microbit 利用時の一般的な注意とか FAQ
When using the Micro:bit power supply, IObit IO port drive capability is very weak, IO port current is less than 200mA, please do not connect high current devices (such as large servo MG995, DC motor), otherwise it will burn out the Micro:bit , you must fully understand before using what the device current conditions needed
When using a 5V external power supply, you can drive multiple small servos, but please note that the maximum current is 1A!
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, otherwise it will be a bit of a screen burst
The USB port allows a maximum input current of 1A.
Do not place it on a metal surface to avoid short circuit
