- MISO and MOSI need pull up resistors to 3v3, they are also open-drain outputs
- The 2 pin header for ISO SPI has pins 1 and 2 reversed, they should be swapped.
Revision 2
Retrospective
- Add a FET for switching current sense 12V (reset LTC2484)isoSPI Mode 0 by default (for current sense)
- Add connector for kill switch
- Add ability to switch between master/slave and modes on isoSPI so we can use it as a sniffer
