First of all, note that the circuit as it stands is only really intended to show how a basic current sensor module can be built and act as a stimulus for further improvement. The design is centered ...

Stand-alone coreless, differential current sensing is ... while the sensor’s 4× higher sensitivity range enables flexible busbar and PCB designs.

His blog post does not have the board layout, but the pictures of the PCB should be enough for someone wanting to build their own version of this current sensor.

Integrating a shunt resistor and Hall-based current sensor into a single device helps simplify EV architectures and enhances ...
