{"product_id":"ina228-20-bit-current-voltage-supervisor","title":"INA228 20-Bit Current\/Voltage Supervisor","description":"\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eKey Capabilities \u0026amp; Specifications\u003c\/em\u003e\u003cbr\u003eVersatile Measurement: Monitors high- or low-side DC current and bus voltage, automatically calculating total power with better than 1% accuracy.\u003c\/p\u003e\n\u003cp\u003eDual-Range Precision: Featuring an onboard 15mΩ (0.1%) shunt resistor, it supports two measurement modes:\u003c\/p\u003e\n\u003cp\u003eHigh-Current Mode: Up to 10A continuous with a 10µA resolution.\u003c\/p\u003e\n\u003cp\u003eLow-Current Mode: Up to 2.75A continuous with a 2.5µA resolution.\u003c\/p\u003e\n\u003cp\u003eBroad 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.\u003c\/p\u003e\n\u003cp\u003eUses an I2C interface, and the board has the popular I2C bus connectors found on various distributors systems\u003c\/p\u003e\n\u003cp\u003eNote: Designed exclusively for DC circuits; not compatible with AC voltages.\u003c\/p\u003e\n\u003cp\u003eOvercoming Traditional Limitations\u003cbr\u003eStandard 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.\u003c\/p\u003e\n\u003cp\u003eWiring Configuration\u003cbr\u003eLow-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).\u003c\/p\u003e\n\u003cp\u003eHigh-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.\u003c\/p\u003e\n\u003cp\u003eWhat’s Included: A fully assembled breakout board, a 3.5mm terminal block, and standard header pins (requires basic soldering for breadboard use).\u003c\/p\u003e\n\u003cp\u003eUse the options menu to select between individual units, or save money with packs of five or ten.
