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)
Chinese translate is (thank you Geng): "1. remote_control_head J2 (needs to be?) installed with J9 on same side. 2. remote_control_head feet (needs to be) inserted from the other side of J2 imprint. 3. from the edge of the board, the remote_control_head feet (needs to be) 18mm"
Carsten Meyer made a mod on a very similar frame with the same chipset. No chip details though.
