June 28 P2: Footprint Assignment and Beginning PCB Design

After completing the schematic, I began with assigning footprints to all my symbols.

The 10uF capacitor and led have a 0603 footprint, and the remaining capacitors, fuses, resistors have a 0402 footprint. I used the easyeda2kicad script to get footprints for buttons, the wroom module, ldo, and usb-c receptacle. I did a lot of research on which footprints to use for which components, and also measured my current devboards to see what they use.

I then began designing my PCB.

I made it so the wroom module and USB are on opposite ends of the PCB. The height of the pcb is the height of the header pins + the height of the wroom module except for the antenna, which hangs over the edge.
The components near the USB-C receptacle are the LED, USB ESD, LDO, Fuse, Diode, etc. All things that make sure the power doesn’t blow up the chip.

I also began adding some of the traces for the header pins but then decided to wait until all the other important things were done.

Time spent this session: 2 hours
