The Ploopy Nano 2 has a PAW-3222 sensor with a 1,000 Hz polling rate and a default setting of 1,000 CPI (counts per inch), but support for up to 4,000 CPI.
The nano sensor interface presented below is a microcontroller-based universal sensor interface with a power-saver mechanism. The idea, centered around an Arduino Nano (v3) microcontroller, was ...
