Can I power up?

[aloha]

hi,
The parts I ordered are still arriving one after another, but the parts I have on hand are enough to weld the main board. Excuse me: can I write bootloader and burn firmware for the Main board without connecting the RF board? Then power up and check the function of encoder and buttons?

Thank you

Yes. I have done it.
