You can buy them on SeeedStudio. http://www.seeedstudio.com/depot/Automation-Board-p-2596.html
I have bought all of Seeeds stock in two purchases - 8 units in all. When I asked they explained to me that the product was end of life and they would not be producing more unless a volume was ordered. I may be able to order between 50 and 100 later in the year but for the moment I need another 3 or 4 to finish the first phase of our project.
I will talk them to check if they can produce more units and make available on their store.
Thanks for using our board.
All the best!
AB is back on Seeed. They still some units to sell.
Thanks for the heads up, visited the Seed site today - showing out of stock. Either not yet placed the stock online or someone got in before me
I will talk to them. They made available but I think they forgot to change the status.
Thanks Marcello - placed an order for 10 units today
