Brief overview\n-- F1 is a fuse, you should have an up stream fuse at the source, but in the event you over draw this board, this fuse will blow before traces burn off.\n-- Q2, R3, D2 preform an active transient protection. It will suppress voltages up to 200V, down to 19V.\n-- Q1, R1, D1 preform a reverse polarity protection. If the input signal is the wrong polarity, the gate will not conduct which will prevent current from flowing. \n-- L3 is an RF choke\n-- D3 is a second transient suppressor, it would catch faster transients allowing a brief amount of time for Q2 to preform it's duty. \n-- C1 is a bulk cap, it simply stores energy locally such that the regulator can draw large currents in short periods of time. \n-- U1, D6 L1, C2 are a buck style switching regulator, that will pull the 5V line up to 5V.\n-- R2, D5 is a power indicator, which simply shows you have power\n-- L2, C3  is a low pass filter which prevents RF ripple from getting onto the 5V node.
