# STM32 INDUSTRIAL CONTROL BOARDS

Pin mapping for STM32 based industrial control boards advertised as compatible with FX1N, FX2N, FX3U PLC software. Usually encased in din rail mountable enclosures.

These boards are usually equipped with relay outputs, optically isolated digital inputs, RS232 serial port, 24VDC input power. Are encased in a convenient plastic, din rail compatible mount enclosure, and screw terminals for input/outputs. This is a collective effort to document pin maps for the most common types of board available on online markets, so they will be usable with different firmware and build tools, like Arduino.

## Versions

There are several board versions, each one with different personalities
