what is the difference (esp8266 nodemcu v3 vs esp8266 wemos d1mini )?

Postby engkhaledeisa » Sun Jul 07, 2024 8:41 am

the project here is working fine with esp8266 d1mini....but I need to make it work on esp8266 nodemcu v3 ....and believe my me and my colleague tried several times when we told they are same just replace this with that but it didnot work ...we tried different options like adding different pull up resistors ,capacitors ,logic converters but still nothing worked .....what I should add or modify with project to work with esp8266 nodemcu v3 like it worked with esp8266 d1mini ?...should I add voltage regulator as I heard there is a difference in this area

You need to be a bit more specific. What doesn't work? Is you wiring correct? Did you flash MCU with correct binary? Does it boot? Does it communicate with sensors? Does it detect button pushes?

all of that works with d1mini but when I connect nodemcu v3 it doesnot respond so what is the difference ....I try to figure out the difference from looking at their both schematics but still didnot reach anything

Again, please be more specific. I'm not familiar with this project, therefore it's a bit hard to understand what do you mean by "connecting". Do you use USB driver, serial console or WIFI or some other means of connection? In general, you should be able to connect to MCU regardless of any connected buttons, sensors or other peripherals.

Out of curiosity, I've looked up the project the OP is trying to make work - https://github.com/projectswithalex/Rea ... ng-Module/. It consists of 4 devices, which are communicating with each other via ESPNOW.

I guess the best way to find out what's causing the issue is download arduino IDE and start debugging.

Both boards have different numbers of I/O pins. It is possible that the library that you're using is not compatible with nodemcu v3.
