Clone of Based on the YuSynth Quadrature VC-LFO. Eagle design, 0805 chip parts with through hole jacks, pot and LEDs. Range runs from 19 Hz down to one cycle in twenty minutes, at plus or minus 5V, and it takes about seven seconds to stabilise after power up. The board is 100 by 45.2mm; the panel width is not stated, so HP is left blank. The BOM link in the README points at charon.sk, which now returns 404.
