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.

Chipsee CM4-70 Industrial Pi 7-inch Panel PC

Chipsee Industrial Pi CM4-70-EM panel pc — Embedded Version

Chipsee panel PC is offered in two versions with CM4-70-EM model meant to be integrated into the customer’s own chassis, and CM4-70-PA integrating the board and display into a fully assembled panel.

Power Consumption – 5W (12V @ 420 mA max)
Dimensions & Weight
- Embedded: 190 × 107.8 × 27.7 mm, 400 grams
- Panel: 190 × 107.8 × 27.7 mm (something’s not right here…), 700 grams
Temperature Range – 0°C to 50°C

Chipsee CM4-70-PA panel pc — CM4-70-PA Panel PC

The company says the panel PC support Debian 10 (meaning Raspberry Pi OS here), and Ubuntu operating systems.

Chipsee Industrial Pi CM4-70-EM is sold for $199, while CM4-70-PA goes for $219 with the optional 4G LTE module plus antenna adding $64 for either model.

WIN Enterprises PL-50300 IP67 Panel PC

WIN Enterprises PL-50300 is also a 7-inch panel PC powered by Raspberry Pi CM4, but with a different set of features and ports:

SoM – Raspberry Pi Compute Module 4 (CM4) with Broadcom BCM2711 quad-core Cortex-A72 processor, 2 to 8GB RAM
Storage – MicroSD card slot
Display – 7-inch 800×480 color LCD with a 10-point capacitive touchscreen
Networking
- Gigabit Ethernet port (IP67)
- Optional dual-band 802.11b/g/n/ac WiFI 5 and/or Bluetooth 5.0 LE
- Optional 4G cellular + GPS module
USB – 2x USB 3.0 ports (IP67), and internal USB 2.0 interfaces
Serial – RS485 half-duplex port (IP67)
Expansion – 40-pin GPIO header
Power Supply – 12V/3A via IP67 connector
Dimensions – 282.89 x 145.87 x 55.31mm (Die-cast aluminum chassis)
Temperature Range – Base model: 0 to 50°C; extended: -20 to 85°C
Certifications – CE, FCC class A, NEMA 4x, IP67 rating
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.
