+So I will have 2 power systems in my drone. High voltage and low voltage. High voltage 16,8V will be for the motors while the 5v will be for the MCU's and the LED matrixes.
+
+I found out from the page from the ESC's that they output 5v at 3 amps each. Which is in total $$5V \cdot 3A \cdot 4ESC = 60Watts$$
+
+In one of my projects earlier I have ran 2 LED matrixes from a 60 watt power supply and it could easily power them. The mcu's don't consume a lot of power so the power situation should be good.

 What this function does is generate PWM values in software which is super inefficient. The esp32C6 according to it's datasheet supports 6 seperate PWM clocks in hardware.

 So I wanna use these to reduce the overhead and so the loop doesn't have to run 20 times a second but faster making the drone respond faster. To use these I need to use this library.

 ## Generative design
 Online I saw a lot of organic designs that where created by generative design.

 I think the main reason was heat and the coating on the motors evaporating causing a chain reaction.
 
+## Cables
+The drone needs lots of cables to get power to the places where they need to be. I first started out by laying out everything that needed to be connected.
+

+I first wanted to solder all the joints together but then I remembered how it looked in the past and then decided on using clips.

+After cutting cables and soldering for a while I made this cable harness.

+I still need to make a new board for both MCU's. The flight controller and the matrix controller.
+
+## New board!
+### Layout
+So my new board needs to handle 60 watts of power and a lot of wiring. So I am first going to make a rough sketch of where I want every connector.
+
+![alt text](image-35.jpg)
+
+I first came up with this. But then I realized how complicated this wiring on a one side board is going to be. So I split it up in 2 boards and then I will stack them on top of each other with standoff screws.
+
+![alt text](image-36.jpg)
+
+### Schematic
+I made both boards in the same file.
+![alt text](image-39.jpg)
+The upper board is the flight controller and the bottom board the matrix controller. I made them in the same file so I could easily copy over the edge cuts so I could stack the boards above each other.
+
+#### Flight controller
+* 4 outputs for ESC's
+* One communication pin to other Matrix controller with power and ground
+* Input BNO085
+
+#### Matrix controller
+* Communication from flight controller
+* 2 output LED Matrixes
