The Venom Breakout is the HONEY-standardized 50-pin breakout for the primary flight stack. It provides access to the primary data pins on the HONEY data bus, the power bus, and the primary CAN bus. It is implemented by a 1.27mm-pitch, 2-row connector, and is consequently also utilized using a set of 1.27mm-pitch dual-row ribbon cables.

Any board is free to implement the Venom Breakout, whose pinout & specifications are listed here in full.

The Venom Breakout was first introduced with the introduction of Viper, the Gen 1 HONEY breakout, which chose this format and pin-out as the standard breakout format for the HONEY Stack.

Venom Breakout is not alone -- there is also a Fang Breakout, which is also found on Viper.

Connector: Samtec SHF-125-01-L-D-RA
Cabling: Samtec FFSD-25-D-XX.XX-01-N

In the above, XX.XX denotes the length -- which can be custom as desired, in inches (2 inch minimum).

The specific pin out for Venom Breakout is the following, with the first row as the top, second row as the bottom, left to right as seen looking into the receptacle from the board-edge.
