It is a 40€ picture frame from a local mediamarkt. The PCB appears to be 2 layer with lots of helpful labeling. The microcontroller is a Haier "Hi1018D". Also there is a chip whose marking, "25Q06CP", i cannot find any details for. I will fill this in with details as I find them.
Notice that on the bottom there are two pads for serial (labeled RX, TX)
