Product description: Bidirectional current/power sensor - INA219 - 26V 3,2A - STEMMA AT/Qwiic - Adafruit 904

Bidirectionalcurrentandpowersensor manufactured byAdafruit. It has built-inINA219chip, twoSTEMMA QT / Qwiicstandard connectors placed on both sides of the board and leads as solder fields. It is used to measure high DC voltage and current over theI2Cbus with an accuracy of 1%. The sensor can measure maximum voltagefrom 0 V to 26 V DC(despite of 3 V or 5 V power source). The amplifier measures the voltage across a 0.1 Ohm resistor. The maximum input difference of the amplifier is +/- 320 mV, which allows to measure current up to +/- 3.2 A. Witha 12-bit ADC, the measurement resolution is 0.8 A.

Product is compatible with Arduino and Raspberry Pi.

A detaileduser guideis available on the manufacturer's website, which includes wiring diagrams for each controller. The guide makes it significantly easier to get started with the module.
