KR Sense Current and Voltage Sensor - 45A SF_Weather Another nice element to thisThe KR Sense 45A is a small voltage and current sense breakout board. DC current is determined by measuring a voltage drop across a parallel shunt resistor, then converted to a final analog voltage output by the INA 169. Voltage sense is accomplished by scaling to 3. 3V ADC range by a precision resistor divider. This version of the sensor features a maximum voltage tolerance of 51. 8V at 44. 7A, to be exact. Please be aware that KR Sense boards are
