Maybe some day in the past you wanted to explore what these mysterious PLCs are. How do you program them? How are they interconnected? How you control a robot arm with it?

...and then you saw the >>$200 price tag for just one simple module and decided to stay with your beloved Arduino or ESP.

PeaLC is here for you. You can take your stock ESP32 and make it behave like these overpriced industrial beasts. You can learn, experiment, even build a demo industrial line in your living room. Because we can!

PeaLC is programmed using standard IEC 61131-3 ladder logic (thanks to Matiec compiler and OpenPLC core library), so you can also prototype your automated gardening system and then easily port it to the real, commercial PLC.
