Posted: Wed Oct 01, 2014 4:37 pmHappy to buy the chip from you and to pay for the knowledge to change it, however I do have a fully working unit which is an adaption of your own 56i board essentially slightly modified to make the tracks wider for ease of DIY pcb construction and its split into two boards. It works perfectly. It did cost more to make than buying a module from you and it wasn't to save money but more fun in making it myself. If it only requires a few mods to make it work I'm quite happy to do them, and would prefer not to be left behind on the upgrades.
