Question about System Blue parts. - kevinmcc - 2016-05-06
I am not able to source the 25 Mhz crystals from a US source that have same specs exact specs from the bit of looking I have done.
Is there anyway you can make both crystals SMD on a future revisions of the board and include them already mounted?

Let me suggest this for a moment... the 'release' production has been slightly delayed due to a parts issue, so you might wait and see what revisions are made in the actual factory build. The 8mhz came as installed, on the early 'test' releases. Alternative is to 'order' all items 1-18, rather than just the boards... there wion't be a lot of difference in costs, if you figure shipping, etc...
Meantime, in U.S... try

If those will work, I think I can find some.
Those have slightly different specs than the ones listed and I did not know what the tolerances were for the loading capacitance and resistance were.
Thanks for the reply.
