MT6701 Hall Based Angle Position Encoder Sensor

Post by parkview » Sun Feb 05, 2023 11:46 am

This is a tiny breakout board for the MT6701 360 degree magnetic rotation field sensor IC. It has a small JST-SH connector for the power and i2C pins. This seems to work really well, and will be used in an up coming project. Unfortunately, it seems the tap function (senses a sudden increase if magnetic field when the magnet is brought closer (tapped) to the sensor doesn't work. The board was hard to photograph, so here it is in place while being tested via a ESP32 Dev board:

For this to work, you need a special 6mm Diametrically Neodymium Magnet - not the usual magnet where each pole is North or South:
