Designing a custom pcb, we have a few questions, and maybe you could help a little bit.
On this Nordic design ,before proceeding to layouts :
- Can I skip pins 45/46/47 and not puting L2/L3 ? I did not see them on other designs.(what are they?)
- If I won't use NFC, can I skip all the parts on pins 11/12 and simply use them as outputs ?
- Can we locate the chip on one pcb side and the antena right on the other side beneath the chip? ( extreme size constrains on pcb..)
- Can I flash this design using nrf52 dev kit on the debug connector ?
Are there any specific pins that can't do specific things ? (I could see serial/I2C/SPI/PWM works on all of them)
Thank you !
