+2FIRE Ignition Add-On

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.

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.
