1. Introduction
EdgeBox-RPI4 is a rugged fanless Edge Computing Controller with Raspberry Pi Computer Module 4(CM4)
for harsh industry environment.It can be used to connect the field networks with cloud or IoT applications. It is
designed from the ground up to meet the challenges of rugged applications at competitive prices,ideal for small
business or small order with scale milti-level demands.
1.1 Features
State-of-the-art Aluminium chassis for Harsh environment
Integrated passive heat sink
Built-in mini PCIe socket for RF module, such as 4G, WI-FI, Lora or Zigbee
SMA antenna holes x2
Built in UPS with supercap for safe shutdown
Encryption chip ATECC608A
Hardware Watchdog
RTC with Super Capacitor
Isolated DI&DO terminal
35mm DIN Rail support
Wide power supply from 9 to 36V DC
These features make the EdgeBox-RPI4 designed for easy setup and quick deployment for typical
industrial applications, such as status monitoring, facility management,digital signage and remote control of
public utilities.Furthermore, it is a user-friendly gateway solution with 4 cores ARM Cortex A72 and most
industry protocols can save on total deployment costs including electrical power cabling cost and help reduce
the product’s deployment time. Its ultra-lightweight and compact design is the answer for applications in
space-constricting environments ensures it can operate reliably in a variety of extreme environments
including in-vehicle applications.
