The module was defective. Does not measure the correct voltage on both the shunt and the inlet. The values are very low. And on the shunt, no load, generally shows negative voltage. Accordingly, incorrect current indication. Tried to align this software, but the error is not very linear. At 5 v understates the readings by about 3%, at 12 v-by 7%, at a voltage of more than 20-generally gives out some shit.
