I bought an A1M8-R5 two years ago and have been very happy with its performance with the Rpi and Nano SBC families. The quality of the R6 model is just as good as that of the R5. I am using R6 with Rpi 4B 4GB with Donkeycar v 4.3 and the collection of distance/angle data is all I could wish for. I highly recommend A1M8-R6 if you can't find money for A2.
