The INA226 is a current shunt and power monitor with an I2C or SMBUS-compatible interface. ALERT: Digital output/multifunction alert. Open-drain output. SCL: Digital input/serial bus clock line, open-drain input.
This product utilizes the I2C interface to achieve 16 I/O port expansion. It is compatible with models such as Raspberry Pi Zero/Zero W/Zero WH/2B/3B/3B+/4B, as well as Arduino and STM32. We provide C and Python versions of the program for Raspberry Pi, as well as Arduino and STM32 versions, which enable input testing, output testing, and interrupt testing.
