Would it run fine on a raspberry pi3b (not 3b+) ?
Thanks !
The loop should work fine. There is a 75 ohm bnc male connector on the mylaps cable. You need a bnc-to-sma adapter to connect it to an sdr. The 75-50 ohm bnc connectors mate fine without damage.
I did not test with rpi3b. The decoding process requires both usb i/o and cpu, and b+ improved on both over model 3b. On a b3+, the cpu usage is about 40% of a single core, so I'd expect a 3b to work just as well. Note though, you can use the same host computer which runs the lap counting software. On my 1.7 ghz intel cpu from 2013, the cpu usage is less than 3%.
