New current sensor breakout boards

This video introduces three new xMR current sensor breakout boards:
a TMR analog bridge sensor with an on-board current strap;
a GMR sensor over-trace current sensor; and
an I²C smart magnetometer over a trace.
All three boards are simple, sensitive, and small. The analog bridge sensors have plenty of signal with no amplification. The I²C sensor is ridiculously simple--just four pins and two lines of microprocessor code. Most microprocessor current sensors are much more complicated. We demonstrate with a Trinket mini microcontroller.
Each of the breakout boards has a business-card sized manual with the pinouts on one side and key sensor specifications on the other. Here are links to the breakout boards we demonstrated:
