3

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.

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 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.

../../../../../_images/TS_CON3.jpeg

Figure 850: 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.

Attention

  1. RS485_3 and RS232_3 share the same channel UART3, so they cannot be used at the same time.

  2. RS485_5 and RS232_5 share the same channel UART5, so they cannot be used at the same time.

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

  4. The 120Ω match resistor for the RS232 and CAN bus is NOT mounted by default.

GPIO Port

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

Figure 853: 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.

../../../../../_images/CM3-70-USB.jpeg

Figure 854: 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.

../../../../../_images/OTG_V2.jpg

Warning

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

LAN Connectors

LAN (RJ45) connector provides Ethernet connectivity over standardized Ethernet cables as shown the figure below. The integrated Ethernet interface supports up to 1 Gbps data throughput. These Giga LAN signals come from the CM4 module directly.

../../../../../_images/LAN5.jpeg

Figure 856: RJ45 LAN Connectors (embedded/enclosed PC version)

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 EPC/PPC-CM4-070 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) variant of the product also includes an SMA connector for an external WiFi/BT antenna, as illustrated in the figure below.

../../../../../_images/Antenna6.jpeg

Figure 857: WiFi+BT Antenna

Attention

The product does not come shipped with the Wi-Fi/BT module by default.

3G/4G/LTE Module

The EPC/PPC-CM4-070 industrial Pi PC is equipped with a mini-PCIe connector that can connect to a 3G/4G module. The customer will also need a SIM Card Holder and a 3G/4G Antenna Connector to ensure 3G/4G works on the EPC/PPC-CM4-070.

../../../../../_images/TF_Card5.jpeg

Figure 863: TF (micro SD) Card Slot

Attention

  1. The SD0 is used only for the Lite version of Compute Module 4 that has no internal eMMC. If you use CM4 with eMMC, this SD0 will be disabled.

  2. The SD1 is used for memory extension. It can’t be used for system boot-up.

  3. The product does not come shipped with the TF Card by default.

Audio Connectors

The EPC/PPC-CM4-070 industrial Pi PC features some audio peripherals. It has 1 x 3.5mm audio output jack.
Also, the EPC/PPC-CM4-070 industrial Pi PC has a miniature 2W internal speaker for audio reproduction, as well as a small buzzer for alarm/notification sounds.

../../../../../_images/Headphone_V2.jpg

Attention

By plugging in the headphone cable, the internal speaker will be disabled automatically.

Boot Button Switch

The EPC/PPC-CM4-070 industrial Pi PC has one switch on the board marked as SW1, shown in the figure below.
When press the button before power on, the Raspberry Pi will boot from the USB connector. You can use this function to download the OS software to the internal eMMC.
When release the button before power on, or ignore the button when you power, the Raspberry Pi will boot from internal eMMC.

There is no need to alter the Button switch settings during regular operation. However, if you need to reinstall the OS, please refer to the detailed information on how to re-flash the OS from the Software Documentation.
