  • Further to my previous comment, I've discovered that I had not read the item description properly and therefore tried to run the device off a 5V line instead of 3.3V. Obviously with 3.3V the potentiometer is in fact appropriate. Perhaps then, Sparkfun should consider applying a label over the 5V silk-screen just to make it abundantly clear it is a 3.3V device!

  • I've discovered, to my annoyance, that the potentiometer on the serial backpack is too sensitive (too large a resistance range). The LCD arrived in a 'negative' state (wrong contrast) and adjusting it is like brain surgery with the finest movement required to it set it correctly! Not to mention competing with mechanical hysteresis means this pot needs swapping out for a more appropriate-valued one.

No public wish lists :(
