Flyrobo (4 pc) CJMCU-219 INA219 I2C Interface No Drift Bi-directional Cu - Electronic Components Electronic Hobby Kit

Operating Voltage: 3 ~ 5.5 v DC Operating Temperature Range: -40 to 85 °C Accuracy: ±0.5% 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- 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. Specifications and Features: Reports Current, Voltage, and Power 0.1 ohm 1% 2W current sense resistor Up to +26V target voltage Up to ±3.2A current measurement, with ±0.8mA resolution 0.9″ x 0.8″ PCB PCB (no header or terminal block): 1.9g Calibration Registers Senses Bus Voltages from 0 to 26 V 2C- or SMBus-compatible interface. The 16 Programmable Addresses Filtering Options SOT23-8 and SOIC-8 Packages Package Content: 1 x CJMCU-219 INA219 Module
