How to flash

Hi! I've just received my PCBs and I thought I could flash them using the USB port, but after checking out the schematic, it turns out i can only do it with the debug header.

  1. Is that correct? Is the USB port just for charging?
  2. What type of flashing device do I need?

Nevermind, I got some help on the ESPHome Discord server. I just had to hold the BOOT switch while plugging it in, after figuring out that there are contact traces from the D+/- pins on the USB header to the ESP32.
