ESP8266で3VリレーをON/OFFしようとしていたが、定格電流が170mAのものの動作で失敗した。

GPIOの出力電流はどのくらいなのだろうか。

1. 12mA here refers to the source current and sink current is greater than 12mA.
2.12mA is for per pin and each pin is the same.
3. Drive capacity current of all GPIO pins total can be 16 x 12 mA.

The sink current of GPIO is about 20mA.
