Massive update from Rev C design in terms of optimizations. Most changes include simplification of the power supply and DNPing various parts. Another huge update was pulling back the ground pours near the RF traces and making better via fences. No Rev C boards were ever built. Instead we opted to go immediately to Rev D1.
Rev D1 is a Rev D Faraday optimized for PCB:NG manufacturing. Largely this involves PCB stack-up for 50 Ohm impedance traces. We will not be controlling impedance during manufacturing but it's best to get close! Likely good enough per our current testing.
