In this chapter, we’ll look at the non-Wi-Fi specific functions of the ESP8266. Low cost wifi module ESP8266 I'm 100% new to this topic and after some searching for NodeMCU and ThingSpeak and some minutes of shameless ESP8266_Schematic. It will make NodeMCU more easy. A NodeMCU ESP8266 WiFi module. NodeMCU-32S contains firmware that can run on ESP32 Wi-Fi SoC chips, and hardware based on ESP-32S modules. 10 GPIO, every GPIO can be PWM, I2C, 1-wire. Yes it can be of course REQUIREMENTS 1. NodeMCU ESP8266 ESP12E DevKit & Arduino IDE (Simple IoT Prototyping): NodeMCU DevKit is a WiFi embedded microcontroller board, effective in building IoT(Internet of Things) prototypes. It includes firmware which runs on the ESP8266 Wi-Fi SoC, and hardware which is based on the ESP-12 module.
