The Sub-μA Current Sensor is a Kinetis K22F based current measurement board running on FreeRTOS and can be used with the Freedom Development Ecosystem or any other Arduino-like development board.
This reference design allows for non-intrusive connection between any MCU and a 3.3V shield and measurement of a wide range of low currents (~60 nA – 5 mA). Multiple communication methods are available, including integration with Freedom Sensor Toolbox (CE).
