Allied Component Works open hardware largely adopts the Digilent, Inc. PMOD form factor to provide direct and low cost solutions for evaluation of semiconductor component products.  A number of semiconductor manufacturers have also adopted PMOD for development boards of their own, making it a fairly widely recognized approach.  The hardware and software items discussed in this thread are all open source and low complexity by design, closely following the documentation and intent of the original component manufacturers.

Allied Component Works open hardware is also available on Tindie!
