 The USER button connects to GPIO36 on the RP2350 which allows it to be programmed for various purposes. The RESET button does just what its name suggests and resets the entire board when pressed. This can help to reboot the robot or to restart a sequence you want the Robotics Kit to perform. Holding the BOOT button either when plugging in a USB cable or when pressing the RESET button sets the RP2350 to behave as a mass storage device when connected to a computer for uploading firmware.

-These LEDs are there to provide a visual indication to users. The LEDs labeled <b>MOT</b> and <b>SYS</b> turn on when their respective power rails are powered. The <b>MOT</b> LED turns on when the motors have power available. The <b>SYS</b> LED turns on when the <b>3.3V</b>/System circuit is powered. This circuit powers the RP2350, RM2, sensors, and the expansion connectors. The <b>LOW VOLT</b> LED is a quick visual indicator to notify users that the supply voltage has dropped below the operating threshold and the board is underpowered. This is particularly helpful when powering the XRP Kit with batteries to indicate they need to be recharged or swapped.

 The other two LEDs labeled <b>STAT</b> and <b>RGB</b> are user-programmable status LEDs you can program for whatever behavior you prefer. The <b>STAT</b> LED connects to GPIO0 on the Radio Module and can be useful to indicate behavior from the radio such as connection status or data transmission. The <b>RGB</b> LED connects to GPIO37 on the RP2350 and can be programmed to change to any color based on whatever behavior you'd like. For example, you can have it turn from Green to Red when the distance sensor detects the robot is nearing an obstacle.

 Welcome to the SparkFun Experiential Robotics Platform (XRP) Controller Hardware Overview. This document provides detailed overviews of the hardware present on both versions of the XRP Controller; the [XRP Controller](https://www.sparkfun.com/sparkfun-experiential-robotics-platform-xrp-controller.html) and [XRP Controller - Beta](https://www.sparkfun.com/sparkfun-experiential-robotics-platform-xrp-controller-beta.html).
 
 Each version of the XRP Controller has their own hardware overview section linked in the navigation menu to the left. If you're not sure which version to select, click on the image below matching the XRP Controller you have:
