| 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 | 6 | Redmine Admin | Dann kann ground gleich mit geschaltet werden und mehrere sensoren sllten sich nicht beeinflussen. |
| 8 | 9 | Redmine Admin | * -2x 5v output for pumps.- Generating 6V somewhere else makes more sense |
| 9 | * i2c RTC for date (standalone), recording |
||
| 10 | 5 | Redmine Admin | * CAN for candis. |
| 11 | 9 | Redmine Admin | * -1xPWM output (trivial canio, workaround fuer lampen. Warum 2?)- anderes projekt |
| 12 | * -1xPWM output buzzer; 17:[[https://www.homofaciens.de/technics-base-circuits-h-bridge_ge.htm]] muesst sein, mit not baustein. |
||
| 13 | 8 | Redmine Admin | Wenn invertiertes PWM-Signal vorhanden ist, spart man sich nen enable. NOT + NAND- anderes Projekt |
| 14 | 9 | Redmine Admin | * -Update via USB is a nice feature. Circuit already available.- Andere MCU |
| 15 | * RTC for -switching lamps- recording |
||
| 16 | * -PWM output for lamps- |
||
| 17 | 8 | Redmine Admin | * -loud buzzer for alarm/alarm-clock- |
| 18 | * -button for confirm stuff- |
||
| 19 | 9 | Redmine Admin | * -OUT output for lamps; 2x3V (plant lamp/room lamp)- |
| 20 | 5 | Redmine Admin | * 2LEDs regular |
| 21 | 1 | Redmine Admin | * SPI NAND-Flash |
| 22 | 9 | Redmine Admin | * -Switch connection VUSB to can- |

| 25 | 1 | Redmine Admin | Most things can be copied from candis. |
