a temperature sensor, periodically reporting data to a server (like a RPi) over wifi. A common usage is to have ESP8266 sensor node(s), e.g. In this example we will be using the number 10, but you can test with other values. Serial.begin (115200) We will now print the same number in different bases. The ESP32 NodeMCU board (2nd link) is a relatively new product and community support isn't yet up to the level of the ESP8266 product.ģ) To emphasize the previous responses, there are several development environments which allow one to use the ESP8266 as a stand-alone network connected node without physical connection to another processor like a RPi. This method receives as input the baud rate, which should later match the one we are going to use on the Arduino IDE serial monitor. The ESP-01 (your 1st link) is very sensitive to power supply layout and will likely lead to frustration. ![]() It will be easier to integrate and will provide a much faster and more versatile wifi capability.Ģ) If you go the ESP route for a project, I'd recommend starting with an ESP8266 NodeMCU board rather than either of the products you've linked. 1) If you simply want to add wifi capability to an RPi-2B then a usb wifi adapter is a better approach.
