FeaturesINA219-40 c to + 85 c temperature range and can realize the maximum error of 1% accuracy, maximum offset of 100 uV.The advantage of the high precision of the product in combination with 12 resolution, can help clients as much as possible, reduce the pressure drop on the shunt resistor, which can minimize the power loss and power consumption, and saving board space. The device epic of 26 bus voltage range of 0 V to + V.INA219 other important features include:Calibration programmable registers can directly read its unit of measure is the ampere current, and power in watts per read. For as many as 128 sampling averaging, in order to realize filter in 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 support software programmable INA219. Using single power supply, the working voltage between + 3.0 to + 5.5 V.Package Included:1 x CJMCU-219 moduleNote:Due to the difference between different monitors, the picture may not reflect the actual color of the item. Thank you! Manual measurement, please allow 1-10mm error. Thanks for your understanding.
