Hi,

Why do you need to use an external source when there already is an internal one? Please see this post, and note that this assumes there is not already a crystal on the XC pins.

Best regards,

Andreas

Hi Andreas,

We accutal not found any module certified with 32Mhz external , so we will go with module base nrf52840 ( internal 32Mhz) and Co-MCU Nero fit with oscillator TXCO.

Thanks,

Hi,

Do you mean internal/external to the module, or internal/external to the SoC (which is on the module).

nRF52840 needs a crystal to run the radio, I would expect most module manufacturers to include this on the module.

Best regards,

Andreas
