so theres no need to complicate anything just to drive 4 led's LOL

Paul what boards was you saling for $25 to help get money up I missed out on it?
I would like to get one if theres any left

I highly doubt you need all 4 of those VLA modules to drive the IGBT's. What IGBT are you using? My guess is you could run 2 modules with 1 VLA. Might be able to run all 4 with 1 VLA. They are very powerful drivers. Let me know what IGBT u have and was it the VLA503?
