Hermeslite
softerhardware/Hermes-Lite2
A second generation low-cost amateur HF software defined radio transceiver.
Boards in 60 GitHub repositories, designed in KiCad, that use the PE4259-63 by pSemi (-40℃~+85℃ 0.35dB 1.8V~3.3V 10MHz~3GHz 30dB 33.5dBm Integrated control logic SPDT SC-70-6 RF Switches ROHS). See how each wires it, with its parts, size, README and files; the PE4259-63’s symbol, footprint and pinout are on its own page.
