Hey all,
As promised, I compiled a bill of materials list [1] of all of the hardware parts (and their prices) for the repeater nodes I've built thus far. Actually itemizing it all, I've spent more than I expected, but I've also learned a lot in the process. I have a few solid ideas on how to bring costs down for future nodes while still keeping them robust.
I'll try to keep this spreadsheet updated moving forward. Let me know if you have any questions about the choices I made!
