for next revision let's add external USB connector traces to a USB connector and have vias for all SWD pins so that MRE could be programmed via test fixture

@dron0gus is wondering why do we use TC4427 and IGN TLE8888 outputs @mck1117 reminds us that once upon a time with no supporting data, @960 decided he didn't like them

we want to drill the case for USB cable, we need a rubber plug Should cost under $0.5 each at QTY 10

Low-profile MRE

3

For some PnP applications we want MRE to be very slim. 2x5 headers and even vertical USB connectors are not really required. The tallest required component is 100uF 50V C2...

Re-purpose AV3 analog inputs for 2nd channel hall input (same as existing CAM)

1

at the moment we have one Hall channel and one channel which could be either VR or hall depending on what resistors are mounter. This hardware flexibility is quite labor...

Could we use the empty area above C1 C3 or is that a bad idea for EE reasons? 

U5 - LD1117 is a dollar cheaper

3

LM2937 used for U5 is $1+ while LD1117S33TR from mouser is $20@100. Shall we change U5 to LD1117S33TR? @mck1117 believes the pinout is different so schematics and PCB would need...

reverse voltage protection of TLE9201 and etc

1

DonaldBecker says "The v0.3 MRE appears to have a weakness with reverse voltage protection (when the battery is connected in reverse, applying -12V to the +12V circuit). Specifically unprotected 12V...

Honda, Subaru, vehicle speed sensors are asking for more VR inputs Do we have space and desire for MAX9926? open questions which pins to wire it to on MCU. Open...

in order for logs to have real timestamp we would need 32K crystal and a small 3v battery @960 @mck1117 @jharvey any ideas for a small 3v battery part number?...
