3 knob HVAC control upgrade

Any idea on V2 production retail pricing? I hope it works flawlessly as I am just about to start modifying my center console for a double din. So the faster to market the better!

No idea on pricing yet - mounting fascia and housing will probably be 3D printed parts - not designed yet. Working on the first board assembly so I can test functionality - after that will be the pretty stuff!

Progress update! Have the first circuit board almost ready for the 3 ***** to be soldered on. Did a first test of the Red/Blue button activation lighting - works as expected, but seems pretty bright without going through the button lens. Still a couple mods to the lighting circuit before I finish the soldering work on this board, then it will be used to finalize the programming and verify the relays work as I want. Also will verify the temp control **** works with the stock setting motor and sensor string. The details learned from this board will be incorporated into the V2 design.
I have found the 2007-2009 Nissan Sentra HVAC ***** are functionally identical to the 2010-2012 *****, and have the same mounting, and light tunnel underneath - in fact, the whole board is almost identical. The 07-09 ***** are slightly smaller OD (middle row in the pics below) and tapered more, so these will probably be the best option for a straight swap of the stock slider unit - will still be a tight fit, but that comes down to the mounting and front trim fascia design.

No orders until this is fully tested. Electronics design is not my forte - so want to be confident it will not cause problems in the field. I will keep moving forward, and update with progress reports.
