A rugged, industrial-grade 8-inch capacitive touchscreen display and aluminum enclosure for Raspberry Pi 5 — built for demanding HMI applications.
The Argon Industria HMI 8CS is an industrial Human-Machine Interface (HMI) solution combining an 8-inch full optical bonding HDMI display with a precision-machined aluminum enclosure. Designed specifically for use with the Raspberry Pi 5 and the Argon Industria Base, it delivers a sharp 1280 × 800 resolution with 10-point capacitive touch in a package robust enough for factory floors, kiosks, and embedded control systems.
What sets the HMI 8CS apart from consumer display solutions is its industrial-grade construction. The full aluminum enclosure acts as a passive heatsink for the Raspberry Pi 5, drawing heat away from the board and dissipating it through the chassis without the need for a separate cooler. An optional active cooling module can be added for thermally demanding workloads. Full port access — including USB, Ethernet, HDMI, and GPIO — is maintained through the enclosure, so the system remains fully expandable even after integration.
The HMI 8CS fits naturally into the broader Argon Industria ecosystem. It supports Raspberry Pi HAT modules via the exposed 40-pin GPIO header, accepts optional M.2 NVMe expansion boards for high-speed local storage, and is compatible with Argon Industria Communication modules for fieldbus and connectivity expansion. Flexible mounting options — VESA, panel, and desktop — make it straightforward to integrate into both new builds and existing installations.

⚠️ Warning: The Raspberry Pi 5 uses micro-HDMI output connectors. The HMI 8CS display connects via a standard full-size HDMI input. You must use a micro-HDMI to HDMI cable or a micro-HDMI to HDMI adapter to make this connection. Failing to use the correct cable will result in no display output. Verify your cable or adapter before assembly.
⚠️ Warning: Handle the aluminum enclosure with care during assembly. Edges may be sharp. Inspect all machined surfaces before handling and keep hands clear of any unfinished edges.
⚠️ Warning: Always power off and disconnect the power supply before installing or removing the Raspberry Pi 5 or any expansion modules.
Before starting, confirm you have the following:
📝 Note: Detailed step-by-step instructions for installing the Raspberry Pi 5 into the Argon Industria Base are covered in the Argon Industria Base Assembly Guide.
[TODO: Provide precise fastener locations, torque specifications, and step-by-step enclosure integration procedure from
arg-ind-hmi-8cs-manual.pdf]
⚠️ Warning: Do not attempt to force a standard HDMI plug into the Raspberry Pi 5's micro-HDMI port. Use only a correctly rated micro-HDMI to HDMI cable or adapter.
If your workload is thermally demanding, the optional active cooling module can be added to the enclosure.
📝 Note: The passive aluminum enclosure is sufficient for most workloads. Add active cooling only if you observe sustained thermal throttling during operation.

The HMI 8CS works with any OS supported by the Raspberry Pi 5. Raspberry Pi OS (64-bit) is recommended for best hardware compatibility.
Flash your OS image using Raspberry Pi Imager before inserting the microSD card or NVMe drive.
The HMI 8CS display runs at 1280 × 800. If Raspberry Pi OS does not automatically detect and apply this resolution, you can set it manually by editing /boot/firmware/config.txt:
sudo nano /boot/firmware/config.txt
Add or update the following lines:
hdmi_group=2
hdmi_mode=28
📝 Note:
hdmi_group=2selects DMT (monitor) mode.hdmi_mode=28corresponds to 1280 × 800 @ 60 Hz. If this mode does not produce a stable image, consult the Raspberry Pi config.txt documentation and test adjacent mode numbers.
Save the file and reboot:
sudo reboot
The 10-point capacitive touchscreen connects via USB for touch input (HID device). On Raspberry Pi OS, the touchscreen should be detected automatically as a standard HID pointer device with no additional driver installation required.
To verify the touch device is recognized after booting:
lsusb
Look for a HID-class device corresponding to the touchscreen controller in the output.
To confirm input events are being registered:
sudo libinput debug-events
Touch the screen and verify that touch events appear in the terminal output.
📝 Note: Specific touchscreen driver packages, calibration utilities, or
.conffiles for the HMI 8CS capacitive controller are not documented in currently available sources. If touch input is not automatically detected, contact Argon 40 Support for driver guidance.
To rotate the display output (for example, for portrait orientation), add the following to /boot/firmware/config.txt:
# 0 = normal, 1 = 90°, 2 = 180°, 3 = 270°
display_rotate=0
Reboot after making changes:
sudo reboot
To monitor the Raspberry Pi 5 CPU temperature and verify the passive cooling is performing adequately:
vcgencmd measure_temp
If you observe sustained temperatures above 80 °C under load, consider adding the optional active cooling module.
If you have installed an M.2 NVMe expansion board, verify the drive is detected after booting:
lsblk
Your NVMe drive will typically appear as /dev/nvme0n1. To boot from NVMe, use Raspberry Pi Imager or rpi-eeprom-config to update the boot order. Refer to the Raspberry Pi documentation on NVMe boot for full instructions.
No image on the display after powering on
- Cause: Incorrect or missing cable between the Raspberry Pi 5 and the HMI 8CS display.
- Resolution: Confirm you are using a micro-HDMI to HDMI cable or adapter. The Raspberry Pi 5 has micro-HDMI outputs; the HMI 8CS has a standard full-size HDMI input. A standard HDMI-to-HDMI cable will not fit the Pi's port. Try reseating the cable at both ends, then power cycle the system.
