| 63 | h2. Errata |
||
| 64 | |||
| 65 | 40 | Maximilian Seesslen | * There is only one global 'Enable' line. Not a big deal, the power supplies can be switched off anyways. None would also work. Usecase is when Controller board has same power supply as Driver boards, it can disable drivers when it only wants to feed VBUS. |
