## Description

The Adafruit INA219 FeatherWing is a high-side current and voltage sensor that stacks onto any Feather development board. Using the INA219B chip over I2C, it measures both DC current draw and bus voltage with 1% precision — replacing the need for two separate multimeters in your power-monitoring setup. Unlike low-side current sensors that disrupt ground references, the INA219 measures on the high side and handles up to +26V DC, even when powered from the Feather's 3.3V rail. It's ideal for monitoring battery life, solar panel output, or any DC power system. Key Features High-Side Current Sensing – Measures current without disrupting ground references, up to +26V DC ±3.2A Measurement Range – 0.1Ω 1% sense resistor with 0.8 mA resolution at full range ±400 mA Low-Range Mode – Internal gain set to ÷8 for 0.1 mA resolution Voltage Monitoring – Reports high-side bus voltage for battery and solar tracking I2C Interface – Simple two-wire connection; configurable address supports up to 4 Wings per Feather 12-bit ADC – Onboard analogue-to-digital converter for precise measurements Feather Form Factor – Stacks directly onto any Feather board Customisable Range – Replace the 0.1Ω sense resistor with your own (e.g., 0.01Ω for up to ±32A at 8 mA resolution) Ideal For Battery life monitoring and power profiling Solar panel current and voltage tracking Embedded system power consumption analysis Any Feather project requiring precision DC power measurement Package Contents 1× Adafruit INA219 FeatherWing Resources Adafruit INA219 Current Sensor Guide
