The NodeMCU Inc manufactured development kits.These are low-cost breadboard-friendly modules which are aimed at providing a simple to configure and set up, hardware platform for developing ESP8266-based Lua IoT applications.

- Sun Jan 22, 2017 10:35 am #61345 NodeMCU boards aren't so good with battery power. The voltage regulator on the board is not very efficient and even if powering the board directly to its 3.3v pin then the other components on the board keep using power even when the ESP is deep sleeping so you can't get the deep sleep current consumption to be very low.

Jul 24, 2017 · i have a problem with my NodeMCU (ESP8266). I have the NODEMCU FIRMWARE PROGRAMMER to load the bin-file from spacehuhn with the Wifi Jammer Code on my Board but there i can't select a COM Port and in Arduino i also can't select a COM Port...?! Can anyone help me? I don't know and in the Device-Manager i can't find Ports(COM & ...). …

- Sat Sep 03, 2016 2:34 pm #54371 I have tried the following on a HUZZAH and 2 different nodeMCU 1.0 boards (12E) that I am programming via the Arduino IDE 1.6.10 (I can also use platformIO as an IDE). I am trying to use the internal pullup on various pins (D8 or D4 which correspond to GPIO15 GPIO2 respectively) without any success.

Oct 14, 2019 · I'm using an LoLin ESP8266 NodeMcu V3. I need a second UART port for communicating with a device over an RS232/UART converter. I want to keep the embedded UART/USB for programming/debug purpose.

Nov 10, 2016 · I recentry started exploring the world of ESP8266. NodeMCU is great, but delivering lua code to esp is a pain. I want to start new project – online IDE which will be able to update code on one or group of devices. What do you think of it? This tool will hel you to. edit end deploy code over the internet, no uart required

Jul 27, 2016 · One of them, I used to follow Neil Kolban's video tutorial on programming. Unfortunately, I bricked the device. So, I went to NodeMCU.com and downloaded the latest release of their firmware. I have that loaded and it does come up stating: NodeMCU 1.5.1 build unspecified powered by Lua 5.1.4 on SDK 1.5.1(e67da894) lua: cannot open init.lua

- Thu May 07, 2015 2:44 am #16752 If you build up some 3d models I would be happy to add them to the kicad-ESP8266 library. Other modules are also welcome. The best way to get them to me is as a pull request or an issue on github.
