WebJun 22, 2024 · ESP8266 Pinout of NodeMCU. The NodeMCU has in total 4 different power pins: 3 pins provide 3.3V and 400mA. 1 pin marked as VIN provides 5V and can power the whole NodeMCU between 7V-12V with up to 1A. and in total 5 ground pins to close the electric circuit. The ESP8266 has a lot of communication pins: 2x UART. WebThe board can be supplied with power either from the DC power jack (7 - 12V), the USB connector (5V), or the VIN pin of the board (7-12V). Supplying voltage via the 5V or 3.3V pins bypasses the regulator, and can damage your board. We don't advise it. 3V3. A 3.3 volt supply generated by the on-board regulator. Maximum current draw is 50 mA. GND.

WebOct 16, 2012 · These are 3.3 volt logic pins. A voltage near 3.3 V is interpreted as a logic one while a voltage near zero volts is a logic zero. A GPIO pin should never be connected to a voltage source greater than 3.3V or less than 0V, as prompt damage to the chip may occur as the input pin substrate diodes (shown as parasitic FETs in Figure 1) conduct.
