Note: Please bare with me, this is my first PCB design!

The intention of this PCB is to attach an HLK2410 millimeter wave 24 GHZ radar module presence sensor to a USB type C power with as little extra space as possible.

While doing so, I realised that there is enough space below the HiLink Module to also add a 3.3V voltage regulator, so a microcontroller and other sensors can be powered directly from the same USB connection.

I also often read that people are frustrated with the small 1.27mm pins, so I added normal 2.54mm pin holes to the PCB, so you can attach it easily to any default breakout board and can more easily solder your wires or whatever to the relevant pins.
