5 of 5 2004 (20x4) Character LCD with I2C backpack April 2, 2019
By: Don Hall from MA United States  
Finally got to my "Furnace Enhancement" box.  Used 3 of these with an Arduino Uno to display the (6) loop temperatures on my furnace. (Along with the temp. probes) for a very low cost, yet very accurate tool for monitoring the heating system.

Really great product!  Is there a Mechanical Drawing to get exact dimensions on the mounting holes?
