MCU and RF module are both NRF5340. Do I need both or should I just use the RF module as MCU and RF Transmitter?

Very sensitive Mixed signal PCB. EEG (Brain wave sensor). 0.010mv sensitivity



I have seen multiple examples of EEG PCB's where they have a MCU and a separate RF module.



Considering the fact that the RF module (MDBT53) is literally a NRF5340 with an antenna, should I just use that to process everything



The Primary MCU is also a NRF5340



I believe the reason they have two separate ones if to reduce noise and to split the Bluetooth transmission internal noise from the primary MCU



ADS1299 is the big ic on top layer that does all the ADC. The microcontroller is for processing the data.

A brainwave-controlled FX pedal? COOL!

For the time being, I'm sticking with good ol' potentiometers and fuzz circuits with a handful of transistors...

It's for a brain activated burst button switch

Awesome.

But what is it you want the Neuro-Busrt to do?

I need it to saturate my tube screamer capacitor

I think your thinking of a kill switch. But a Neuro-kull switch would...
Ooooohhhhhh.
