#31495
updated the pin listing for the new stacked pcb model.


case 10:
#ifndef SMALL_FLASH_MODE //No support for bluepill here anyway
//Pin mappings for user turtanas PCB
pinInjector1 = 32; //Output pin injector 1 primary pcb pin 25
pinInjector2 = 34; //Output pin injector 2 primary pcb pin 13

pinInjector4 = 38; //Output pin injector 4 primary pcb pin 11
pinInjector5 = 24; //Output pin injector 5 secondary pcb pin 11
pinInjector6 = 26; //Output pin injector 6 secondary pcb pin 12

pinInjector8 = 30; //Output pin injector 8 secondary pcb pin 13
pinCoil1 = 52; //Pin for coil 1 secondary pcb 14
pinCoil2 = 50; //Pin for coil 2 secondary pcb 1
pinCoil3 = 48; //Pin for coil 3 secondary pcb 3
pinCoil4 = 42; //Pin for coil 4 secondary pcb 2
pinTrigger = 18; //The CAS pin primary pcb 10

#44443
made a more simple 100*120cm board
8x injector drivers (2 with flyback diode)
6x ignition outputs (tc4427)
3x general relay drivers (2n2222)
separate flyback line
onboard map
tps,map,iat,clt,o2
ignition and trigger lines on ribbon cable connectors separately

will put the files out when i get my proto tested.

Is it tested yet?
What did you test it on?
It's so small for a 1 sided PCB, well done.

Please is a magic word, or just about anything about you.
Who are you, where are you from and so on.
Like, beeing respectful to people just the way we behave in real life.
