Power Input¶
The PPC-CM4-150 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 figure 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.

Touch Screen¶
The PPC-CM4-150 industrial Pi PC uses a 10-point capacitive touch with 1mm Armored Glass screen. However, the Raspberry Pi OS supports only One-Point touch.
The figure 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 float 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-CM4-150 Power Input connector (pin 3) is properly connected to the Power System Ground to provide sufficient EMI shielding and eliminate the problem entirely.
Bad GND problems can also be confirmed 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-CM4-150 industrial Pi PC. It has 2 x USB 3.0 Host, 1 x USB OTG, 1 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 phoenix terminal, as illustrated in the figure below.
RS232-RS485-CAN on the PPC-CM4-150 Industrial PC
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.
The 2 x RS485 can be configured to 2 x RS232, if you want a custom configuration, you can contact us when placing an order.

GPIO Port¶
The PPC-CM4-150 industrial Pi PC has a phoenix connector, as shown in the figure below. The table below gives details about the definition of every Pin.
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, has been added to limit the input current, as shown in the figure below. 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 reduced schematic is for reference purpose, if you need the precise resistor schematic, please contact us.

USB Connectors¶
There are 2 x USB 3.0 Host, 1 x USB OTG onboard, as shown in the figure below.
USB HOST Connectors
Attention
1. These two USB host connectors can drive 500mA for each channel at most.
The product has one USB Type-C OTG connector that works as a slave by default. You can use it to establish a connection with the host PC and for downloading the system to the eMMC of CM4 module.
USB Type-C OTG Connector
Warning
Be careful not to touch surrounding electronic components accidentally while plugging in USB devices into the embedded Industrial PC version.
Remember to unplug the Type-C cable after flashing OS, otherwise the USB hosts won’t work.
LAN¶
The 1 x Giga LAN provides Ethernet connectivity over standardized Ethernet cables as shown in the figure below. The integrated Ethernet interface supports up to 1 Gbps data throughput. These Giga LAN signals come from the CM4 module directly.
RJ45 LAN Connector
Note
Use CAT5 or better cables to achieve full data throughput over maximum distance defined by the 1000BASE-T standard (100m).
WiFi & BT Module¶
The default PPC-CM4-150 without the CM4 does not include a Wi-Fi/BT module.
If you include a CM4 that has the Wi-Fi/BT module, the product will have Wi-Fi/BT feature.
The enclosed (CS10768RA4150P) variant of the product also includes an SMA connector for an external WiFi/BT antenna, as illustrated in the figure below.
WiFi+BT Antenna
Attention
The product does not come shipped with the Wi-Fi/BT module by default.
3G/4G/LTE Module¶
The PPC-CM4-150 industrial Pi PC is equipped with a mini-PCIe connector that can connect to a 3G/4G/LTE module. The customer will also need a SIM Card Holder and a 3G/4G/LTE antenna to ensure 3G/4G/LTE works on the PPC-CM4-150. SIM card does NOT support hot plug. Power off before inserting or removing SIM card.
