I2C Shunt
thingiverse
The first ADS1115 + Voltage Divider measures the voltage. The second measures over a modified INA282 the voltage drop at the shunt. The ADS1115 has a 15-bit resolution plus one for negative values and a maximum sample rate of 860 samples per second each sensor. Wiring diagram follows.
