README
README.mdatu100wifi
This is a little extension device for David Fainitski's ATU-100 antenna tuner. It adds connectivity though wifi to use the tuner in a remote setup. The software publishes all measurement data using MQTT and accepts remote commands through another MQTT topic.
The device replaces the tuner's display. It communicates with the ATU-100 through it's I2C bus to grasp all the measurement data. An Arduino Nano acts as I2C slave, listening with the display's address, and interpreting the rendering commands coming from the ATU-100. The Nano sends the display content to an ESP8266 WeMos D1 mini, where the data is parsed, packed into a JSON object and published to a MQTT topic.
This project uses PlatformIO to build the software for the MCUs.
Disclaimer
I develop this device for myself and just for fun in my free time. If you find it useful, I'm happy to hear about that. If you have trouble using it, you have all the source code to fix the problem yourself (although pull requests are welcome).
I am not liable for whatever happens to you by building or using this device. Do this on your own risk!

Questions
How big is the Atu100wifi PCB?
It measures 83.8 × 120.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Atu100wifi use?
31 parts, built around the WEMOS D1 MINI, LTV-847 and ULN2004A. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Atu100wifi KiCad files?
From the ftl/atu100wifi repository on GitHub, at the commit this page was made from: the board is kicad/kicad.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Atu100wifi design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
