Hi, I am working on a project including an NRF24L01+ with PA. The MCU I use on my PCB is a ESP32S3. I previously created a NRF24L01+ with PA PCB connected to my system with pin headers like the ones you buy online and it worked like a charm. I decided to include the NRF24L01+ circuit directly on my main PCB, copy/pasting the first design that was working fine on the dedicated small PCB but its not working at all. My PCB has 4 layers (1=signal+ground, 2=GND, 3=3V3, 4=signal+GND). I just read in the data sheet that power supply to NRF24L01+ has to be dedicated only to this chip and not feeding any other components. Actually, I'm supplying the ESP32S3 with the same power supply. So, my question is, should I use an "Isolated DC/DC Converters" like the IES0103S3V3 from XP Power to isolate the power circuit of the NRF24L01? Also, I'm using the same ground plane on layers 1, 2 and 4 for all components including the NRF24L01+ and the ESP32S3. Should I use a dedicated ground plane for the NRF24L01+?
