SMD prototyping board for making that quick prototype. Designed to fit in the 5cm^2 limit of the cheapest elecrow offer Designed with Altium Designer, the used gerbers for ordering are in the "Protoboard.zip"
Stuff that can be better:
- Add solder resist around the pads
- Make a special region for QFN and other packages with elongated pads for easy access
- Make regions with VIAs to access power pads on the bottom side of packages
- Include common connectors(USB, DSUB) on PCB border
- Check more footprints if they fir the grid, if not perhaps change the grid
- Test other grid patterns(log, X/Y-different size)
- Go to 4 layer and allow power supply over the two core layers for easier prototyping
