I need help with the minimal circuit board requirement of the custom board with nRF52832 and nRF52840 for wireless and SPI communication.
I need to read vales over wireless communication and show values on display via SPI communication.

Hi,
The nRF52 series has internal pullups/pulldowns on each GPIO pin, so nothing external is needed for SPI to work. Just connect the SPI pins SCLK,CS, MISO,MOSI to a slave/master and it should work.
Do you have a specific question regarding this?
