Ei-U220

Industrial Raspberry Pi 4 Gateway Kit
with 1 x RS-232/485, 4 x GPIO, 1 x 8 GB
SD Card, and AdvRaspbian OSFeatures

NEW Automation kit for creating RPi-based IoT systems
 Industrial grade I/O board with RS-232/485 and GPIO for flexible expansion
 Battery-backed RTC enabling fail-safe time keeping AdvRaspbian OS enables automatic board identification and GPIO and driverconfiguration
 Easy four-step RPi 4 installation
 Supports wall and DIN rail mounting for industrial applications
 Can be equipped with TPM technology for hardware-based security uponrequestIntroduction
Ei-U220 is designed to facilitate the use of Raspberry Pi (RPi) single-board computers (SBCs) in unique IoT applications. Featuring an SD card equipped with an OS image, an RPi
4 HAT I/O board, additional RS-232/485 GPIOs, and an RTC with battery for precise time keeping, the Ei-U220 industrial-grade chassis transforms RPi 4 into an intelligent gateway.
Ei-U220 is designed with pre-finished mounting holes and attachment screws that enable plug-and-play assembly with separately purchased RPi 4 SBCs. Advantech’s Ei-U220
provides developers with a complete RPi-ready industrial-grade gateway kit ideal for rapid prototyping and mass deployment.
