Hi friends,
I´m starting during my holiday with building the N8-2312 version.
Are there all actual documents (schematic, PCB, BOM) on the WikI?
Regards
Wolfgang

Hi Max,
I'm almost certain that the 2312 variant of the board
corrected all of that. Those issues were on the 2511. Also,
the 2312 supports CSIO with no board mods.
Thanks!

Hi
Douglas,
From memory, there is a trace cut you need to make on that
board. As it is the trace pulls one of the SD card lines up
to 5V. Also, I'm not sure which driver you are using but, the
board is setup to use spare bits in the RTC IO address rather
than the CSIO port of the Z180 for the SD card. Probably a
couple of additional trace cuts required there as well.
Regards,
Max
