# Description

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.

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.

# Features

- Type A USB female connector (5V power output, no data)
- 2x LSS connectors allow for daisy chaining
- 2x three row pins (NC / 5V / GND)
- Buck converter (up to 95% efficient)
- Vin (6.5V - 12.6V) LED
- 5V output status LED
- Lynxmotion Smart Servo (LSS) mounting pattern
- Same form factor as the LSS - Power Hub and similar modules.

# Specifications

- Based on the TS30042 buck converter
- 5V output (5.3V unloaded)
- Maximum output current: 2 Amps continuous / total
