GPIO Port

The KIOSK-CM4-215 industrial Pi Kiosk has a phoenix 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.

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 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 KIOSK-CM4-215 without the CM4 does not include a Wi-Fi/BT module.

If you buy a CM4 that has the Wi-Fi/BT module, the product will have Wi-Fi/BT feature.

By default the kiosk doesn’t ship with WiFi antenna SMA, nor is there a drill hole. But if you buy the CM4 with Wi-Fi/BT module from us or contact us when placing an order, we can drill hole on the kiosk and install the antenna SMA for you.

WiFi+BT Antenna

Attention

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

3G/4G/LTE Module
