The connector is a little different from the picture, the pin order is the same.
| Pin Number |
Pin Name |
Description (may be empty) |
| 1 | 6,8vdc | 0,625Ah (only for charging, I think) |
| 2 | 12vdc (?!) | Not present in the power supply label (maybe not necessary). |
| 3 | 5vdc | 2Ah |
| 4 | GND | The metal ring around the pins is connected with GND, same as pin 4. |
The power supply label indicates +5v and +6,8v, but I could measure even a +12v in pin 2.
