Hi All,
Since I made an Arduweeny style module two months ago, some users pointed out to me that the Samtec socket strip is very expensive and out of stock, so it's impossible for them to make the module.
I changed the socket strip type. The new Mini Stick V2 bare PCB is available for sharing at Oshpark:

The schematic basically is not changed from the V1.
