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, "25Q806CP". (see jal2's link for likely datasheet of 2.5v 8MBit spi mem and discussion of Hi1018D).
Notice that on the bottom of the PCB in the picture above that there are two pads for serial (labeled RX, TX)
I guess the chip in picture 3 is labeled "25Q80..." which could be a W25Q80xx, i.e. a SPI flash (8MBit) from Winbond, e.g. this one Any idea what the chinese instructions on the PCB bottom mean? Some Info about the HI1018. (jal2)
