1

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

2

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.

3

Chipsee designed one TF card slot for CM4 Lite version which has no eMMC to boot OS.

Power Input

The PPC-CM4-070-D industrial Pi PC can be powered by a wide range of input voltages: From 6V 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 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.

Table 340 Power Connector

Power Input Definition
Pin Number	Definition	Description
Pin 1	Positive Input	DC Power Positive Terminal
Pin 2	Negative Input	DC Power Negative Terminal
Pin 3	Ground	Power System Ground

Note

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

There is another power input port, it is a 2.1mm x 5.5mm x 9.5mm DC jack. For a proper DC power connector, refer to the figure below.

DC Jack

Touch Screen

The PPC-CM4-070-D industrial Pi PC uses a 5-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 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 float erratically across the display. There are several solutions to this problem:

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

2. Make sure that the PPC-CM4-070-D Power Input connector (pin 3) is properly connected to the Power System Ground to provide sufficient EMI shielding and eliminate the problem entirely.

3. 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-CM4-070-D industrial Pi PC. It has 2 x USB 3.0 Host, 1 x USB Type-C OTG, 2 x Giga LAN (optional PoE support for LAN0) (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 figure below.

RS232-RS485-CAN on the PPC-CM4-070-D Industrial PC

Attention

1. RS485_3 and RS485_5 can control the input and output direction automatically. There’s no need to control it from within the software.

2. The 120Ω match resistor for RS485 is already mounted by default.

3. The 120Ω match resistor for CAN is NOT mounted by default. Be sure to mount the match resistor when testing CAN.

4. 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.

The table below offers more detailed description of every pin and its definition:

GPIO Port

The PPC-CM4-070-D industrial Pi PC has a 10 Pin 3.81mm GPIO Connector, as shown in the figure below. The table below gives details about the definition of every Pin.

Attention

1. 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.

2. The output current can achieve 500mA for every channel, but it also depends on the isolated power that is connected.

3. 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.

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 definition of CPU GPIO:

Warning

Without the optical isolation, CPU might be damanged if dangerous voltages are applied to CPU GPIO. Be careful when using CPU GPIO directly.

USB Connectors

There are 2 x USB 3.0 Host, 1 x USB Type-C 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

1. Be careful not to touch surrounding electronic components accidentally while plugging in USB devices into the embedded Industrial PC version.

2. Remember to unplug the Type-C cable after flashing OS, otherwise the USB hosts won’t work.

LAN

The 2 x Giga LAN (optional PoE support for LAN0) 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-CM4-070-D 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 (CS10600RA4070P-D) variant of the product also includes an SMA connector for an external WiFi/BT antenna, as illustrated in the figure below.
