Official NodeMCU 1.0/V2 development board What it maybe means is that Amica is the “endorsed” producer and DOIT & LoLin are not. It’s my understanding that with open-source hardware there’s no such thing as official boards. I don’t really understand the notion of official. NodeMCU posted a photo on Facebook which shows official and unofficial V2 boards. He owns the amica.io domain.Īlthough not officially part of the original NodeMCU team Gerwin designed a name for the devkit v1, called Amica. It’s a brand name created by the Dutch Gerwin Janssen who seems to spend a lot of time in Shenzhen, China. Many V2 boards are created by or at least labeled with ‘Amica’.

What’s the relationship between NodeMCU and Amica? Here’s what I know. There are clearly better alternatives.ĪND what’s LoLin got to do with WeMos? I wish I knew…The pin layout you see here was originally hosted on but the link is now dead.Īnnouncement Relationship between NodeMCU and Amica Because of its size I would never use it. Watch out though for the difference in size! This LoLin board is significantly larger than the Amica and DOIT V2 boards. LoLin decided to use one of the two reserve pins for USB power out and the other for an additional GND. If you compare the pin layout there’s only a tiny difference to the V2 layout. Pin layout LoLin NodeMCU development board V3. Among others they claim their USB port to be more robust. Turns out that V3 is a “version” invented by producer LoLin to signify minor improvements to the V2 boards. Hence, there’s no official 3rd generation board. So, what’s with the V3? NodeMCU haven’t released a new specification so far. Pin layout of 2nd generation ESP8266 NodeMCU development board. The chip was upgraded from a ESP-12 to a ESP-12E.Ģnd generation ESP8266 NodeMCU development board The V2 fixes the short comings of the initial board, it’s more narrow and fits nicely into bread boards. Pin layout of 1st generation ESP8266 NodeMCU development board. It comes with a ESP-12 module and 4MB flash memory.ġst generation ESP8266 NodeMCU development board They seem to be produced by Amica primarily (my guess). There’s a blog post with a picture that demonstrates this quite clearly. Its 47mm x 31mm mean that it covers all 10 pins of a regular bread board which makes it very inconvenient to use. The original but now outdated dev kit is usually sold with an outstanding yellow board and is very wide. Both generations use ESP-12 chips with 4MB flash but the 2nd generation uses the newer and enhanced ESP-12 E. Comparison of NodeMCU development boardsġst and 2nd generation boards are easy to tell apart because their size is quite different. There currently are three primary producers: Amica (see ‘ NodeMCU and Amica‘ below), DOIT/SmartArduino, and LoLin/WeMos. What further contributes to the naming jungle is precisely the fact that the hardware is open-source and anyone can produce and market NoduMCU development boards. A while a ago I started noticing this one product marketed as V3 even though it looks like a regular V2 board to me. What I put in the 3rd column is just my observation of products in (Chinese) online shops such as Banggood and AliExpress.

It’s unfortunate that there’s a mixup of version and generation names. Comparison of NodeMCU development boards.

Since this article has become quite long, and to give you an idea what to expect, I decided to put a TOC here:

#ESP8266 NODEMCU LUA CP2102 ESP 12E INTERNET WIFI DEVELOPMENT BOARD ARDUINO 1.8.5 UPDATE#

Update : if you found here because you’re actually interested in ESP32 devkits look no further! The amazing ThingPulse ePulse from yours truly consumes only 25μA in deep sleep. The comparison can be confusing not because there are many different boards (there’s only 3) but because there are several names for the same thing. A comparison of ESP8266 NodeMCU development boards must inevitably also compare the ESP8266 chips used on those boards.
