Usecases:
4
* sensor for 4 sensors
5
6 1 Redmine Admin
use dg409 to switch between sensors. (DG409 is 2:4 with 2 address lines, DG408 would be 1:8 with 3 address lines)
7 6 Redmine Admin
Dann kann ground gleich mit geschaltet werden und mehrere sensoren sllten sich nicht beeinflussen.

* 2x 5v output for pumps.
9
* i2c RTC for date (standalone).
10
* CAN for candis.
11 1 Redmine Admin
1xPWM output (trivial canio, workaround fuer lampen. Warum 2?)
12
1xPWM output buzzer; 17:[[https://www.homofaciens.de/technics-base-circuits-h-bridge_ge.htm]] muesst sein, mit not baustein.
13
      Wenn invertiertes PWM-Signal vorhanden ist, spart man sich nen enable. NOT + NAND

* Update via USB is a nice feature. Circuit already available.
15
* RTC for switching lamps, standalone 
16
* PWM output for lamps
17
* loud buzzer for alarm/alarm-clock
18
* button for confirm stuff
19
* OUT output for lamps; 2x3V (plant lamp/room lamp)
20
* 2LEDs regular
21 1 Redmine Admin
* SPI NAND-Flash
22 6 Redmine Admin
* Switch connection VUSB to can
