The selection-header is 6 pins wide. The second pin from each end connects directly to the power rail. The first and third pins from each end are a particular voltage. Therefore, to select a voltage, you must jump together either the: 1st & 2nd pins, 2nd & 3rd pins, 4th & 5th pins, or 5th & 6th pins. '''Be careful not to accidentally jump the 3rd & 4th pins -- which can permanently damage the HONEY BMS.'''

In chart form, this is:

As you can see, there are two pins for each rail that are connected to the rail. Hence, one should only use one shunt per power rail selector; because otherwise, you'd short together two power nets.
''It is worth noting that the headers for the left & right power rails are mirrored.''

In the case of two or more ProtoBees, one can connect the flight stack to the STACK IN connector, then connect the second ProtoBee to the "STACK OUT" connector of the first -- daisy chaining them together. This allows combining any number of ProtoBee's together, with only one cable going to the main fligh stack.

The Venom Breakout is broken out onto a set of headers, which can then be used for the project being tested on the ProtoBee. There are two options for how to utilize this -- one can either solder down a set of vertical male headers, to allow the use of female-male jumpers for testing & changing things easily, OR one can forego soldering male headers down, and instead use breadboard jumper wires to solder directly from the breakout to the breadboard.

There are two options for how to utilize this -- one can either solder down a 2x25 female socket, to allow the use of male-male jumpers for testing & changing things easily, OR one can forego soldering the socket down, and instead use breadboard jumper wires to solder directly from the breakout to the breadboard.
The latter is encouraged for well-designed systems that want to be very solid and ready for flight; however, understandably, many systems are to be tested and might have issues, and a more flexible arrangement using headers & jumper wires may be preferrable.

Additionally, the HONEY Power Bus is broken out onto its own dedicated set of 2x6 headers, to be used as needed, in the same manner.

The pinout for the breakout is well designated on ProtoBee for reference. To understand the functionality of each signal, see the HONEY spec.
