Description
This replaces the stepper module output to add two ignition outputs and a relay output.
Includes unsoldered header pins to allow for cheap envelope shipping.
NOTE: The mounted output resistors are 47 ohm, a different value may be recommended for your coil/ignition module.
NOTE: UA4C vC2 and later do not have a stepper socket any longer, because stepper control is built in. So these cannot be used on those boards.
Step pin – Ignition channel 1 – B1
Direction pin – Ignition channel 2 – A1
Enable pin – Relay Driver, 650mA rated – B2
Big thanks to Ash (vandea05) for the idea.

Hello, is it necessary to make any correction in the code for the 2 outputs to work? Is it necessary to run the computer with the cam phase sensor? to work on 6 cylinders? what would the instructions be? greetings and thanks
Weaver –
Yes. You must edit the pin definition for the board that you plan to use it with. The substitutions are in the product description. If you plan to run sequential fuel or spark, then yes you must have a phase sensor of some sort. Please keep in mind that the Arduino MEGA can only support a combination of 9 spark and fuel channels total.
