AM68 Computer

This project is a AM68 computer were Linux can be deployed onto. The circuit board is made in Altium CircuitMaker.

This is a continuation of STM32-Computer. Here a better processor and better RAM memory will be used.

Operating system to the board

Here is AM68-OS system for the board.

Notes

To produce this board, the manufacture need to have these minimum capabilities:

• 0.1 mm minimum electrical clearance between traces pads and vias
• 0.09 mm minimum electrical clearance between BGA pads and traces
• Capability to cut the edge of the BGA pads if the minimum electrical clearance between BGA pads and traces are above 0.09 mm
• 0.09 mm minimum width of traces
• Via-in-pad according to IPC 4761 Type VII (Epoxy filled and capped)
• Via hole size of 0.3 mm and via diameter of 0.4 mm
• Impedance control: JLC04161H-1080

I have been using JLCPCB as the manufacturer for this.
