本文是“攻玉计划”的一部分,翻译自https://randomnerdtutorials.com/esp8266-pinout-reference-gpios/ 本文旨在介绍 ESP8266 的引脚定义、引脚功能及如何使用它们。 ESP-12E 模块拥有 17 个 GPIO 引脚。但在各个开发板上,ESP8266 芯片的 GPIO 引脚并不一定全部引出,而且某些引脚不建议使用,某些引脚有非常特殊的功能。
We’re using a 100 Ohm and a 220 Ohm resistor, so that the Vout is 1V. Recommend reading:ESP8266 Pinout Reference: Which GPIO pins should you use? 1. ESP8266 NodeMCU Analog Read with Arduino IDE This section shows how to read analog values with the ESP8266 using Arduino IDE. Install ...
Confused as come across other pinout configurations too. Thank you. Reply Ed Darby March 12, 2015 at 12:48 pm Hi Rui, thanks for your great tutorials Just a quick question, you mention you could use this to control a relay. Would I just connect the gpio pin to the control pin ...
I've used several versions of PCM5102 DAC boards purchased from eBay. They've all had the same pinout, no matter the form factor. There are several input configuration pins beyond the I2S interface itself that need to be wired: 3.3V from ESP8266 -> VCC, 33V, XMT GND from ESP8266 ->...

power supply that accepts voltages between 7 to 12v DC into the DC socket and gives the board a solid stable low ripple 5v at 1 amp. Note that the ESP8266 itself is a 3.3v and all the IO is using 3.3v. All the pinout are nearly labelled and you can just add your circuitry easily...
Recommended reading:ESP8266 Pinout Reference: Which GPIO pins should you use? ESP8266 12-E NodeMCU Kit The ESP12-E NodeMCU Kit is one of the most used ESP8266 development boards. It features 4MB of flash memory,access to 11 GPIO pins, and oneanalog-to-digital converter (ADC)pin with 10...
Here’s the MCP1700-3302E pinout. It has GND, Vin and Vout: Other LDOs should have the same pinout, but you should always search for your LDO’s datasheet to verify its pinout. ESP8266 Circuit with LDO and Li-ion Battery Here’s the parts required to design the voltage regulator for...
The HX711 amplifier communicates via two-wire interface. You can connect it to any GPIOs of your chosen microcontroller. We’re connecting the data pin (DT) toGPIO 12(D6) and the clock pin (CLK) toGPIO 13(D7). You can use any other suitable pins (check the ESP8266 pinout guide)....
UNO style boards with a Wemos R32(ESP32) label are also available at low cost with the same pinout. Unfortunately the typical UNO/mcufriend TFT display board maps LCD_RD, LCD_CS and LCD_RST signals to the ESP32 analogue pins 35, 34 and 36 which are input only. To solve this I linke...
