Adapter for Seeed Spectra6 7.3" color epaper panel to fit IKEA RODALM picture frame

The Seeed Spectra6 7.3" panel is one of the most affordable color epaper panels right now. The IKEA RÖDALM 13x18cm frame is a cheap shadowbox frame that not only fits the 7.3" Spectra6 panel, but also has enough room to hold a driver board and battery inside its box.

This adapter makes it easy to mount a Seeed Spectra6 7.3" panel into an IKEA 13x18cm RÖDALM, centering the asymmetric panel vertically. The panel drops into the front, and the cutout at the bottom makes it easy for the ribbon cable to fold back behind the 3D-printed adapter. Using the stock spacer from the frame, you have enough room for a board and battery to fit behind the adapter. Please note: this is for the European version of the RÖDALM - other continents may have different dimensions and would not fit this adapter.

Combine this with a compatible board, like the Seeed EN04 or EE04 for example, and a suitable LiPo battery, and this is one of the cheapest stand-alone color epaper builds you can create right now. I'm using my boards with OpenDisplay firmware, which supports the Seeed boards and epaper panels, and is supported by Home Assistant out of the box.

You can use the stock matte that comes with the IKEA RÖDALM frame, but it's a bit too small so it covers a lot of the Spectra6 panel. Instead, I had a custom matte cut online that matched the exact dimensions of the Spectra6 panel. I used a Dutch webshop but there are similar shops operating in every country.
