Reference Designs

Free-to-use Complete Product Prototypes

These public domain designs are provided ‘as is’, with no warranty expressed or implied. Each design generally consists of a schematic, Altium and Gerber files for PCB fabrication, and a Bill of Materials (BoM).

Designs which make use of the imp001 are not intended or recommended for commercial use, but are ideal for early prototyping and platform evaluation. Because the imp002 is no longer in production, reference designs based upon it have now been archived.
