A modernized controller PCB for the Brand New Model F and Beam Spring keyboards
The LMV339D is a comparator made by onsemi in a SOIC-14 package with 14 pins. -40℃~+85℃ 1.7mV 1nA 200ns 60uA Four channels SOIC-14 Comparators ROHS.
PCBKit's library has its KiCad symbol (Comparator:LMV339, from KiCad's library) and its footprint (Package_SO:SOIC-14_3.9x8.7mm_P1.27mm, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C463767). 3 open-source boards in 2 repositories on GitHub use it.
