How do I know what version of NodeMCU I have?
Look for the two buttons RST and FLASH. If the text is above the buttons (as in between the rest of the board/components and the buttons, then that is a v2 board. If the text is between the buttons and the usb port, then that’s either a v1 or a v3 depending on other things.
What is NodeMCU for?
Overview. NodeMCU is an open source firmware for which open source prototyping board designs are available. The firmware is based on the eLua project, and built on the Espressif Non-OS SDK for ESP8266. It uses many open source projects, such as lua-cjson and SPIFFS.
What is NodeMCU in simple words?
NodeMCU is an open source firmware for which open source prototyping board designs are available. The name “NodeMCU” combines “node” and “MCU” (micro-controller unit). The firmware uses the Lua scripting language. The firmware is based on the eLua project, and built on the Espressif Non-OS SDK for ESP8266.
What’s the difference between NodeMCU V2 and V3?
Turns out that V3 is a “version” invented by producer LoLin to signify minor improvements to the V2 boards. Among others they claim their USB port to be more robust. Pin layout LoLin NodeMCU development board V3. Source: http://www.wemos.cc/wiki/Hardware/Pin If you compare the pin layout there’s only a tiny difference to the V2 layout.
Which is the 2nd generation NodeMCU Development Board?
Comparison of NodeMCU development boards. 1st and 2nd generation boards are easy to tell apart because their size is quite different. Both generations use ESP-12 chips with 4MB flash but the 2nd generation uses the newer and enhanced ESP-12E.
What’s the difference between ESP8266 and NodeMCU?
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.
What kind of UART chip does NodeMCU V.2 use?
V.2 uses the CP2202/2402, the V3 uses a CH340G (Watch out, different drivers!) This is a smaller version of the nodeMCU V.3. It has less pins. The missing pins are just power pins (GND, VCC), so all functions are availlable. It uses the CH340G UART chip.
