** NOTE ** On the Mightyboard Rev E schematic, the SD card section is labeled as SD & MMC card, but the pinout as drawn is for the microSD card (cf. http://elm-chan.org/docs/mmc/m... vs http://elm-chan.org/docs/mmc/s... -- a quick check of fab drawing confirms that it was supposed to be a Micro SD card slot.
Whan I press check button in Eage it shows errors in all +3.3V connections "output and supply pins mixed on net 3.3V".
I try to modify board such as it in real. I want to connect mic2920 input with +5V etc. In this schemaics mic2920 conect to +24V. I can't modify the board with this error messages. Can anyone help?
