 The result of this is that a single matrix consumed 3,8 amps at 5 volt. With 4 ESC's providing a total of 12 amps at 5 volts I should be easily able to power the mcu's and the matrixes.
 ## Assembly
+Here I started assembly of the drone. I printed the motor arms and screwed all the motors into them and soldered pogo pins to each to connect them to the esc's. Unfortanetly I don't know how to connect them yet because the wires aren't labeled. 2 motors need to spin left and the other 2 right for stability.

+I also saw during assembly that the drone body warped a bit but that isn't going to ruin the fun. It will still fly.

 ## Kaboom
 I accidentally killed an esp C6 due to short in between the PWM output pin of the mcu and the 5v inputs of all electronic speed controllers. That's 5V 12Amps running through the mcu. The first few tests I was lucky that I didn't plug anything into the shorted connector but when connecting everything the mcu got killed. I sadly can't repair the board since there is hot glue everywhere to keep the connectors on the board.

+Later on I realized I also killed my IMU. Because there wasn't any resistance between the 3v3 and the GND
