Hi guys,
with my last PCB order i decided to add the System Blue Basic 22.2b with Piggyback 22.2c and Preamp 23.1.
Adding the official partlist from the directory to my last Digikey order worked like a charm.
Except one thing: the throughole components are not in there
All of them are more or less easy to identify on the pictures, but i got one simple problem.
Which quarz oscillators 8 / 25MHz do i have to use - the CL (or Belastungskapazität) on the board is 10pF, everything else results in a slightly lower or higher frequency. What about the capacity of the tracks etc., do i have to pay attention at them?
That would lead to a quarz with a CL > 10pF
As the system should be used for participation later on, i'd like to have all values as close as possible to the "detector kit".
I'd also buy a "throughole component kit" (as seen on the picture on limaps org hardware ) if that is the easier way
