ESP32 (classic)

The original dual-core Xtensa ESP32 — the workhorse of the catalog, with WiFi and Bluetooth available in the simulator.

Board Highlights
ESP32 DevKit V1 The standard 30-pin devkit; built-in LED on GPIO2
ESP32 DevKit-C V4 Official Espressif devkit, 38 GPIO
ESP32-CAM ESP32 + 2 MP camera module + microSD slot
Wemos Lolin32 Lite Compact, LiPo charger footprint

Languages: Arduino C++, MicroPython, ESP-IDF — switch with the toolbar’s language selector.

What works

Section titled “What works”
  • WiFi: join Velxio-GUEST and reach the real internet — see ESP32 WiFi.
  • Peripherals: GPIO, PWM (LEDC), ADC, I2C, SPI, UART, and the timer/interrupt machinery — your firmware boots with the real ROM log.
  • ESP32-CAM exposes its camera and microSD in the simulator’s component panels.
  • Web flash: push the same binary to a physical ESP32 over USB — how.

Notes

Section titled “Notes”
  • The first ESP-IDF/Arduino compile of a session is the slow one; later builds cache.
  • The built-in blink example (your first project) targets the DevKit V1.
