Power Input
The PPC-CM4-070-D industrial Pi PC can be powered by a wide range of input voltages:
From 9V to 36V DC. There are two types of power input connectors. One is a 3 Pin, 3.81mm
screw terminal connector, and the other is a 2.1mm DC input head. 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.

Pin 2 Negative Input DC Power Negative Terminal
Pin 3 Ground Power System Ground

Touch Screen
The PPC-CM4-070-D 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.
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-CM4-070-D 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.

Connectivity
There are many connectivity options available on the PPC-CM4-070-D industrial Pi PC. It has
2 x USB 3.0 Host, 1 x USB Type-C OTG, 2 x Giga LAN (RJ45) Ethernet connector supporting up
to 1 Gbps, and 4 x UART and 1 x CAN terminals (RS232/RS485/CAN).
RS232/RS485/CAN
The serial communication interfaces (RS485, RS232, and CAN) are routed to a 16-pin
3.81mm terminal, as illustrated in the gure below.
RS232-RS485-CAN on the PPC-CM4-070-D Industrial PC
The table below oers more detailed description of every pin and its denition:
Attention
RS485_3 and RS485_5 can control the input and output direction automatically. There’s no need to control it from
within the software.
The 120Ω match resistor for RS485 is already mounted by default.
The 120Ω match resistor for CAN is NOT mounted by default. Be sure to mount the match resistor when testing
CAN.
RS485_3 and RS232_3 share UART3 and can’t work at the same time; RS485_5 and RS232_5 share UART5 and can’t
work at the same time. Meaning the product provides 4 x RS232 + 0 x RS485, or 2 x RS232 + 2 x RS485, or 3 x
RS232 + 1 x RS485.

Pin 2 GND System Ground
Pin 1 +5V System +5V Power Output, No more than 1A Current output
Table 251 Connectivity Section
Attention
In order to use the Isolated Output, you need to add an external Isolated Power to the VDD_ISO and GND_ISO.
The power voltage should not exceed 24V.
The output current can achieve 500mA for every channel, but it also depends on the isolated power that is
connected.
In order to use the Isolated Input, you need to add a signal to the ISO_InputX and GND_ISO. A 2.4KΩ resistor, as
R6, can be added to limit the input current, as shown in the gure above. This resistor should work well for the
5-24V input signal. If your input signal is less than 5V, please change this input resistor.

The PPC-CM4-070-D also supports GPIO routed from the Raspberry Pi CM4 CPU directly, if
you choose to use the 6 channel CPU GPIO, instead of 8 channel optical isolated GPIO, you
can take advantage of the community software libraries of Pi GPIO. If you choose to use
CPU GPIO, you won’t be able to use the 8 channel optical isolated GPIO. Below is the pin
