Developer Jan Ostman let us know about a new PCB design for building DIY drum modules – the rev2 PCB for the DR-55/CR-4/RW DIY Module.

He describes it as “Perfect as a first DIY build.”

The PCB comes with a presoldered SMD SOIC-8 version of the chip, so just jacks and simple components need to be soldered to the board.

The board is designed to be built as a 6HP Eurorack module, but can also be adapted for other projects.

It’s available for $45. A prebuilt module version is also available.
