CJMCU-219 is a module with the I2C interface of zero drift and bi-directional current/power monitoring and control ic. It can solve many power-monitoring problems. The device adopts the SOT23 packaging, but for the server, notebook computer, power supply, battery management, and digital electric vehicle and telecommunication equipment measuring flu provide a small low-cost solution.

INA219 other important features include:

• Calibration programmable registers can directly read its unit of measure is the ampere current, and power in watts per reading.
• For as many as 128 samplings averaging, in order to realize filter in the noise environment.
• The I2C interface has a timeout, not only can avoid the bus lock, but also can provide high-speed mode, meet the communication requirements of up to 3.4 MHz.
• All features are supported software programmable INA219.
• Using a single power supply, the working voltage between + 3.0 to + 5.5 V.
