=== Master Breakout ===
In addition to the Venom Breakout, Viper also includes a larger, 56-pin 2.54mm (standard) pitch connector known as the Master Breakout -- or, more formally, the '''Fang Breakout'''.
The ''Fang Breakout'' breaks out the remainder of what the Viper Breakout was unable to breakout, or what was deemed inessential for a payload to have access to. This includes the secondary CAN Bus and some additional avionics GPIO pins.
The Fang Breakout, at time of writing (Aug 10, 2017) has no impending implementation scheme. It exists in the first revision of the HAB Breakout to facilitate two things -- one, the possible eventual need to break out the additional remaining pins, and, more importantly, two -- to enable directly using female jumper wires to tap signals directly from Viper, by providing a standard-pitch connector that can be both directly tapped or cabled.
The Fang Breakout pinout is very similar to the Venom Breakout, with some slight alterations:
