Power Monitor (INA219)

Monitor voltage, current, and power consumption in real time with this INA219-based sensor module. Measure up to 26V and 3.2A on the high side without disrupting your circuit, perfect for battery monitoring, solar projects, or tracking power draw in embedded systems. The onboard INA219 handles the math internally, delivering voltage, current, and power readings over I²C so your microcontroller doesn't have to crunch numbers. Screw terminals make it easy to insert into your power path, while STEMMA QT connectors let you daisy-chain I²C devices. Drop it into any backplane and start tracking power consumption with Arduino IDE, MicroPython, or MicroBlocks. Use it standalone with any microcontroller, or snap it into the Genesis Modular system from Axiometa for plug-and-play integration. Works with Arduino IDE, MicroPython, or MicroBlocks.
