In this thread I want to introduce my design and hope to get any comments or hints to improve it. If anybody knows a finished design I would also welcome evidence (if it is commercially available or can I use the CAD files).
Here is my Idea:
I have designed a round PCB with four mounting holes for the ESC32. The ESC32 PCB should fit perfectly in the hole and at the bottom and top border I have lands to connect the ESC32 lands with my PCB.

The motor cables can be soldered directly to the lands on my PCB and the ESC32 PCB.
There are 4 3-pin Headers for the PWM signals and also 4 6-pin Headers for a FTDI cable. Thanks to this I can (re) flash the ESCs in my PCB with no need to unmount them.
The complete bottom layer is connected to the Lipos V+, and the top layer to GND. I have 4x6mm lands on top and bottom to connect the Lipo.
There are 4 mounting holes with 45mm distance to mount the whole PCB on the frame.
I'm thinking about an additional jumper for I2C and CAN connection, but in that case I have to redesign the PCB. To have a big copper area for V+ and GND from the Lipo it is necessary to route the I2C and CAN bus at the border of the PCB. Actually there is not enough space for that so I have to move the holes for the ESCs away from the PCB border.
As I wrote in the beginning, any comments are welcome.
Thanks for your attention
