Raspberry Pi Zero PWM Audio Board

Allows PWN audio to be taken from the Pi's GPIO header (on a choice of two sets of pins), and output to powered speakers. The audio circuit is available to download from Raspberry Pi.org. R1/R3 = 270R R2/R4 = 150R C1/C3 = 33nF C2/C4 = 10uF D1 & D2 are optional static protection PCBWay were fast and produced good quality PCBs, thanks very much!
