Power Input Connector

The product CS10600RA4070E/CS10600RA4070P uses a wide-range power input DC 6~36V. The total power consumption is normally about 5W. There are two types of power input interface onboard. One is a 3 Pin 3.81mm screw terminal connector, as shown in Figure 5. The other is the 2.1mmDC input head, as shown in figure 6. A detailed description of the power input connector pins is provided in Table 1

Figure 5: 3 Pin 3.81mm Screw Terminal Connector

Figure 6: 2.1mm DC input head

Table 1

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


The system ground “GND” has been connected to power negative “-” on board.
The central pin is positive. 

CAN+RS485+RS232 Connector

The RS485+RS232+CAN connector is a 16 Pin 3.81mm screw terminal connector, as Figure 7 shows. As for the definition of every pin, please refer to Table 2.

Figure 7: RS485+RS232+CAN Connector

Table 2

RS232 / RS485 Pin Definition:
Pin Number Definition Description
Pin 16 CAN_H CAN BUS “H” signal
Pin 15 CAN_L CAN BUS “L” signal
Pin 14 RS485_5- CPU UART5, RS485 –(B) signal
Pin 13 RS485_5+ CPU UART5, RS485 +(A) signal
Pin 12 RS232_5_RXD CPU UART5, RS232 RXD signal
Pin 11 RS232_5_TXD CPU UART5, RS232 TXD signal
Pin 10 RS485_3- CPU UART3, RS485 –(B) signal
Pin 9 RS485_3+ CPU UART3, RS485 +(A) signal
Pin 8 RS232_3_RXD CPU UART3, RS232 RXD signal
Pin 7 RS232_3_TXD CPU UART3, RS232 TXD signal
Pin 6 RS232_2_RXD CPU UART2, RS232 RXD signal
Pin 5 RS232_2_TXD CPU UART2, RS232 TXD signal
Pin 4 RS232_0_RXD CPU UART0, RS232 RXD signal
Pin 3 RS232_0_TXD CPU UART0, RS232 TXD signal
Pin 2 GND System Ground
Pin 1 +5V System +5V Power Output, No more than 1A Current output.

(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 Connector

There is a GPIO interface as shown in Figure 8.
As for the definition of every pin, please refer to Table 3.

Figure 8: GPIO Connector

Table 3

RS232 / RS485 Pin Definition:
Pin Number Define
Pin 1 IN4
Pin 2 IN3
Pin 3 IN2
Pin 4 IN1
Pin 5 OUT4
Pin 6 OUT3
Pin 7 OUT2
Pin 8 OUT1
Pin 9 GND_ISO, Isolated Ground
Pin 10 VDD_ISO, Isolated Power Input

Figure 9: Isolated GPIO reduced schematic

(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 in Figure 9, has been added to limit the input current. This resistor should work well for the 5-24V input signal. If your input signal is less than 5V, please change this input resistor.

Capacitive Touch

The product CS10600RA4070E/CS10600RA4070P uses Five-Point capacitive touch, as Figure 10 shows. However, the Debian OS supports only One-Point touch.

Figure 10: Capacitive Touch Connector

The capacitive touch panel is very sensitive to the power adapter system noise. Please use a high-quality power adapter.  It is also recommended to connect the product power connector “G” pin to your AC system Ground.

USB HOST Connector

The product CS10600RA4070E/CS10600RA4070P has two USB2.0 HOST connectors as Figure 11 shows.

Figure 11: USB HOST Connector

(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 connecting this product to the HOST PC by a mini USB cable, the USB HUB will be disabled, so these 2 USB host connectors Zigbee and 4G/LTE will not work. 

Mini USB Connector

There is one Mini USB port, as shown in Figure 12, that is used to download the system to the eMMC of the CM4 module.

Figure 12: Mini USB Connector

LAN Connector

There’s also one channel 1000Mbit Ethernet connector, as Figure 11 shows. These Giga LAN signals come from the CM4 module directly.

Figure 13: LAN Connector

Audio Output Connector

The product CS10600RA4070E/CS10600RA4070P has one audio output, as Figure 14 shows, as well as an internal 2W speaker.

Figure 14: Audio Connector

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

TF Card

The product CS10600RA4070E/CS10600RA4070P has two TF (uSD) card connectors, as Figure 15 shows. Each supports a TF (uSD) card up to 32GB.

Figure 15: TF Card Connector

(1) The SD0 is only used for the CM4 Lite version which has no onboard 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 TF card doesn’t come with the product by default.

BOOT Switch

There is a boot switch, marked as SW1 on the silkscreen. A toggle switch can change the boot sequence.  The booth switch has two positions USB and eMMC. When in the USB position, the Raspberry Pi will boot from the USB connector. This function is used to download the software to the internal eMMC. When in the eMMC position, the Raspberry Pi will boot from internal eMMC.

Figure 16: Boot Switch

SIM Card Holder

There is a mini-PCIe connector inside the CS10600RA4070E/CS10600RA4070P that can be used to mount a 4G module. If you want to add the 4G module, then you will need the SIM card holder, as shown in Figure 18. There is a connector on the backside of the case used to connect an external 4G antenna shown in Figure 19.
