routing an nrf52 in qfn48 with 0603 passives was not really a good idea in hindsight. very cramped. #embedded

@3nt3 Random notes from looking at this very briefly:
- The antenna should probably be at the board edge and not enclosed in copper
- The GND point of the antenna shouldn't have thermals
- Nordic is very peculiar w.r.t. how the antenna shunt cap (C13 in your case) should be grounded, check section 53.8 in the data sheet (it always seemed a bit cargo-culty to me but that's most of EE for you)

@3nt3 (sorry if you were aware and this simply wasn't done yet. Not trying to be a smart ass here but you mentioned this was new ground for you and I thought this might be helpful)
bro i swear this has everything from the reference design why do i still have 30 capacitors to place 😭

i think because of the fucking battery charging circuitry i for some reason wanted to have instead of just using a FUCKING POWER BANK LIKE THOSE THAT ALREADY HAVE CHARGE CONTROLLERS
