Completed first build of revision A. The new PCB fabrication company turns out okay so far. Comes from the U.S., less money and faster delivery. I still have to debug the hardware and look for flaws. Initial tests show functionality, but there are component values that probably need attention. Plus the need for a jump or two.
The blue trim control is for duty cycle variable control and the momentary switch-button sends a one-shot pulse to the output header. The second pass will be with an Arduino SBC to control its output clock speed.
