Iono Pi Board
Industrial Raspberry Pi expansion board featuring digital and analog inputs, power relay outputs, open-collector outputs, and versatile I/O lines supporting I2C, 1 Wire, Wiegand, and other digital protocols. Includes a wide range power supply and Real Time Clock (RTC). Fully compliant with CE, FCC, and IC standards.
DESCRIPTION
The Iono Pi board transforms the Raspberry Pi into a powerful and versatile controller by adding a wide range of industrial grade digital and analog I/Os, power relay outputs, and support for standard communication interfaces such as 1 Wire and Wiegand features typically found in modern PLCs.
This expansion board serves as the foundation of the Iono Pi Module and the Iono Pi Touch Display, and can also be purchased separately for testing, prototyping, or integration into custom embedded projects.
