Casing/Enclosure Compatibility

The table below collect known information about casing and enclosure compatibility for the StarPro64 sbc.

Casing and enclosure compatibility for StarPro64

Casing/Enclosure	Compatible	Notes
ROCKPro64 PREMIUM ALUMINUM CASING	No	StarPro64 has two stacked ethernet ports, making it too tall.
Acrylic Enclosure	Partial	The screw closer to the LEDs and the one closer to the dip switches touch some components, potentially shorting or damaging them. Screw with a smaller head might work.

Bringup Notes

• Lup Yuen's StarPro64 bring up article section 1-7
• Boot DIP switches' labeling is the same as STAR64: "ON" means "0".
• Boot DIP switch 1 represents the least significant bit in the table at page 14 of the schematic.
