The INA219 High Side DC Voltage Sensor Breakout from Adafruit is a highly advanced electronics module specifically designed for precise power monitoring. With the integrated INA219B chip, this breakout board allows for the measurement of high-side voltages and DC current readings via I2C with an accuracy of 1%. Unlike traditional current meters that are often only suitable for low voltage measurements, this module can measure voltages up to +26 VDC while operating on a supply voltage of just 3 or 5 V. This makes it ideal for applications where monitoring battery life or solar panels is necessary. The integrated precision amplifier measures voltage across a 0.1 Ohm, 1% sense resistor and allows for current measurements up to ±3.2 Amperes. With an internal 12-bit ADC, the module provides high resolution for accurate measurements.

• High-side current measurement up to +26 VDC
