This project involves designing and implementing a voltage, current, and power meter circuit, leveraging the powerful RP2040 Zero microcontroller, the precision INA219 sensor, and a 3.2-inch ILI9341 SPI 320x240 TFT display. The RP2040 Zero, featuring a dual-core Arm Cortex-M0+ processor running...
Hello
I am working a simple power monitor that uses an Arduino and an INA219 power monitor. The current part is pretty straight forward. However, (understandably) when I leave the the line floating, the bus and shunt voltage readings provide the supply voltage. I wanted to know what are the...
