Appendix I – Powering the KK2.1.X
The KK2.1.X has two 5V power busses.
The first 5V bus is common across the receiver inputs, output 1 (M1) and the programmer port. This bus powers the KK2.1.X processor and needs to be as clean as possible (i.e. no noise from servos).
The second 5V bus is common for outputs 2 to 8 (M2 to Monly.
You shouldn’t connect the two 5V busses together as any noise on outputs 2 to 8 will then be present on the KK2.1.X CPU power supply.
ESCs don’t generally need a 5V power supply but servos do. Therefore, if a servo is connected to M2 to M8, it will also need a 5V power supply. Usually, an ESC with a 5V BEC will be connected to M1 which will power the receiver and the KK2.1.X board. Servos on the M2 to M8 5V bus will need another ESC with a 5V BEC to be connected to M2 to M8. Note, you could run the M2 to M8 power bus at 6V if you wanted to.
In general, only one BEC should be connected to M2 to M8. In the case of a quadcopter, you will have three ESCs connected to M2, M3 & M4. If they have switching BECs, their 5V wires should not be connected together on the M2 to M8 power bus. Therefore, remove all 3 red wires from the servo connector and put some heat shrink over each one (leave one BEC on M2 to M4 if you need to power a servo on M5, M6, M7 and/or M
Some ESCs don’t have an internal BEC so you will need to use an external UBEC. If you already have an ESC (without a BEC) plugged into M1, you have the following options to power the KK2.1.X and receiver.
* Connect the UBEC to a spare receiver channel. This will power the receiver and the KK2.1.X via the cable that connects the receiver and KK2.1.X.
* Use the Mixer Editor and copy the M1 settings to M5 (or any spare output). Connect the ESC for motor 1 that your would have connected to M1 (output 1) to the new motor output you just configured. Now, you can connect your UBEC to M1.
* Use a servo Y lead to connect both the ESC and UBEC to M1.
Some ESCs have low current BECs which have been known to “brown out” when large motor currents are drawn. If this happens, the KK2.1.X will reboot and therefore results in a crash. If you are concerned that this could happen, you should use an external UBEC and connect as above.
