I guess I’ve already answered your question through email. For those who are interested: OSBo (OpenSprinkler Beagle) is now discontinued due to the rather small demand. However, we do have a lot of OSBo PCBs and offer them for sale at a great price: http://rayshobby.net/cart/pcbs/pcb_osbo11
They don’t come with components so if you want to build these you need to follow the schematics and buy components yourself.
Sorry, OSBo has been discontinued. The demand is not high enough to justify for the production cost. Not that I don’t like BBB or anything, it’s just that RPi is much more popular and has much larger community support.
