The Quad Buffer + Bi-LED PCB is an easy solution to buffering and adding Bi-Color LED indicators to your DIY Serge/Buchla/ Banana based project! The pcb mounts via the traditoinal 4U Serge PCB standards (1” x 3”).
Bill of Materials: (All SMT has been pre-installed for you! )
RLED = Sets LED Brightness (current limiter), recommend starting around 1K-3K3
MTA100 Power header.
AO# = Signal Output (1-4)
AI# = Signal Input (1-4)
LC# = LED Driver Cathode (1-4) If using bi-color, polarity only matters for what color you want positive and negative phases to be
LA# = LED Driver Anode (1-4) If using bi-color, polarity only matters for what color you want positive and negative phases to be
PCB is 1” x3” with 0.132 holes that are inset 0.15” on each corner.
