I think it is the time to explain the step-by-step on how to convert UDOO x86's NGFF M.2 B-key (a.k.a. NGFF socket 2) to a regular sized PCIe slot. Step 0) buy the following adapter card from fleaBay. The $9 one shipped faster (in about 3 weeks.) The $3 one took longer (about 50 days.) Here is the board close-up. The M.2 connector is M-key (socket 3) and the PCIe connector is PCIe x4 (only 2 lanes are used even the board is for M-key 4-lane PCIe.) I'll explain the rationale in later posts. ccs_hello (In fleaBay, search PCI-E 4X Female to NGFF M.2 M Key Male Adapter Power Cable with Converter Card http://www.ebay.com/itm/311414541676?
