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:

They don’t come with components so if you want to build these you need to follow the schematics and buy components yourself.
