No trim pot on the LCD contrast pin, so depending on conditions, the LCD is almost impossible to read. A really silly way to save a few pennies to then charge 48 bucks anyways. Removing R5 from the bottom, and just shorting the pads together seemed to help a little, but for how much the seller charges for this module, this should not be a thing.
