Overview
This is an industrial expansion module based on Raspberry Pi CM4, which features common interfaces such as Gigabit Ethernet, HDMI, USB, and GPIO, allowing additional 4G / 5G / LoRa wireless communication modules to be connected via the M.2 or Mini-PCIe socket. There are also industrial interfaces/resources including RS485, CAN, and RTC.
Combined with the industrial rail-mount protection case, the module is an ideal choice for building an IoT gateway, 4G/5G router, IoT data acquisition, or even the PLC device in the industrial automatic control system, and more.
Notices
1. DO NOT hot-plug any devices except the USB and HDMI.
2. Please check the FAN voltage before connecting the cooling fan. The BASE board supports a 12V cooling fan by default, if you want to use a 5V cooling fan, please change the FAN_VCC resistor.
3. DO NOT connect other devices while writing CM4 via the Type C interface for stable working.
4. 5V/2.5A or higher power supply is recommended for proper working.
5. DO NOT power the Base board by 12V DC and the 5V Type C at the same time.
6. The USB2.0 is disabled by default, you need to add the line dtoverlay=dwc2,dr_mode=host to config.txt to enable it.
