The “propeller one”:
It has a serial port, TV out, keyboard connector,
SD card connector and expansion ports.
You can use the Parallax demo programms with it.
I just loaded the graphics demo on it and it worked…
The board has two expansion ports one with 13 pins and
a smaller one with 4 pins for future expansions.
The SD card module is on the top (with a blue SD card plugged in).
It was sold by tdus shop.
