The new version of the Busboy 9000, a small format, 9 position shrouded header busboard for eurorack cases.

With capacitor filters, indicator LED’s per rail and (optional) onboard 5v regulator.
Size: 16.5 x 4.2 x 1.2 cm (without 5v regulator)  or 16.5 x 4.2 x 3 cm (with 5v regulator and heatsink)

With oblong solder pads on the headers for easy soldering!

note: if you build the version with the 5v regulator on it:
I’ve added a “voltage regulator to heatsink” isolation package. This consists of a plastic screwholder, a mylar film and a screw + bolt.
The metal of the regulator cannot touch the heatsink, as this might cause problems. So use the isolation package!
You must also buy some cooling paste and apply this to the heatsink on the side that touches the regulator.
This will help to keep the temperature low.

This busboard is suitable for small systems. Likewise, you can connect 1 or 2 modules that need 5v (when using the voltage regulator on the PCB)
If the regulator + heatsink gets too hot, you might need a bigger heatsink! (or less modules that need 5v)
