The CJMCU-219 INA219 I2C Interface No-Drift Bi-Directional Current/Power Supply Monitoring Module includes all you need to hook up.
CJMCU-219 is a module with the I2C interface of zero drift and bi-directional current/power monitoring and control integrated circuit (IC). INA219 has the industry’s highest precision and the smallest size; it can not only monitor the pressure drop on the shunt resistor, sensing shunt power supply voltage, but also calculate the power at the same time.
This breakout board will solve all your power-monitoring problems. Instead of struggling with two multimeters, you can just use the handy INA219 chip on this breakout to measure both the high-side voltage and DC current draw over I2C with 1% precision.
The device adopts the SOT23 packaging, but for the server, notebook computer, power supply, battery management, digital electric vehicle, and telecommunication equipment, measuring flu provides a small, low-cost solution.
A precision amplifier measures the voltage across the 0.1, 1% sense resistor. Since the amplifier’s maximum input difference is ±320 mV, this means it can measure up to ±3.2 amps. With the internal 12-bit ADC, the resolution at the ±3.2A range is 0.8mA. With the internal gain set at the minimum of div8, the max current is ±400 mA and the resolution is 0.1 mA. Advanced hackers can remove the 0.1-ohm current sense resistor and replace it with their own to change the range (say a 0.01-ohm to measure up to 32 Amps with a resolution of mA).
INA219-40 has a -40°C to +85°C temperature range and can realize the maximum error of 1% accuracy and a maximum offset of 100 μV. The advantage of the high precision of the product in combination with 12 resolution can help clients as much as possible and reduce the pressure drop on the shunt resistor, which can minimize the power loss and power consumption and save board space. The device has an epic 26 bus voltage range of 0 V to + V.
INA219's other important features include:
1. Calibration programmable registers can directly read its unit of measure, which is the ampere current, and power in watts per reading.
2. For as many as 128 samplings on average, in order to realize the filter in the noise environment.
3. The I2C interface has a timeout, which not only can avoid the bus lock but also can provide high-speed mode and meet the communication requirements of up to 3.4 MHz.
4. All features are supported by software-programmable INA219.
5. Using a single power supply, the working voltage is between +3.0 and +5.5 V.
