'''Cobra''' is the first generation of HABEES HONEY Expander Boards. Expander Boards ae HONEY-compliant boards that allow expanding the capabilities of a HONEY flight stack in a rapid-prototyping manner. That is, one can test new circuits or projects readily in a HONEY flight stack without making a HONEY compliant board.

Be certain to not jump more than one voltage on a given rail -- this could cause permanent damage to the BMS or Teensy. You may select different voltages for each of the power rails, if desired (ie +5 on one, +12 on the other), or you can set the same voltage source for both.

The Teensy socket, if used, also comes with an included MicroSD socket for data logging (at the top of the board), and a CAN Transceiver, for interfacing with the HONEY stack. The implementation of these, however, results in the utilization of Teensy pins 3 & 4 (for CAN) and one for the microSD chip-select. These pins, are, therefore, off-limits for use as they are already reserved for these functionalities.

The breakout for the Teensy pin right-angled header is as so, with the first row being the top row, and the second row being the bottom row; left to right as viewd down the Cobra PCB from the top.

There is, additionally, a smaller pinout for the HONEY stack -- providing access to all of the most important data and power lines in the HONEY stack. Due to lack of space on the interior of Cobra, this breakout faces the exterior edge.
