High current electrical equipment must be powered separately, otherwise it is easy to burn the board! ! ! The 3.3V output power supply on the board is close to zero. This pin is the V3 pin that connects to the CH340 Like NRF24L01 (board 3V3 power supply is insufficient to communicate), ESP8266, OLED and other modules are best to use an expansion board or connect to another 3.3V power supply. (For the record! ! !) The USB interface of USB 3.0 of some computers will fill current, which will cause the power chip to burn. Please make it Use USB2.0 interface to power and download programs! ! !
