Product description
Breakout board with QWIIC connectors for the versatile voltage and current sensor INA260. This sensor is able to measure current (I), voltage (V) and calculate consumed power (W) with very high accuracy. The sensor can measure both positive and negative current flow using either high- or low-side sensing. The integrated shunt resistor has a tolerance equivalent of 0.1% and an extremely low burden voltage thanks to the 2 mOhm resistance.
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.
