Chipsee IPC Page 5 of 25

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.

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.
