Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Is it possible to attach a keyboard to this board? It seems that the required keyboard connection to GP8 and GP9 is not available.  Is it possible to use the keyboard on any other pins?

This board is incompatible with PS2 keyboard use. For console use SPI displays are too slow so the KBD pins were chosen to be compatible with the SSD1963 displays. You can of course use the KBD with displays where you have more flexibility in connection like the ILI9481 and ILI9341
