Description

The Iono Pi board adds several digital and analog input lines, power relay outputs, support for standard interfaces like 1-Wire and Wiegand typical of a modern PLC to the Raspberry Pi.

This add-on board is the the core of our Iono Pi module and Iono Pi Touch Display and can be purchased separately for product evaluation, prototypes developments, or custom embedded designs.

Features

Mounting:

  • standard Raspberry Pi 40-pin GPIO header
  • power supply and I/O connections on screw terminal block
