WiFi & IoT overview

ESP32 boards in Velxio come with simulated WiFi: your firmware sees a network, associates, gets an IP address over DHCP and can talk to the internet — the same sketch that runs on your desk runs in the simulator.

In this section:

• ESP32 WiFi — how the simulated network works, which chips support it, and WiFi from Arduino and MicroPython.
• MQTT and HTTP — connect your simulated board to real brokers and APIs.
• Web flash — when you’re happy with the project, flash it to a real ESP32 over USB straight from the browser, no toolchain installed.
