Flash the DarkSec Deck firmware onto your ESP32-C5 — Waveshare C5 LCD or LilyGo T-Dongle — straight from the browser. No drivers, no toolchain.
Plug the deck in over USB and click CONNECT, then pick the deck's serial device (look for Espressif USB JTAG/serial debug unit) in the browser dialog. If the chip won't sync, hold BOOT while plugging it in.
