INA219 I2C bidirectional DC power sensor
Parameters:
Size: 25.5*22.3mm
Operating voltage: 3-5V
Bus voltage range: 0 - +26V
Temperature range: -40°C to +85°C
Error accuracy: 1% (maximum offset voltage: 100 uV)
Features:
1. Programmable calibration registers can directly read current in amperes and read power in watts
2. Up to 128 samples can be averaged to achieve filtering in a noisy environment
3. The I2C interface has a timeout setting, which not only avoids bus lockup, but also provides a high-speed mode to meet communication requirements up to 3.4 MHz
4. All features of INA219 support software programmability
5. Powered by a single power supply, its operating voltage is between +3.0 and +5.5V
