Brief
WARG has our own internal connector standards for lots of things, however, generally a lot of peripherals connect to a Pixhawk and we are starting to build custom hardware intended to replace the Pixhawk and custom hardware intended to replace Pixhawk peripherals. Consequently this document contains the standards. If WARG does not have a specific connector selected for something please default to using these standards.
