All about the product
Bidirectional current and power sensor made by Adafruit. It has an INA219 chip built in, two STEMMA QT / Qwiic standard connectors located on both sides of the board, and wires as solder pads. Used to measure high DC voltage and current over the I2C bus with 1% accuracy. The sensor can measure a maximum voltage from 0 V to 26 V DC (regardless of 3 V or 5 V power supply). The amplifier measures the voltage across a 0.1 Ohm resistor. The maximum input difference of the amplifier is +/-320 mV, which allows you to measure current up to +/-3.2 A. Using a 12-bit ADC, the measurement resolution is 0.8 A.Specifications:
