Tiny302 pc board design

After the successful fabrication of Tiny302 prototype and a working monitor running on the Tiny302 prototype. It is time to put the design in a pc board. To minimize cost, the pc board form factor is 100mm x 100mm. This is a tight board, all components barely fit in the small form factor. The schematic is created with WinDraft, and the board is layout using WinBoard. As a part of the WinBoard package is license & interface to the Specctra autorouter (version 8–this is a 20-year old software, after all). The board is manually placed and then autorouted with the Specctra router in 2-layer. Specctra router is extremely fast, the autoroute is done in less than 5 minutes.

Use the naming convention provided by Seeed Studio, the routed design files are zipped and uploaded to Seeed Studio and proofed using their on-line gerber viewer.
