Polygonus - FOME PNP Brain unit

In scope -

• Critical systems on the majority of PNP targets
• up to 8 cylinder capability built into the brain board
• Full feature set of the protues broken out to pins meaning vheicle board can add the additional circuits if required

Out of scope -

• Race cars and tuned cars with large ammounts of additional equipment (that's for a wire in proteus or atlas)
• Non-standard engines in chassis
• Additional equipment beyond common mods to the chassis

Intended form factor - 80mm x 80mm up to 85mm x 85mm to suit the majority of cases but ideally as small as practical

Current list of parts dropped from Proteus:

• 4x lowsides (remove two VNLD5090) LS 9 - 12 routed to plugs
• 4x High/low (TC4427) IGN 9 - 12 removed and routed to pins
• Knock signal headphone jack () Line out removed from filtered 1 and 2
• Both ETB (TLE9201 only added if vehicle needs ) Removing ETB means routing Dis, Dir and PWM to pins adds 2 pins to total
• Both VR (board reconfigured for hall and MAX added if vehicle needs VR, also larger MAX chip can be used) VR1+ and VR2+ connected to input pins, VR- Removed from pins

Requirement to route 3.3v and 5v out of board for additional vehicle board equipment

Added keep alive voltage pin
