1,3V regulator supply decoupling capacitor missing ! (nRF52832 )

[Tizana]

Hi,

i was about to solder my PCB that contain an nRF52832 and i've noticed that i didn't have C9, C10 capacitors.

 C10 is the 1uF decoupling capacitor for the 1.3V regulator supply (DEC4) and C9 is the 4.7uF capacitor connected to the VDD.

so i'm wondering if i solder the PCB without these components the nRF will work ?
and can i replace the C10 with 100nF capacitor available ?

thanks,

Hi,

 C9 can be 100 nF, and the board might work without it even. C10 must be populated, and it must be 1.0µF.

 

Best regards,

Andreas
