Note
1. When using micro:bit power supply, IO port current is less than 200ma, please do not connect high current devices (such as large servo, DC motor), otherwise it will burn out micro:bit.
2. When using a 5V external power supply, you can drive multiple small servos, but please note that the current should not exceed 1A.
3. If you use the high-low read function of the pin, you must set the pull-down on the pin.
4. If P0 is used as a normal IO port, the buzzer toggle switch must be placed on the off side, otherwise the buzzer will sound or the IO read value will be abnormal.
5. Use the shared pin with the Micro:bit dot matrix (such as 3, 4, 5, 6, 7, 8, 9, 10, 11), remember to disable the dot matrix screen on the software.
6. Do not use IO19,20.19and 20 can not be used as an IO port, only for I2C communication.
