5G IoT/AIoT industrial gateway ships with Raspberry Pi Compute Module 4

WPC-632-Pi CM4 is an industrial IoT gateway based on Raspberry Pi Compute Module 4 with optional 5G or 4G LTE cellular connectivity, that joins other Raspberry Pi CM4 industrial gateways such as CompuLab IOT-GATE-RPI4, CatsPi Industrial Lite, Modberry M500 CM4, among others.

The Linux gateway features two Ethernet ports, RS232/RS485 and other I/Os via terminal blocks, mPCIe and M.2 sockets for expansion with 5G modem 4G LTE mode, AI accelerator, or an NVMe SSD, as well as support for 9V to 32V wide-range input power.

• Misc – RTC with battery, buzzer, watchdog timer, reset button, 12V header for fan, various LEDs for power, storage, serial, I/O, networking…
• Power Supply – 9V-32V DC, 1000mA @ 12V via DC jack or terminal block
• Dimensions – 170 x 110 x 30 mm (metal housing)
• Weight – 950 grams
• Temperature Range – Operating: -20°C to +75°C; storage: -25°C to +80°C

Two models are apparently offered with WPC-632-PI CM4-B (for M.2 KEY B) and WPC-632-PI CM4-M (for M.2 KEY M)  depending on whether you need to add 5G or NVMe storage to the gateway. There’s no information about software, but I’d assume the gateway runs Raspberry Pi OS plus possibly some drivers for wireless modules and I/Os.

It took me a while to figure out who the manufacturer was. I first found it on TechDesign saying the manufacturer was “Artisantech Computer Engineering Co. Ltd”, but I also noticed WPC-632 “Industrial IoT gateway” on tcpipweb website for KSH International. Since information online was limited, I ended up asking for additional info from the latter, and they sent a few documents including CE and FCC “verification of compliance” certificates with the name of the company, so I believe KSH International is indeed the manufacturer.

[Update Jan 10,2022: I received more clarifications about the relationship between companies involved in the product. “KSH produces the hardware which Artisantech then adds software onto to create solutions which are ready to use by customers.”]

Applications for the IoT gateway include 5G enterprise networks, IoT data acquisition, environment monitoring, smart office/building, industry 4.0 applications, unmanned base station monitor, and more. WPC-632-Pi CM4 gateway is available now, but as usual for this type of hardware, pricing has not been made public.
