ComfilePi Industrial Touch Panel PCs are Based on Raspberry Pi CM3 Module

ComfilePi CPi-A070WR & CPi-A102WR are industrial IP65 panel PCs powered by Raspberry Pi CM3 compute module, with respectively 7″ and 10.2″ resistive touchscreen displays, and that run modified version of Raspbian OS.

ComfilePi CPi touch panel computers specifications:

  • SoC – Broadcom BMC2837 quad core Cortex A53 processor @ up to 1.2GHz with Broadcom VideoCore IV GPU
  • System Memory – 1 GB
  • Storage – 1x micro SD Slot
  • Display
    • 7“ 800×480 Touchscreen Pressure-sensitive (Resistive Film Type) LCD display OR
    • 10.2” 800×480 Touchscreen Pressure-sensitive (Resistive Film Type) LCD display
  • Audio – 3.5mm audio out port
  • I/Os
    • 40-pin header socket based on Raspberry Pi 40-pin header pinout with 22x GPIO with ESD protection circuit
    • 2x RS-232 terminal blocks
    • 1x I2C terminal block
  • USB – 3x USB 2.0 ports
  • Connectivity – 10/100M Ethernet, optional WiFi via USB dongle
  • Misc – 1x Piezzo buzzer
  • Power Supply – 12~24V DC via 3-pin terminal block
  • Dimensions (housing made of Flame retardant ABS)
    • CPi-A070WR – 187 x 124 x 51.1 mm
    • CPi-A102WR – 264 x 70 x 52.6 mm
  • Temperature range – Operating: 0°C to 70°C; storage – -20°C to 80°C
  • IP Rating – IP65 rated front panel

While the company mentions CM3 module, it appears they actually went with CM3L module, an odd choice for an industrial product, as it means the OS will run from micro SD card, instead of the more reliable / resistant to vibrations eMMC flash found in CM3 module.

The company provides a Raspbian image for the touch panel PC that’s modified for:

  • Legal reasons – Removed Mathematica and the Wolfram Language, the Oracle JDK, and RealVNC since they are not allowed in commercial products (without paying extra)
  • User Interface Framework – Qt 5.8 and supporting packages added
  • Features specific to ComfilePi Panel PC – Touchscreen calibration, and piezzo buzzer beep when touch is detected

Source code can be found in the FTP server, and you’ll find hardware and software documentation in the Wiki. The video below provides an overview and demonstrates a few use cases for the panel PCs.

ComfilePi CPi-A070W & CPi-A102WR industrial panel PCs are sold for respectively $199 & $299 on Comfile Tech website, but you’ll also find both models on US based Saelig distributor for bit more.
