From the project
How to use: the BOM excel includes all the things you need.
How to use: the BOM excel includes all the things you need.
The release file is the file you need to hand in to the PCB manufaturer.
Like JLCPCB,Foxconn,SCC,TTM Technologies.
VCO module can be replaced to anyother VCO module to block any frequence!
This is the first project I released in Github
Anyway of usage is allowed,including editing、modifying、fixing
