Hello everyone, I'm new to pcb designing and I'm having trouble choosing the right crystals for atmega328pb-au and nrf24l01p-r. I looked into many different example schematics and decided to use these crystals in these arrangments (photos attached), I'd like to ask if I'm using the correct crystals and in correct arrangements? (HCM4916000000ABJT for nrf24l01 and CSTNE16M0V530000R0 for atmega328pb)
Also in the last photo I've included an example of nrf24l01 schematics and it says 50ohm RFIO. I assume this is where the antenna goes and I'd like to ask if I'm supposed to use a 50ohm resistor or an antenna of 50ohm or what does 50ohm RFIO mean?
Any help is appreciated.
