This is a redesign of Chameleon USB FX2 (cusbfx2). Board dimension and pin assignment are all the same as cusbfx2, but changing some parts and move all components to top layer.
You will need good sodering skill to complete this project.
Lots of 0402 package resistors and capacitors need to solder
Lots of TSSOP/TQFP/SSOP components need to solder

MAX II chip (EPM570T100C5N) is not easy to find right now so basically find a working MAX II chip (make sure is a EPM570T100) first, then order PCB and others parts.
