	The radar board was developed so that a tiny board with the Arduino can be soldered down directly to the Radar Gun. The Arduino project can do anything you want from there. In the demo code below, it simply powers up the gun, triggers the radar gun to start scanning, then just outputs the speed over the USB interface. I also added in pads for a UART connection, so the data can be streamed out there as well. If the radar gun project is of no interest to you, this board makes a pretty slick little breakout for the ATMEGA32U4		The radar board was developed so that a tiny board with the Arduino can be soldered down directly to the Radar Gun.

+Power to the Radar gun is supplied from the 5V USB, stepped down to 3.3V using a Linear Regulator "TC1262-3.3VAB".  The [[Power_Cheater | Power Cheater]] was used for this.  WARNING!!! The gun will pull over 200mA when you pull the trigger, so make sure the supply can handle that load current.
