Boardoza TMCS1101A2B Bidirectional Current Sensor Breakout Board

The TMCS1101A2B-based current sensing board is a high-performance and wide-range monitoring solution for industrial and power electronics applications. At the heart of the board is the TMCS1101A2BQDR, a Hall-effect current sensor with 100 mV/A sensitivity and galvanic isolation, offering both safety and precision.

Unlike low-current variants, this version features a zero-current output of 0.5 × Vcc, enabling bidirectional current measurement up to ±23A (at 5V) with excellent linearity and noise immunity. This makes it ideal for motor drivers, power management systems, battery monitors, and other medium to high current applications.

Depending on your system configuration, the analog output can be read directly or processed through I2C-connected ADCs, thanks to onboard conversion options. The board supports analog and digital modes, switchable for maximum integration flexibility.

With its power indicator LED and compact form factor, this module combines accuracy, safety, and versatility — all in one.
