Bidirectional current / power sensor - INA219 - 26V 3,2A - STEMMA AT / Qwiic - Adafruit 904
Bidirectional current and powersensor manufactured by Adafruit. It has an embedded INA219 chip, two STEMMA QT / Qwiic standard connectors located on both sides of the board and leads as solder fields. It is used to measure high DC voltage and current over the I2C bus with an accuracy of 1%. Sensor can measure maximum voltage up to 26 V DC despite of 3 V or 5 V supply.

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.
