The shield is built around the INA219 chip and includes screw terminals for easy connection of the load, allowing accurate measurement of current, bus voltage, and power.\u003c\/p\u003e\n\u003cp\u003eThe shield can be mounted on the back side of the OLEDUINO-V2, creating a very compact current and power monitoring solution. The INA219 communicates using the I²C protocol, making integration simple and efficient.\u003c\/p\u003e\n\u003cp\u003eThe INA219 is a current shunt and power monitor with an I²C- or SMBus-compatible interface. It measures both the voltage drop across the shunt resistor and the bus supply voltage. The device features programmable conversion times and filtering options for improved measurement accuracy.\u003c\/p\u003e\n\u003cp\u003eA programmable calibration register, combined with an internal multiplier, enables direct current readings in amperes. Additionally, an internal power calculation register provides power readings in watts. The interface supports up to 16 programmable addresses, allowing multiple devices on the same bus.\u003c\/p\u003e\n\u003ch3\u003eArduino Code\u003c\/h3\u003e\n\u003cp\u003eArduino code is provided and intended to test the shield. Upload the code to the OLEDUINO-V2 using the programming connector.
