The Glorious BAMF sensor has a very wide CPI range that you can adjust in small increments. It undershoots a bit, but it shouldn’t be a problem for most people. The lift-off distance is advertised to be as low as 0.7 mm, but we can only test in increments of 1.2 mm. Lastly, you can adjust its polling rate from 125Hz, 250Hz, 500Hz, or 1000Hz.
