Buchla inspired 248 MARF Expander panel & PCBs.

This module allows you to expand from 16 steps to 32 steps.

Please note that this Expander module requires a small modification on 248 MARF rev2.1 PCBs. Please also make sure to download the latest 248 MARF firmware version 2.5. No modification needed on 248 MARF PCBs with revision #2.3 and higher. Firmware version 2.5 is required and can be downloaded from the MARF product page.

The PCBs are matte black with golden solder pads, the panel is made of brushed aluminum with countersunk holes for M3 screws for PCB mounting. Graphics are silkscreened.

The BOM can be found next to the “Description” tab.


The PCBs are sold unpopulated and need to be stuffed by yourself. Basic electronic skills are needed.

We will not take any responsibility for damages or injuries when building and running the offered PCBs or full sets.
