Need of decoupling capacitors for STM32WB5MMG

[sumit809]

Hi,

I'm using STM32WB5MMG and placed it in the top left corner of the PCB as recommended. The component assembly is top side only so I can't place the decoupling capacitors for VDD, VDDA, VREF+.

 Also, the schematic of Sparkfun's MicroMod Processor using STM32WB5MMG has a Note: "Decoupling capacitors are integrated onboard the module." So, I'm confused now. However, I've enough space to add 4.7uF Capacitor which is recommended to eliminate ripple on power supply.

So, is it okay to completely drop these 100nF decoupling capacitors from the schematic itself which are shown in MB1292 (STM32WB5MMG Discovery Kit)? Will it make a difference for being there or not in this module's case?

Thanks & Regards,

Sumit

The datasheet says a 4.7 uF is all you (might) need:
