Supported boards
Velxio simulates boards from seven families. Some run entirely in your browser; larger ones run on Velxio’s cloud emulators — you don’t have to do anything different, it just works when you press Play.
| Family | Boards | Languages |
|---|---|---|
| Arduino / AVR | UNO, Nano, Mega, ATtiny85 | Arduino C++ |
| ESP32 classic | ESP32 DevKit, DevKit-C v4, ESP32-CAM, Lolin32 Lite | Arduino C++, MicroPython, ESP-IDF |
| ESP32-S3 | ESP32-S3, XIAO ESP32-S3, Arduino Nano ESP32 | Arduino C++, MicroPython, ESP-IDF |
| ESP32-C3 | ESP32-C3, XIAO ESP32-C3, C3 SuperMini | Arduino C++, MicroPython, ESP-IDF |
| RP2040 / RP2350 | Raspberry Pi Pico, Pico W, Badger 2350 (Pro) | Arduino C++, MicroPython |
| Seeed XIAO | ESP32S3 Sense, ESP32C6, RP2040, RP2350, nRF52840 Sense, SAMD21, RA4M1, MG24 Sense, nRF54L15 Sense, the IPS Display boards | Arduino C++ (MicroPython on the ESP32 and RP2040/RP2350 ones) |
| STM32 | Blue Pill, Black Pill, F4 Discovery, Olimex H405, Netduino | Arduino C++ |
| Raspberry Pi (Linux) | Zero, 1, 2, 3, 4, 5 | Python on a full Linux terminal |
The STM32 and Raspberry Pi (Linux) families run on Velxio’s emulation servers and need a paid plan; they carry a PRO badge in the component picker. Every other board, including the branded ones like the M5Stack Cardputer and the Badger 2350, runs on the free plan — see plans.
Each board has its own page in this section with its pinout, supported languages and quirks.
