Mega 8 controlboardFinally got around to make a PCB to control the Stellex synthesizers. I got a bit frustrated trying to use KiCAD, placing aribtrary vias is something KiCAD could improve as well as arcs in copper layers. I was going to use eagle, but found http://easyeda.com that worked fine, at least for something this simple.
I am not very found of ”cloud” solutions, but being able to do routing wherever you are is appealing…
The boards are not anything special, just a AVR mega 8 and two voltage regulators. I included points to connect to most unused pins, perhaps I will use this for some more generic tasks as well.
Hopefully I will get the boards today, they are on the way from dirtypcbs with DHL. Shipping is more expensive than the pcbs, but I didn’t want to wait for the HK post shipping…
This is just to get started, future plans include stabilization of the internal 10Mhz reference oscillator with GPS and/or an OCXO.
