Maximum peripherals for nrf52840 that can be interfaced?

[Vishal Aditya]

We are evaluating the feasibility of a device using nrf52840 which requires below peripherals:

3 x SPI: For MCU to MCU communication + high-speed data transfer from sensors.

1 x I2S: For audio decoding/transmission

1 x I2C: For OLED

1 x USBD: For data transfer to PC/Client

1 x UART: For debugging purpose only

Please comment & give your suggestions if all above peripherals can work together in nrf52840 & how about nrf_drivers/sdk_config in ble_app_uart?

The Product Specification tells you how many of each hardware peripheral (SPI, I2C, etc) are available.

You will have to do the sums to see if there are enough pins!

Do you really need 3 separate SPI buses ?
