Source: The power source is selected automatically. Web this article is a guide for the esp8266 gpios: I like this device it’s very low cost and effective value wifi microcontroller.

Web the esp8266 wemos d1 mini has only one 3.3v output pin and also only one ground pin to power an external circuit. If using more than 12v, the voltage regulator may overheat and damage the device. Hardwareserial shield for ebyte e32 e22 e220 lora devices When you think about it, it makes a lot of sense to include a single adc channel. Pinout diagrams, their functions and how to use them. The wemos d1 mini has a 3.3v and 5v output to power. Web the d1 mini has a micro usb for auto programming. If your project is ready for action you could put the wemos d1 mini on this custom pcb and more than one 3.3v pin and one ground for the pcb is not necessary. Arduinoer esp8266OLED, esp8266Arduino library for I2COLED displays from Not all gpios are exposed in all esp8266 development boards, some gpios are not recommended to use, and others have very specific functions.
