BOMs: digikey detailed / digikey aggregated
This board consists of:
12 channel analog input - LMV324ID
12 channel low side - VNS14NV04 (injectors & solenoids)
6 channel hi side (ignition modules) - TC4427
VR input - MAX9926
CAN bus- SN65HVD230
microSD & USB TTL - FT232RL
So this 10x10cm board would be sitting above or underneath the discovery board like this
I guess it's better to have the board underneath the discovery so that I can still have access to the reset button & the LEDs. On the other hand I need access to the components on the Frankenstein board so soldering the boards together is probably not an option.
