Sanni,
I would like to appreciate all of Your work You've done for the whole community. I ordered 10 boards of Cartreader and SDcart adapter and I would like to contribute to community some how. For sure I don't need all the 10 boards,so I want to share 8 with You guys.
So if You don't mind to save a bit on PCB manufacturing I can send one to You (once I receive them) with just cost of shipping which shouldn't be more then 6USD from Russian Federation.
