NodeMCU is an open-source Lua based firmware anddevelopment boardspecially targeted for IoT based Applications. It includes firmware that runs on the ESP8266 Wi-Fi SoC from Espressif Systems, and hardware which is based on the ESP-12 module. NodeMCU Development Board Pinout Configuration 特殊引脚情...
In this tutorial we’ve shown you how to read analog values using the ESP8266 analog pin (A0). One important thing to notice is that the ESP8266 analog input range is either 0-1V if you’re using a bare chip, or 0-3.3V if you’re using a development board. Either way, you shou...
If you are very good with a soldering iron, this ADC capability can be accessed on any version of the ESP8266. The above graphic is the pinout for the EX chip. The chip on the ESP-1 has the pinout, just not the physical connection. Some steady hands and a small iron could tap it....

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 ...
The ESP8266-12E breakout board has the following pinout. Digital input/output in ESP8266 ESP8266 GPIOs are 3V3 compatible and can sink or source a maximum of 40 mA. As we can see, GPIO6, GPIO7, GPIO8, and GPIO11 are not available for input/output in the ESP-12E breakout board, wh...
