Info about cristals is needed

Hi guys,

I’m developing my own Cerberus hardware, compatible with the modules I bought.
My question is about crystals (don’t worry, not the RTC crystal). I can´t find the frequency of “Q1” (Cerberus board) and X2 (ENC28 Ethernet module). If it is not classified, and anyone wants to help me, please post the part number, or something.
Thanks

Crespi

Not sure I understand. The processor crystal you mean? That is 12Mhz

Hi Crespi,

Regarding X2… The standard crystal for ENC28J60 is 25MHz.

Thanks people.

There are many crystals with different load capacitance. Do you recommend some particular value?

The datasheet for the STM32F4 is your best bet.
