How to connect USB-C to PCB (used for power)

I designed a pcb with 60 leds, controlled by a ESP32. This is powered via an USB-C connector. I followed these instructions:

  • VBUS Pins (A4, A9, B4, B9) are joined and routed through:

  • A PTC fuse (MF-LSMF300/24X-2, C719172) for overcurrent protection

  • A TVS diode (SMF5.0A, C1509112) — cathode to VBUS, anode to GND — for surge/ESD protection

  • CC1 (A5) and CC2 (B5) each have a 5.1 kΩ pull-down resistor to GND to enable 5V output from USB-C

  • GND pins (A1, A12, B1, B12) are connected to a solid GND pour on the bottom layer

  • VCC (5V) is poured on the top layer, and GND vias are used to connect top-side components to bottom GND

My question is: are these instructions correct? And if so, can you judge from the image if I’ve correctly attached these components?

Thanks!!!

Your best bet for an answer is to upload the sketch (the .fzz file, upload is 7th icon from the left in the reply menu.) Pictures are essentially useless in evaluating a circuit as they lack important details.
