Module with nrf52840 and external 32Mhz exist?

Hi,

I will be happy to know if there is a module with external 32Mhz?

All the module I found has internal 32Mhz.

Thanks,

Zvika

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,

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,

 

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.
