micro: bit control board, 1m USB cable and a battery holder (battery not included, wire length 160mm). Note that USB cable is for uploading program to micro:bit. Battery holder is for power supply, and it comes with a switch button, very convenient for controlling.
