Thank you, that looks promising. 5 + 10 days is a bit though. Might be worth it to just wait 30 days in that case
I am super sorry for being such a noob, but can 
be used to socket the board? And if yes: Do I solder the ones with pins only on one side to the pcb and the other ones to stick into the holes and solder to the nice!nano?
Where to buy 301230 battery in Europe (Norway) with fast shipping
I forgot to buy batteries for my new split keyboard. Is there any good place to buy the 301230 3.7v 110mah battery, to get it within a week in Norway, or is it expensive to not buy it from China with 30 day shipping? If it is not possible to buy it: Are there any other good replacements which are compatible with the nice!nano and Ferris Sweep?
Thank you! It seems I might be able to just start the build process. Is it easy to install the battery later? I would assume I might need to remove the nice!nano and reinstall it? Would I then need to desolder?
Using Ferris Sweep + nice!nano with only one battery
I made a mistake while ordering the parts for the Ferris Sweep: I only ordered one 301230 battery. I ordered the other one, but the >1 month delivery time is a bit long. I am wondering if it is possible to solder and build the keyboard now, while only installing battery in one of the sides, and use the only side only with USB-C. If yes, I have two more questions:
- Which side should I install the battery in? From my understanding, one of the sides usually works as a "hub" for the other side
- Is it easy to add the battery to a already assembled keyboard in the future?
- Are there any good tutorials for assembling the wireless variant of the Ferris Sweep? I have mostly been able to find resources for the wired versions.
