Adafruit INA219 FeatherWing
The INA219 FeatherWing makes power-monitoring problems a thing of the past. Instead of struggling with two multimeters, you can just use the handy INA219 chip on this breakout to measure both the high side voltage and DC current draw over I2C with 1% precision.
Pinout
- VIN
Board power input. Source states to power the board with the same voltage as the microcontroller logic level, for example 5V on Arduino or 3.3V on Feather.
Type · powerVoltage · 2.7V to 5.5V board supply, use same logic level as host - GND
Common ground for board power and logic.
Type · groundVoltage · 0V - SCL
I2C clock line. Source states a 10K pull-up is present on this pin.
Type · i2cVoltage · logic-level I2C, tied to host logic level via board power - SDA
I2C data line. Source states a 10K pull-up is present on this pin.
Type · i2cVoltage · logic-level I2C, tied to host logic level via board power - STEMMA QT
STEMMA QT connector for I2C connection to compatible development boards or accessories.
