Gobox audio
mfhepp/gobox-audio
A small PCB with a LM386-based audio amplifier for a control monitor, and a zero-beat indicator for QRP rigs, like the Mountain Topper MTR-3B and MTR-5B.

The LMC567CM is a telecom Interface IC made by Texas Instruments in a SOIC-8 package with 8 pins. -25℃~+100℃ 2V~9V SOIC-8 Telecom Interface ICs ROHS.
PCBKit's library has its KiCad symbol (EasyEDA_Cloud:LM567CN, from EasyEDA) and its footprint (Package_SO:SOIC-8_3.9x4.9mm_P1.27mm, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C3678955). 1 open-source board in 1 repository on GitHub use it.
