C25,C26,C27,C28 can be replaced with
0603 tantalum caps eG: mouser ID: 581-TACL474K010X
for best RX performance.
Watch for Polarity in that case -> Minus to GND !
Changelog:
Rev. 1.0: Initial Release
Rev. 1.1: Separated "clean" 5V Line from "dirty" VCC line. (Never released)
Rev. 1.2: Inserted caps on OpAmp Inputs to compensate OPAmp DC Offsets,
+Added Reverse Polarity protection (Diode + Polyfuse)
