ED-HMI3020 Pi 5 touchscreen review

By Phil King. Posted

Designed for industrial settings, the EDI-HMI3020 touchscreen panel (From £212 / $268) has a ruggedised housing with a well-protected Raspberry Pi 5 mounted on the rear, cooled passively with a heatsink. It comes in 7-inch (1024×600 pixels) and 10-inch (1200×800) variants with 4GB or 8GB or RAM. We tested out the 8GB, 10-inch model.

While there’s no direct access to Raspberry Pi 5’s GPIO header via the case, the four USB ports are exposed, along with the USB-C power socket, two micro-HDMI ports, microSD card slot, and an Ethernet port with optional PoE functionality.

An upgrade over the HMI3010 models, the HMI3020 adds RS232 and RS485 interfaces, as well as 3.5mm headphone and mic jacks. The key addition, however, is an M.2 socket. To access it, you’ll need to unscrew Raspberry Pi 5 and the case from the rear of the unit, then you can use the M.2 slot inside to add an NVMe 2230, 2242, or 2260 SSD.

Touch control

Our unit’s microSD card had Raspberry Pi OS Bookworm pre-installed with the drivers for the ten-point touchscreen, which worked instantly upon bootup. As we’ve found with other Raspberry Pi touchscreens, there’s no right-click functionality by default and we also couldn’t double-click files to open them (so had to enable one-click opening in the File Manager). There was no on-screen keyboard available either, though we managed to get one running with a workaround from the Raspberry Pi forums.

The EDI-HMI3020 also comes with an optional 8MP front-facing camera – a Camera Module V2 – for video conferencing and suchlike, making it a versatile touchscreen tablet.
