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.

Pi CM4 Module

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

and eMMC.

The PPC-CM4-121 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.

Optional Features

The PPC-CM4-121 industrial Pi PC does not include the 3G/4G/LTE modules by default.

These modules are optional and can be selected at the Chipsee store during the ordering

process.

Note

You can order PPC-CM4-121 from the ocial Chipsee Store or from your nearest distributor.



Warning

Installation, repair, and maintenance tasks should be performed by trained personnel only.

Chipsee does not bear any responsibility for damage caused by inadequate handling of the product.

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.

This TF card is designed for storage expansion, as the TF card uses the same pins with WiFi, it can’t be used

with WiFi at the same time

Power Input

The PPC-CM4-121 industrial Pi PC can be powered by a wide range of input voltages: From

12V to 36V DC. It is a 3 Pin, 3.81mm screw terminal connector. As shown in the gure

below.

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.

Power Input Denition

Pin Number Denition Description

Pin 1 Positive Input DC Power Positive Terminal

Pin 2 Negative Input DC Power Negative Terminal

Pin 3 Ground Power System Ground

Table 260 Power Connector

Note

The system ground “G” is connected to power negative “-” on board.

Touch Screen

The PPC-CM4-121 industrial Pi PC uses a 10-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

USB connector.

Capacitive Touch Connector

Attention

A capacitive touch screen is susceptible to power noise and Electromagnetic Radiation (EMR). It may cause LCD ripples

or even capacitive touch malfunction. If using a capacitive multi-touch test application, you might notice the touch

points oat erratically across the display. There are several solutions to this problem:

Use a high-quality Power Adapter Unit (PSU) with low EMR. You can also provide power from a battery.

Make sure that the PPC-CM4-121 Power Input connector (pin 3) is properly connected to the Power System

Ground to provide sucient EMI shielding and eliminate the problem entirely.

Bad GND problems can also be conrmed by touching pin 3 of the Power Input connector with one hand while

operating the capacitive touch screen with the other hand. In this case, the operator’s body acts as the Power

System Ground.
