The INA228 Breakout Board from PMD Way is an all-in-one current, voltage, and power sensing solution designed for ultimate flexibility and precision. Capable of handling up to 85VDC on either the high or low side, this board features a massive 20-bit ADC to accurately measure everything from microamps to amps. Thanks to its standard I2C interface, configuring alerts, oversampling, and gain settings is entirely effortless. Key Capabilities & SpecificationsVersatile Measurement: Monitors high- or low-side DC current and bus voltage, automatically calculating total power with better than 1% accuracy. Dual-Range Precision: Featuring an onboard 15mΩ (0.1%) shunt resistor, it supports two measurement modes: High-Current Mode: Up to 10A continuous with a 10µA resolution. Low-Current Mode: Up to 2.75A continuous with a 2.5µA resolution. Broad Compatibility: Operates on both 3V and 5V logic. It integrates seamlessly with Arduino, Circuit/microPython-compatible microcontrollers, and single-board computers like the Raspberry Pi. Uses an I2C interface, and the board has the popular I2C bus connectors found on various distributors systems Note: Designed exclusively for DC circuits; not compatible with AC voltages. Overcoming Traditional LimitationsStandard current sensors often force a compromise. Low-side sensors can disrupt your ground reference, while alternative high-side sensors (like the INA219B) usually require swapping physical shunt resistors to change ranges. The INA228 eliminates these hurdles entirely, offering dynamic range and multi-side measurement on a single chip. Wiring ConfigurationLow-Side Sensing: Connect VIN- to ground and VIN+ to the lowest potential of your load. VBUS should tie to your main project voltage (up to 85V). High-Side Sensing (Standard): Connect both VIN+ and VBUS to your main project voltage, and VIN- to the highest potential of your load. You can easily bridge the onboard rear jumper to simplify this connection. What’s Included: A fully assembled breakout board, a 3.5mm terminal block, and standard header pins (requires basic soldering for breadboard use). Use the options menu to select between individual units, or save money with packs of five or ten. All include free delivery.
