There are 3 extra SX48BD-Gs over at Schmartboard and any forum member is welcome to one each until they run out.
PM me and I will give you a one time only code word to get one from Schmartboard guy.
You pay Schmartboard $6 for PCB and $6 to solder it in an oven plus 3 or $4 mailing cost.
This is a stamp as in common use of the word.
All SX48's pins are brought out to headers on each side of the PCB.
Then you are on your own.You put it on a breadboard and get it to run.
