| 28 | 8 | Maximilian Seesslen | * Switch 4 power lines |
| 29 | 13 | Maximilian Seesslen | ** [VBus, Plant lamp, Media, illumination] or [VBus, Plant lamp, 2 x Illumination]; VBus can be on of the illumination supplies |
| 30 | 8 | Maximilian Seesslen | * Can start via RTC or Button |
| 31 | 9 | Maximilian Seesslen | * Measure power consumption |
| 32 | * 4 PWM signals for regulator board(s) |
||
| 33 | 1 | Maximilian Seesslen | * External I2C bus for regulator board(s) |
| 34 | * USB port for configuration |
||
| 35 | * 3 CAN connectors to have it somwhere in the middle of the bus + Display or to have 5V+12V bus |

| 66 | 30 | Maximilian Seesslen | |
| 67 | h2. Errata |
||
| 68 | |||
| 69 | 44 | Maximilian Seesslen | * There is only one global 'Enable' signal to the driver boards. Not a big deal, the power supplies can be switched off anyways. |
| 70 | ** Usecase: When Controller board shares power supply with Driver boards, it can disable drivers when it only wants to feed VBUS. |
