KiCAD pcb; whole bunch of RF-related modules, so I can figure out what works and how. I'm a novice, don't trust my boards too hard. Contains: 1x RP2040 with breakout headers 1x Micro-USB connector for 5V, 3V, and programming the RP2040 2x Tayloe Detectors (1x variable gain) 3x Ferrite feedthroughs (various ends) 2x 50Ω Loads 4x Shorts Several inductors, assorted Several capacitors, assorted 2x Headphone jacks 2x Amplifiers (1x variable gain) 1x 50MHz high pass filter 1x 800KHz high pass filter 1x 1MHz low pass filter 2x (1-10)MHz band pass filter (two arrangements) 5x LEDs, different colors 2x Laser diodes, different colors 2x Photodiode modules (2x with variable gain, 1x with 16Hz high pass) 2x Microphones 1x Speaker 3x RF mixers (various configurations) 2x De/mux (various configurations) 1x 2.5KHz-200MHz clock 1x DC boost converter (variable) 1x Constant current source (variable) 6x Attenuators (various strengths and topologies, 2x variable) 4x Buttons 8x Junctions 2x Header pin / U.FL adapter sets (4 each) 4x RF switches (two configurations) 2x NFET/PFET pairs ...and anything else I missed. Everything MIT licensed, except a lot of the Tayloe module stuff I got from https://github.com/michalin/easysdr licensed GPL, though most of THAT came from the original Tayloe Detector paper https://www.norcalqrp.org/files/Tayloe_mixer_x3a.pdf, so I dunno how that works exactly. -Erhannis
