It's a mini HDMI decoder board! So small and simple, you can use this board as an all-in-one display driver for TTL displays, or perhaps decoding HDMI/DVI video for some other project. This breakout features the TFP401 for decoding video, and for the touch version, an AR1100 USB resistive touch screen driver. https://elecena.pl/product/17500085/tfp401-hdmi-dvi-decoder-to-40-pin-ttl-breakout-without-touch 2021-04-06 https://elecena.pl/product/17500085/tfp401-hdmi-dvi-decoder-to-40-pin-ttl-breakout-without-touch 2022-04-30
