Ina219 shunt resistor value

Witryna20 lut 2024 · I am using STM32 nucleo-F446RE to interface the INA219 (breakout board). The shunt resistor value is 100mOhm (integrated in the breakout board). In my test, I am trying to read a small load just to learn how to do it. I expect to read about 20mA, with 5V bus voltage.
