Product description
High-precision current sensor module with QWIIC connectors. Developed and manufactured by Electrokit. Based on Texas Instruments versatile voltage and current sensor INA260. It can measure current (I), voltage (V), and calculate power consumption (W) with very high accuracy. The sensor can measure both positive and negative current using either high-side or low-side measurement. The integrated shunt resistor has a tolerance of 0.1% and an extremely low voltage drop thanks to its low resistance of 2 mOhm.
The module provides access to all pins from the sensor, including I2C interface, alert output, address pins and a header to configure high- or low-side voltage measurement. I2C access is provided through two JST-SH QWIIC connectors for easy wiring. The current sensing path has wide tracks to minimize PCB resistance and patterns for either a 5.08mm pitch screw terminal, 2.54mm pin header or soldering wires directly to the board.
Two solder jumpers provides access to the two address pins (A0 and A1). Simply short either or both pins to change the I2C address. Up to four devices can be wired to the same I2C bus.
