DC Current Sensor -10A to +10A Logic 3.3V

This board is a simple carrier of Allegro’s ACS71240KEXBLT-010B3 Hall effect-based linear current sensor, which offers a low-resistance (~0.6 mΩ) current path and a high 120 kHz bandwidth for fast response times. This version accepts a bidirectional current input with a magnitude up to 10 A. It operates from 3.0V to 3.6V and is intended for use in 3.3V systems.
