Boards in 1 GitHub repository, designed in KiCad, that use the ADE-2ASK+ by Mini-Circuits (-40℃~+85℃ 0MHz~1GHz 1 1MHz~1GHz 1MHz~1GHz 1dBm 5.4dB、6.8dB、7.83dB 50dBm 64.1dB 67.9dB SMD-6P,7.9x5.6mm RF Mixers ROHS). See how each wires it, with its parts, size, README and files; the ADE-2ASK+’s symbol, footprint and pinout are on its own page.
