The first way is to connect the board to the breadboard using female to male Dupont cables. If you are lucky (or smart) enough to have purchased a NodeMCU v1.0 board, you can skip this section, but if you are stuck with NodeMCU v0.9 this may be useful. NodeMCU v1.0 Pinout NodeMCU v0.9 Pinout (Click to Enlarge) Using NodeMCU v0.9 with a Breadboard We’ll use these a little later in this tutorial. Please find the pinout for both versions below. Other differences are that NodeMCU v1.0 has some extra GPIOs. The image was still v0.9, but since there are only two version, I was sort of expecting to receive NodeMCU v1.0. I’ve bought mine for just above $6 on eBay advertised as “NEW Version NodeMcu Lua ESP8266 WIFI Internet Development Board Latest Firmware”.

The main complain about NodeMCU v0.9 is that while it fits on the breadboard, you can’t use as it takes the full width of the board, while NodeMCU v1.0 is really breadboard-friendly as you can see on the right part of the picture above. NodeMCU v0.9 vs NodeMCU v1.0 (Click to Enlarge) If you are going to purchase a NodeMCU board it’s important to know there are two official versions: I also noticed a ESP8266 tutorial with NodeMCU firmware by SwitchDoc Labs the other day (using ESP-12 and Adafruit Huzzah), which I applied to my NodeMCU board, but since I encountered a few issues, I decided to report my findings, and write my own little getting started guide to switch on/off LED and GPIOs using a web interface.

I selected this board because the latest version of the board is breadboard-friendly, integrates a USB to serial chip, and it can be powered by a simple USB to micro USB cable. Please change “n” with the appropriate starting address for your device on the list (it starts with 100).Since ESP8266 is now so popular, I’ve recently bought a NodeMCU board to try it. The picture below shows a generic pin mapping on a NodeMCU board (which is the most popular ESP8266 board). On the device itself, each located variable maps to a corresponding pin. Below you can see a list of three ESP8266 devices added up together, and the respective address space reserved for them. OpenPLC supports multiple slave devices at the same time, and they all add up together on the address space.
The pin mapping for your ESP8266 depends on its position on the slave devices list. Everything else should be filled up automatically for you.Ĭlick on “Save device” and you’re good to go! Just start the PLC and your board will be communicating over WiFi with OpenPLC Runtime. On the new screen that appears, fill out the name for your slave device (it can be anything, but just please avoid non-English characters like ç, é, ó, ñ), select ESP8266 under Device Type and type in the ESP8266 IP address that you got from the previous step.
Web interface, go to Slave Devices on the menu and click on “Add new device”. Launch OpenPLC Runtime on your host, log in on the Add A Slave Device to OpenPLCĪfter programming your ESP8266 with OpenPLC’s firmware, you now need to add Write down the IP address on that message because you will need to use it on the next step. “Additional Board Manager URLs” text box: Open up Arduino IDE, then go to the Preferences (File > Preferences)Īnd then, towards the bottom of the window, copy this URL into the Setup your Arduino IDE to program ESP8266 devices (if you haven’t done itĪlready). This is probably theĮasiest platform to program the ESP8266. The ESP8266 firmware was written using the Arduino IDE. Page to have it installed and then move to the next step. You can use any of the listedĭevices on the Getting Started page as a host. Runtime installed on your system to proceed.
Given that ESP8266 boards can only work as slave devices, the first thing you

This is particularly useful for systems that don’t haveĪny I/O points at all (in case of OpenPLC running on Windows for example). You can attach ESP8266 boards as wireless slave devices to expand the number
