This board is a simple carrier of Broadcom’s bidirectional ±20A ACHS-7122 Hall effect-based linear current sensor, which offers a low-resistance (~0.7 m?) current path and electrical isolation up to 3 kV RMS. This version accepts a bidirectional current input with a magnitude up to 20 A and outputs a proportional analog voltage (100 mV/A) centered at 2.5 V with a typical error of ±1.5%. It operates from 4.5 V to 5.5 V and is intended for use in 5 V systems.

Key Features

  • Live measurement – Reads current or voltage while the circuit runs
  • Microcontroller output – Signal ready for ADC or digital interfaces
  • Monitoring – Useful for power and battery projects
