SparkFun Current Sensor Breakout - INA169 SF_Educators Digital I/O Mode

Digital I/O Mode

The SparkFun Qwiic High Precision Temperature breakout is a high precision temperature sensor equipped with an I2C interface

The other wires are loose

the low-level peripherals on the Pi make it great for hardware hacking

SparkFun Current Sensor Breakout - INA169 SF_Educators Digital I/O ModeThe INA169 is a high side current monitor, which means that you place a resistor (a shunt resistor) on the positive power rail and the INA169 measures the voltage drop across that resistor. The INA169 outputs a small current based on the measured voltage drop. If you place a resistor from the output of the INA169 to ground, you can measure the voltage at the output. Input common mode and power supply voltages are independent and can range from 2. 7V
