NRF52 pcb design

[oliverhu]

during the pcb design of nrf52, is it compulsory to totally copy your reference pcb layout . since our case need to design a small size device, so i have to modify the pcb design(not change the component ,just rearrange some components) and make it tight.

Yes, this is OK. You should have no problem doing this. Since the nRF52 has an on-chip balun there isn't much high frequency stuff you can mess up. But as a rule dont touch any of the high frequency (2.4 GHz) components unless you really know what your doing. So if you are using a reference example that has a pi tuning network for the antenna dont mess with that.

but clocks, decoupling capacitors, dc/dc converters no problem.. just be careful with antenna/radio stuff.
