Arduino has bought out second revisions of its Nano 33 BLE and Nano 33 BLE Sense bluetooth-equipped microcontroller boards, keeping the sensor mix, but changing several of the sensor ICs.

The Arduino Nano 33 BLE Rev2 is a significant leap forward in the world of microcontroller boards, designed to empower a diverse array of projects with its advanced capabilities.

These measurements require a completely non-invasive technique, and to satisfy that demand there are commercial magnetometer current probes.
