Description What does "P" mean? "P" is for "panel mount" in this product. This Grove - Rotary Angle Sensor is a sister version of original Grove - Rotary Angle Sensor. They are identical except the Grove connecter is moved to the back so that you can easily use it as a neat and wire-free human interface device. For all Grove users (especially beginners), we provide you guidance PDF documents. Please download and read through Preface - Getting Started and Introduction to Grove before your using of the product. https://elecena.pl/product/9696479/101020048-arduino-grove-rotary-angle-sensor-p 2017-08-05 https://elecena.pl/product/9696479/101020048-arduino-grove-rotary-angle-sensor-p 2017-10-18 https://elecena.pl/product/9696479/101020048-arduino-grove-rotary-angle-sensor-p 2018-01-25 https://elecena.pl/product/9696479/101020048-arduino-grove-rotary-angle-sensor-p 2021-11-04 https://elecena.pl/product/9696479/101020048-arduino-grove-rotary-angle-sensor-p 2023-04-04 https://elecena.pl/product/9696479/101020048-arduino-grove-rotary-angle-sensor-p 2023-08-20 https://elecena.pl/product/9696479/101020048-arduino-grove-rotary-angle-sensor-p 2025-09-04 https://elecena.pl/product/9696479/101020048-arduino-grove-rotary-angle-sensor-p 2026-02-20
