@roll_the_dice posted:I installed one in an Atlas 2 rail, but no smoke feature on the engine. I assume smoke could be used, but I don't have any steam engines to try it out on yet. If you look at the ESU manual (available here) it mentions a smoke unit for pin 19 (heater) and pin 20 smoke temp sensor. Hope that helps. Good luck.
I'm not happy that they don't support two motors. I do plan on contacting ESU and ask them to consider producing a 2L on the next generation or move the motor driver off the board entirely and just have motor enable, left motor PWM, and right motor PWM outputs OR provide a jumper on the board to disable the motor driver and a connector for the three aforementioned outputs. This does preclude usage to the back EMF capabilities to autopopulate the correspnding CV's, but, oh well. I can recover the PWM signals from the motor driver outputs but it's more work on my part.
