## Full pin number chart
Chart consist all pin numbers used in Speeduino Firmware for Miata / MX5 PNP boards. Pin numbers are Arduino Mega pin numbers. This chart can be used as a guide when setting unused default outputs for some other use.
| Pin name | Pin number | Description |
|---------------------------|-----------------------|-----|
| pinInjector1 | 11 | Output pin injector 1
| pinInjector2 | 10 | Output pin injector 2
| pinInjector3 | 9 | Output pin injector 3
| pinInjector4 | 8 | Output pin injector 4
| pinInjector5 | 14 | Output pin injector 5
| pinCoil1 | 39 | Pin for coil 1
| pinCoil2 | 41 | Pin for coil 2
| pinCoil3 | 32 | Pin for coil 3
| pinCoil4 | 33 | Pin for coil 4
| pinCoil5 | 34 | Pin for coil 5 PLACEHOLDER value for now
| pinTrigger | 19 | The CAS pin
| pinTrigger2 | 18 | The Cam Sensor pin
| pinTPS | A2;//TPS input pin
| pinMAP | A5 | MAP sensor pin
| pinIAT | A0 | IAT sensor pin
| pinCLT | A1 | CLS sensor pin
| pinO2 | A3 | O2 Sensor pin
| pinBat | A4 | Battery reference voltage pin
| pinDisplayReset | 48 | OLED reset pin
| pinTachOut | 49 | Tacho output pin (Goes to ULN2803)
| pinIdle1 | 2 | Single wire idle control
| pinBoost | 4;
| pinIdle2 | 4 | 2 wire idle control (Note this is shared with boost!!!)
| pinFuelPump | 37 | Fuel pump output
| Note that there is no stepper driver output on the PNP boards. These pins are unconnected and remain here just to prevent issues with random pin numbers occurring
| pinStepperEnable | 15 | Enable pin for the DRV8825
| pinStepperDir | 16 | Direction pin for DRV8825 driver
| pinStepperStep | 17 | Step pin for DRV8825 driver
| pinFan | 35 | Pin for the fan output
| pinLaunch | 12 | Can be overwritten below
| pinFlex | 3 | Flex sensor (Must be external interrupt enabled)
| pinResetControl | 44 | Reset control output
| pinVSS | 20 |
| pinIdleUp | 48 |
| pinCTPS | 47 |
