In mid-October 2020, the Industrial Raspberry Pi family has added a new and more powerful member: RevPi Compact.
RevPi Compact is a powerful, compact controller, and its price is more advantageous. It is based on the Raspberry Pi computing module 3+, with more diverse connection options and functions.

RevPi Compact has 8 digital and analog inputs, 8 digital outputs and 2 analog outputs, which can be connected to your sensors and actuators. With the help of two Ethernet interfaces with independent MAC addresses, RevPi Compact has the ability to integrate two different networks. In addition, it also integrates 4 USB type A interfaces and 1 4-pin RS485 interface.
The detailed interface information is shown in the following table:
| interface |
|---|
| 2x RJ45 10/100 Ethernet (with independent MAC address) |
| 4x USB A (the maximum total current of all sockets is 2A) |
| 1x HDMI socket |
| 1x Micro-USB (only used to burn the image to eMMC) |
| 1x RS485 max.500 kbps, terminal can be switched by software (non-electrically isolated) |
| 8x digital input input threshold: Compatible with EN 61131-2 Type I and Type III sensors at 24 V DC |
| 8x digital output high end with 10k pull-down resistor, short circuit protection (internal temperature cut off), potential separation system/digital output. Maximum current load: each output: 500 mA @ 24 V DC (resistive load). Sum of all outputs: max 2 A @ 24 V DC (resistive load) |
| 8x analog input 0-10 VDC, single-ended, 16Bit for piControl, original value 21Bit, software switchable current source 2.5mA |
| 2x analog output 0-10 V, short circuit protection, feedback protection, 8Bit resolution accuracy of 1%, maximum current load 10mA (10VDC@1k) |
Like other products in the RevPi family, RevPi Compact is designed to follow the concept of open source, allowing users to implement their projects with the greatest degree of freedom. The flat design allows the device to be installed in the sub-distribution system common in building automation.
RevPi Compact is also configured via the pre-installed browser application PiCtory. The operating system is a customized version of Raspbain with real-time patches. Users can write their own applications through Node-RED, Python or directly in C.
RevPi Compact supports the common industrial protocols Modbus RTU and Modbus TCP by default. It also supports ready-made professional software solutions, such as Codesys and logi.CAD.
