i have not yet chosen the shunt resistor for current sensing, or the gain for the INA216

I used the INA219 a while back, and learnt about the different types of mounting for shunt resistors. Went for a 6 pad design after reading the analog devices app note.

Yeah I might switch to a 4-terminal layout but the part that throws me off vs e.g. the INA226 is that it actually draws power from the high side of the shunt
