The current detection solution used to replace ina226 has been board verified and can be directly used in pixhawk flight control (current to voltage ratio 33.3)
The amplifier uses GS5881, the sampling resistor is 0.3mR, and the amplification is 100 times.
The calculation is as follows:
100K/1K=100
0.3mR*100A*100=3V
After calibration on the pixhawk flight controller, the test is as shown below
