H-Bridge components and assemblies come in a multitude of sizes, shapes, capacities, and costs.  When we designed our BrainStem® Moto 1.0 Module, we needed to establish a standard interface for the many various h-bridges that can be used with the board.  We also wanted to establish the standard so that future boards built by Acroname or others could also use any existing bridges.

This standard aims to be as policy free as possible, while still allowing a great deal of flexibility in the options of motion control feedback and additional I/O that may be associated with an h-bridge in a robotic system.

The standard is based on the widely used 0.1" spacing of most through-hole PCB parts allowing easy insertion into breadboards and other prototyping areas.
