Chipsee designed one of the TF card slots for Lite version which have no eMMC. We designed the other one for storage expansion, as the TF card for storage expansion use same pins with WiFi, it can’t be used with WiFi at same time

Attention

Chipsee does not install a lithium battery by default, as we cannot ship products with batteries. We recommend you buy it locally and install it by yourself. The lithium battery part number is CR1220. Please Contact us if you need help.

Power Input

The EPC/PPC-CM4-070 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. The polarity and the pinout is clearly marked on the housing of the CS10600RA4070P version, as well as on the board itself of the CS10600RA4070E version, as shown in the figures below.

Figure 900: Power Input (embedded/enclosed version)

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 197 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.
The central pin is positive.

Touch Screen

The EPC/PPC-CM4-070 industrial Pi PC uses a 5-point capacitive touch screen. However, the Debian OS supports only One-Point touch.
The figure below shows the capacitive touch screen connected to the motherboard via the FPC connector.

Figure 901: 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 EPC/PPC-CM4-070 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 problem 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 EPC/PPC-CM4-070 industrial Pi PC. It has 2 x USB 2.0 Host, 1 x miniUSB OTG, 1 x Channel Giga LAN (RJ45) Ethernet connector supporting up to 1 Gbps, and 4 x UART terminals (RS232/RS485/CAN).

RS232/RS485/CAN

The serial communication interfaces (RS485, RS482, and CAN) are routed to a 16-pin 3.81mm terminal, as illustrated on the figure below.

Pin 3	IN2	Isolated Input 2
Pin 2	IN3	Isolated Input 3
Pin 1	IN4	Isolated Input 4

Figure 904: Isolated GPIO reduced schematic

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, can be added to limit the input current, as shown in the figure 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.

USB Connectors

There are 2 x Type A USB HOST connectors onboard, as shown on the figure below.

Figure 905: USB HOST Connectors (embedded/enclosed PC version)

Attention

1. These two USB hosts come from the same USB HUB. The Zigbee and 4G/LTE signals come from the same USB HUB.

2. These two USB host connectors can drive 500mA for each channel at most.

3. When you connect this product to the HOST PC by a mini USB cable, the USB HUB will be disabled. As a result, the 2 USB host connectors, Zigbee, and 4G/LTE will not work.

The product has one USB 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.
