ATM…

It is available both as an embedded solution and as a device hosed in a casing with bezels,

thus facilitating dierent installation options:

Installation on an industrial cabinet

Integration with the existing equipment

The EPC/PPC-CM4-050 industrial Pi PC is based around the powerful Raspberry Pi

Compute Module 4, powered by the Quad Cortex -A72 processor with a processor speed of

1.5GHz.

Ordering Options

Chipsee products can be customized during the ordering process. The product will be

shipped with the pre-installed factory defaults if no extra requirements are specied. The

table in the Specications section provides information about the default options bundled

with the product.

EPC/PPC-CM4-050 Product Overview

Chipsee IPC Page 7 of 20

Pi CM4 Module

The Pi Compute Module 4 appears in dierent versions depending on the size of the DDR4

and eMMC.

The EPC/PPC-CM4-050 industrial Pi PC does not include the CM4 Raspberry Pi module by

default. If you would like to purchase it with a CM4, you can select it at the Chipsee store

during the ordering process.

Operating System

This product comes with a pre-installed Debian OS. Chipsee software engineers have

created all the drivers, so every hardware feature is readily available for any standard

development tool.

If your project requires a dierent OS, please Contact us, and we’ll make a customized

version that suits your needs.

Specifications

The EPC/PPC-CM4-050 industrial Pi PC oers a broad range of performance and connectivity

options for scalable integration, providing expandability according to future needs. Some of

the key features are listed in the table below.

The RS485 circuit controls the Input and Output direction automatically, there’s no need to control it from

within the software.

The default product without the CM4 does not include a Wi-Fi/BT module. You can include a CM4 that has the

Wi-Fi/BT module at the Chipsee store during the ordering process.

Chipsee designed TF card slots for storage expansion, as the TF card for storage expansion use same pins with

WiFi, it can’t be used with WiFi at same time

Power Input

The EPC/PPC-CM4-050 industrial Pi PC can be powered by a wide range of input voltages:

From 9V to 36V DC. It is a 3 Pin, 3.81mm screw terminal connector. The polarity and the

pinout is clearly marked on the housing of the CS12720RA4050P version, as shown in the

gures below.

Figure 966: Power Input

Note that the “+” sign represents the positive power input, and it is printed both at the

casing and as a silk-screen on the board of the embedded version. The “-” terminal is

shorted to the ground.

Touch Screen

The EPC/PPC-CM4-050 industrial Pi PC uses a 5-point capacitive touch screen. However, the

Debian OS supports only One-Point touch.

The gure below shows the capacitive touch screen connected to the motherboard via the

FPC connector.
