The RevPi Compact is an open
source compact control system
based on the Raspberry Pi 3+
Compute Module. The open
platform concept (including
full root rights) allows the user
maximum design freedom
in the implementation of his
projects.

To connect sensors and
actuators, the RevPi Com-

pact is equipped with eight
digital and analog inputs each
as well as eight digital and
two analog outputs. In ad­dition, the device has also a
4-pole RS485 interface with
screw terminals. Two Ethernet
interfaces (each with a sepa­rate MAC address) enable the
device to be integrated in two
dierent networks at the same
time.

The at design of the RevPi
Compact makes it possible to
install it in a subdistribution
system that is usually found in
building automation.

A customized Raspbian with
Real-Time Patch is used as
operating system. Individual
applications can be program­med via, amongst other things,

1

Paid software licenses required.

Node-RED, Python or directly in
C. The popular industrial proto­cols Modbus RTU and Modbus
TCP are supported by default.

Those who do not want to
program by themselves can
optionally use professional soft
PLC and SCADA software for
control and visualization.
