Raspberry Pi CM4 Panel PCs offer IP67 protection, 7-inch display

We just have covered Raspberry Pi CM4 in CutiePi 8-inch tablet, but I don’t think I’ve seen the latest Raspberry Pi Compute Module inside a panel PC that typically offers additional interfaces such as Ethernet, RS232, or CAN bus for industrial applications.

But today I’m here to write not about just one Raspberry Pi CM4 panel PC, but two from Chipsee and WIN Enterprises all with a 7-inch display, and features like Ethernet, opto-isolated GPIOs, RS485 terminal blocks, etc…, and the Win Enterprises’ model also adds dust and waterproofness with IP67 ingress protection rating.

    WIN Enterprises PL-50300
    Waterproof connectors

    The company only mentioned Ubuntu operating systems and provides optional DIN-rail mounting for the panel PC.

    The use of Raspberry Pi Compute Module 4 is not explicitly specified, as only Broadcom BCM2711 is listed in the specifications, but as LinuxGizmos points out the design most probably relies on the CM4 plus a custom carrier board instead of a Raspberry Pi 4 SBC.

WIN Enterprises did not provide pricing nor availability information for the panel PC. More details may be found on PL-50300 product page.
