Boardoza INA260 Digital Current and Power Monitor Breakout Board
The INA260 is a digital-output, current, power, and voltage monitor with an I2C and SMBus™-compatible interface with an integrated precision shunt resistor. It enables high-accuracy current and power measurements and over-current detection at common-mode voltages that can vary from 0 V to 36V, independent of the supply voltage. The device is a bidirectional, low- or high-side, current-shunt monitor that measures current flowing through the internal current-sensing resistor. The integration of the precision current-sensing resistor provides calibration-equivalent measurement accuracy with
ultra-low temperature drift performance and ensures that an optimized Kelvin layout for the sensing resistor is always obtained. By default, pins A0 and A1 (Address pin) are connected to ground, but if you solder JP1(A0) and JP2(A1), you will connect pins A0 and A1 to VCC.
With the load powered off, connect the IN+ and IN– terminals in series with the load, as shown in Figure 2-3. Make sure the current does not exceed 15A. If desired, the current can be split across the two terminals for IN+ or IN–. Alternatively, the additional input pins can be used to connect to the VBUS terminal.
