| 3 | 5 | Redmine Admin | 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 | 5 | Redmine Admin | * 2x 5v output for pumps. |
| 8 | * i2c RTC for date (standalone). |
||
| 9 | * CAN for candis. |
||
| 10 | 1 | Redmine Admin | 1xPWM output (trivial canio, workaround fuer lampen. Warum 2?) |
| 11 | 1xPWM output buzzer; 17:[[https://www.homofaciens.de/technics-base-circuits-h-bridge_ge.htm]] muesst sein, mit not baustein. |
||
| 12 | Wenn invertiertes PWM-Signal vorhanden ist, spart man sich nen enable. NOT + NAND |
||
| 13 | 5 | Redmine Admin | * Update via USB is a nice feature. Circuit already available. |
| 14 | * RTC for switching lamps, standalone |
||
| 15 | * PWM output for lamps |
||
| 16 | * loud buzzer for alarm/alarm-clock |
||
| 17 | * button for confirm stuff |
||
| 18 | * OUT output for lamps; 2x3V (plant lamp/room lamp) |
||
| 19 | * 2LEDs regular |
||
| 20 | * SPI NAND-Flash |
||
| 21 | * VUSB to can? Switch? |

| 24 | Most things can be copied from candis. |
