BOM Substitutions

Hey guys, there are some parts from Mouser on backorder but there are substitutions in stock-
TLV2472CP or IP can be used for TLV2472AIP
TRS202EINE4 can be used for TRS202ECN
MHE-132 & MHE-133 can be used for MHE-135 (terminal blocks are tongue & groove and can slide together to make longer lengths)

Other corrections-
Pricing shown for PIC18F2480-I/SP was digi-key. Mouser is cheaper at $5.56
Added 16-pin socket p/n for U7
Changed p/n for 8-pin socket to cheaper one (and now same series as other sockets on this BOM)

I've been working on the code a bit more (is it ever done?) I added 3 more peukert exponents- 1.15,1.10,1.05. The latter intended for LIFEPO4.
I'm also working on some display mode options to help automate what is displayed:
i.e. overtemp condition lights LED and jumps display to temperature screen,
If motor amps=0, SOC screen is displayed. As soon as car starts moving, it jumps to Volts/Amps screen. So anytime you coast or come to an intersection you can see the remaining charge & range without touching anything. Display select button is still funtional though.

apowers, sit tight I didn't want to email you anything until I got the BOM updated.
