use dg409 to switch between sensors. (DG409 is 2:4 with 2 address lines, DG408 would be 1:8 with 3 address lines)
2x 5v output.
2x 3v output (switch lamps).
i2c RTC for date (standalone).
CAN for candis.
1xPWM 2xPWM output (trivial canio, workaround fuer lampen. Warum 2?)
1xPWM output buzzer; 17:[[https://www.homofaciens.de/technics-base-circuits-h-bridge_ge.htm]] muesst sein, mit not baustein. canio)
Update via USB is a nice feature. Circuit already available.
SPI-Nand
Most things can be copied from candis.
