#75798 As mentioned previously these boards are designed for LDO regulators which have a different pin out to the 117 type. So the article is moaning about an incorrect pin out but they have assumed a regulator that the board is not designed for.

The 117 are not really LDO and also have a high quiescent current so not a great choice particularly for applications using batteries.
