'''Viper''' is the first generation HONEY Breakout Board. Viper breaks out most of the important signal and power lines from the HONEY stack Data Bus & Power Bus, as well as the CAN Bus, to enable connecting to the HONEY flight stack remotely, over cable.

As of August 10th, 2017, all HONEY flight stacks require Viper as the bottom-most (stack-terminating) board. This makes Viper a FCC (Flight Critical Component). This is both for physical and electrical reasons -- Viper is the only board with a non-stackthrough data bus, making it the choice for the bottom-most board. This was previously the BMS, due to the need for enough space for the battery pack -- however, the maximum spacing between flight stack boards has since increased to 20mm, allowing the BMS to be on the stack interior, and necessitating an alternate stack-terminating board -- Viper was chosen. Necessarily having Viper in a Flight Stack also guarantees any stack can be debugged using the master breakout, or expanded using payload breakouts.
