The CJMCU-219 is a high-side current and power monitoring sensor module based on the INA219 IC. It offers precision current, voltage, and power measurements over an I2C interface, making it ideal for monitoring battery levels, power supplies, solar panels, or any embedded system needing accurate current readings. With its ability to detect both supply and return current (bi-directional), the module ensures detailed energy diagnostics with minimal drift over time. Its onboard shunt resistor and compact form factor make it a convenient and accurate power monitoring solution for advanced electronic applications.
