WaveShare Compute Module Industrial IoT Mini-Computer 4G PoE for Raspberry Pi CM4S/CM3/CM3+

SKU CH-4A6J-KAJR4

Industrial mini-computer adds 4G, PoE Ethernet, Wi-Fi and isolated CAN, RS-485, RS-232, ADC, GPIO and RTC to Raspberry Pi CM3/CM3+ modules

  • Industrial IoT control via isolated CAN, RS485, RS232, ADC, GPIO and RTC interfaces
  • Global 4G, 3G and 2G connectivity using the SIM7600G-H communication module
  • Power over Ethernet on a 10/100M auto-negotiation port simplifies wiring
  • Dual-band wireless not supported; 2.4GHz WiFi provides wireless fallback
  • Expand peripherals through USB hub and USB-to-UART while driving HDMI, DSI and CSI displays

Industrial IoT Mini-Computer for Raspberry Pi

This carrier board turns a Raspberry Pi Compute Module into a rugged IoT gateway. It adds global 4G connectivity via the SIM7600G-H module, 10/100M Ethernet with PoE, and 2.4 GHz WiFi. Industrial isolated interfaces include CAN, RS485, RS232, ADC, GPIO and RTC, plus HDMI, DSI and CSI ports for multimedia.

Suits remote monitoring and edge control.

Engineers building remote sensor networks, fleet trackers or industrial controllers gain cellular failover and wired industrial buses in one box. Makers needing gigabit Ethernet, 5 GHz WiFi or desktop-class expandability should consider other platforms.

10/100M PoE Ethernet decides deployment flexibility

The 10/100M auto-negotiation port with Power over Ethernet lets the unit draw power and data from a single cable, simplifying installation in cabinets or outdoor enclosures where mains sockets are scarce.

Highlights

  • Industrial IoT control via isolated CAN, RS485, RS232, ADC, GPIO and RTC interfaces
  • Global 4G, 3G and 2G connectivity using the SIM7600G-H communication module
  • Power over Ethernet on a 10/100M auto-negotiation port simplifies wiring
  • Dual-band wireless not supported; 2.4GHz WiFi provides wireless fallback
  • Expand peripherals through USB hub and USB-to-UART while driving HDMI, DSI and CSI displays

Questions about this item

Which Raspberry Pi Compute Module must I already have for this carrier board to function?

The board accepts a CM3, CM3 Lite, CM3+ or CM3+ Lite module; insert one of those to power the system.

Will the 10/100M PoE Ethernet port negotiate correctly with my older 10 Mbit switch?

Yes, the port auto-negotiates at 10 or 100 Mbit and draws power over the same cable when PoE is available.

How can I verify the SIM7600G-H 4G modem is alive after I boot the unit?

Open a serial console on the USB-to-UART port and issue AT commands; a valid response confirms the modem is registered on the 2.4 GHz mobile network.
