All modules by FreeModular are open source. To make each DIY module more accesible for beginners, designer's website also includes a manual and assembly instructions, firmware source code, quick-order CSV files for components that can be uploaded to direct-order manufacturers, and faceplate/PCB files that can be uploaded to on-demand PCB manufacturers. Some modules are also available as kits or assembled modules through designer's Etsy.
