![]() The boards like the NodeMcu and WeMos D1 Mini, etc. Also, you need additional components to be able to use the ESP-01 by itself. The latter usage is more common with the ESP-01 because it only has a couple of the GPIO pins broken out, so it's of limited use as a standalone board. You can use the Arduino IDE to upload sketches to the ESP-01 or you can connect the ESP-01 to a regular Arduino board using a serial connection and then write your sketch for the regular Arduino board, which controls the ESP-01 using AT commands. The name of the "the ESP8266 8 pin module" is ESP-01. You use the esp8266-01 8 pinner by giving AT command to it via the serial port. Just to be clear, one does not overwrite the code in the ESP8266 8 pin module right? yes/no. If you're talking about the NodeMcu hardware, was the board you were looking at an ESP8266 board? If so, then it does not have Bluetooth functionality. If you're talking about the NodeMcu firmware, does it provide access to the ESP32's Bluetooth functionality? I have no clue. I see no mention of Bluetooth on the NodeMcu. It seems that the ESP32 supports WiFi AND Bluetooth, is this correct? The NodeMcu hardware can be used with Lua, C++, C, assembly, Python, and probably a few other languages.Ĭan you consider a ESP32 an arduiino with a wi-fi chip? The NodeMcu firmware is for use with Lua. It seems that the NodeMcu uses a Lua programming language rather than the arduino development system in C++. Pictures I have seen seem to show that the ESP32 and the NodeMcu are the same, yes/no? You can also purchase the ESP8266 module, without the support components provided by the development boards. You will find this microcontroller on a variety of development boards, in a variety of forms. You can also purchase the ESP32 module, without the support components provided by the development boards.ĮSP8266 is the name of a microcontroller made by Espressif. Now, the "NodeMcu" name is being used to market ESP32 boards as well.ĮSP32 is the name of a microcontroller made by Espressif. Over time, the NodeMcu boards became less popular in the Arduino world because the similarly priced WeMos D1 Mini came out with the same functionality, but in a smaller form factor. ![]() To make things more confusing, multiple companies marketed boards with the name "NodeMcu", but with small hardware differences. It is common for people with no interest in the Lua programming language to buy "NodeMcu" boards and program them with the Arduino IDE, which erases the NodeMcu firmware from the board. ![]() In the early days of the hobbyist community's adoption of the ESP8266, ESP8266 development boards were marketed with the name NodeMcu and the term "NodeMcu" started to be associated more with the hardware than the firmware. "NodeMcu" is the name of a firmware originally for the ESP8266 microcontroller, with support for the ESP32 microcontroller added more recently, that allows you to program these microcontrollers using the Lua programming language. ![]()
