Here you can find all schematics and PCB layout data for the WizFi250-EVB and the WizFi250-H Interface adapter.
On the EVB we use two 2×11 pin 50mil pitch socket and pin headers to make the WizFi250 removable.
We put the SMD type WizFi250 module on a Interface adapter board (that is than named WizFi250-H).
The pin headers have a distance of exactly 17mm.
