I used this website http://domoticx.com/digitale-fotolijst-merkloos/ to get some reference into accessing the photoframe. Wanted to translate some of it as well as add some of my own notes.
- Uses 5v power
- Has 7 buttons on the right-side of the unit
- Can read USB sticks and SD/MMC/MS Cards
- PC, Mac or Linux
- Cheap FTDI serial adapter, try to get one that can do 3.3V and 5V both
- Guitar picks
- Breakout cables (preferably with Dupont connectors)
You can pop out the backside by using guitar picks. After that I will advice you to unplug the ribbon cable to the display, as well as other wires going into the buttons inputs and power into the screen unit.
First, plug power back into the photo frame, and measure the voltage between VCC and GND. Adjust your serial adapter to 3.3v or 5v accordingly. My measures showed somewhere around 3.3v, so that is the logic level that I'm going to use with the serial adapter.
Disconnect the power to the photo frame at this point.
The UART pins on my board are visible on the right side of the USB port. I connected the serial pins like this:
FTDI Pins | Picture frame pins |
---|---|
GND | GND |
TX | RX |
RX | TX |
- Connect your PC to your serial adapter
- Start a new screen session with the serial adapter, baud rate 115200
- Plug power back into the photo frame

You can browse the filesystem using the "cd" command as usual. However, "ls" doesn't work, use "dir" instead.
You can also type "help" to display all of the commands.

SD Cards and USB memory is mounted like this
Storage type | Drive letter |
---|---|
USB Stick | I: |
SD Card | D: |
You can copy different directories or files into these storage devices by using
cpdir
to copy directories
copy
to copy single files
