For those interested, I have support documents, bom, PCB fab files cleaned up and ready to go. I hear the wiki is down, so for now you’ll need to pm me so I can email them to you. I made some final changes to the code, most notably motor amp display up to 9,999, optional temperature compensation of traction battery capacity and leading zero suppression (creates better visual for amp magnitude changes).
Excluding the bare PCB & shipping costs, the material costs for LCD display and all components will be in the $43~50 range. More towards $43 if you want to forgo canbus. I have no code written to support it at this point anyway.
Keep in mind that this is designed around the very common Hitachi 44780 LCD controller. With minor code changes, this would support up to a 40char x 2 line LCD. Steal an I/O line (possible if you eliminate CAN) and you can expand this to a 40char x 4 line LCD.
