Printed Circuit BoardIf you would like to have a professionally manufactured printed circuit board for the opentherm gateway, there are three options:
Buy a circuit board at a webshopKiwi electronics sells printed circuit boards, kits, and fully assembled gateways.
VDR Elektronica also offers the OpenTherm Gateway PCB on their web site.
Note: I have no relationship with these webshops and get absolutely no benefits from the PCB's or gateways they sell. So, in case of problems with any item bought at a webshop, you will need to get in contact with their customer service.
Buy a circuit board from another userThe following users have indicated they have some left-over boards they are willing to sell:
Let me know if you have some left-over boards from a batch and want to be listed here for other people to get in touch with you.
Order a batch of circuit boardsYou can order a batch of ten circuit boards for around $33 (including shipping) from seeedstudio.com or iteadstudio.com. Both charge $24.90 for the boards, but shipping costs are a little bit lower at seeed ($7.80 versus $8.98). However, itead will do a 100% E-test at no extra charge, while seeed by default only does a 50% E-test and charges $10 extra for a full 100% E-test.
Here is a graphical representation of the gerber files for the circuit board.
