| 10 | |
| 11 | The Lynxmotion LSS 5VR ("Lynxmotion Smart Servo to 5 Volt Regulator") module provides a regulated output of 5V at up to 2A from a 6.5V to 12.6V input via the LSS Bus. The board was conceived to be similar to a "Battery Elimination Circuit", or "BEC", as well as being used to power external 5V devices such as RC servos, sensors and/or USB powered devices. The LSS-5VR can be used with an LSS-2IO to power and control RC servos. |

| 13 | Note that the board does not include any circuitry for detecting or charging devices via USB, and does not meet USB 2.0 / 3.0 or other power switch requirements or standards. |
