About PymateIO

Pymate-powered-by-micropython.png

PymateIO is an affordable Industrial Controler (PLC) Powered with MicroPython.
PymateIO is ready for Industry, Reliable, Developer-Friendly and Easy to Install.

Micro Python is an optimized version of Python 3 dedicated to embedded systems like microcontollers.
Python scripts are stored on the device and running on z bare metal Python Virtual Machine (like computer does).

PymateIO EcoSystem

PymateIO is expandable by design starting with few board, new arrivals should come with time.
