This is an alternative POTI expander for the XAOC Devices / Batumi eurorack module. Instead of the original 3U 3HP format I designed a 1U [Intellijel format] version with a twist. Instead of the switch combination method I used a high quality 4-position rotary switch. I find this way cleaner as a design and easier to use as well.

The module is offered as a DIY KIT. It requires soldering for the rotary & toggle switch as well as the pin headers. I offer a PDF assembly guide but no customer support in case your module doesn’t work properly, although everyone with a soldering iron should be able to built it easily. It comes with every component you need to build this, as well as a ≈35cm ribbon cable to connect the expander with Batumi. The included cable is long in order to reach the 1U row in your case easily.
