Pro boards
Pro boards are the catalog’s premium tier: branded hardware with rich built-in peripherals, emulated deeply enough to boot their factory firmware. They are part of the hosted catalog on velxio.dev.
M5Stack
Section titled “M5Stack”Free plan.
M5 Cardputer ADV
Section titled “M5 Cardputer ADV”
The ESP32-S3 pocket computer with keyboard and TFT. Boots the real M5 launcher firmware; type on the on-screen keyboard, run apps, use the speaker.
Get the real board on the M5Stack store.
M5Stack Core
Section titled “M5Stack Core”
The classic stackable ESP32 with 320x240 TFT and three buttons.

Pimoroni
Section titled “Pimoroni”Free plan.
Badger 2350
Section titled “Badger 2350”
The RP2350 e-paper badge. It boots the complete BadgeOS factory firmware: navigate the launcher with the A/B/C/UP/DOWN buttons, open the clock, badge and gallery apps, and watch the e-paper refresh the way e-paper really does.
Galactic Unicorn
Section titled “Galactic Unicorn”
The 53x11 RGB LED matrix (583 pixels) driven by an on-board Pico 2 W (RP2350), with the A/B/C/D and volume / brightness buttons.
Pico Plus 2 W
Section titled “Pico Plus 2 W”
Pimoroni’s RP2350B board in the standard Pico footprint (GP0..GP28 plus power), so any Pico wiring drops straight onto it. GPIO, UART, USB serial, I2C and SPI run; the CYW43 WiFi coprocessor and PSRAM are not emulated.
Seeed Studio XIAO
Section titled “Seeed Studio XIAO”Free plan.
XIAO ESP32S3 Sense
Section titled “XIAO ESP32S3 Sense”
The S3 with the camera module, PDM microphone and microSD.
XIAO ESP32C6
Section titled “XIAO ESP32C6”
WiFi 6 capable RISC-V C6 in the XIAO footprint.
XIAO RP2040
Section titled “XIAO RP2040”
The RP2040 XIAO with its NeoPixel.
XIAO RP2350
Section titled “XIAO RP2350”
The RP2350 XIAO — dual core at 150 MHz, Arduino C++ or MicroPython.
XIAO nRF52840 Sense
Section titled “XIAO nRF52840 Sense”
Nordic’s nRF52840 with a 6-axis IMU: tilt it from the Sensors button on the canvas toolbar. Bluetooth is not emulated.
Seeeduino XIAO (SAMD21)
Section titled “Seeeduino XIAO (SAMD21)”
The original XIAO, with a real DAC on A0.
XIAO RA4M1
Section titled “XIAO RA4M1”
The UNO R4 Minima’s MCU in the XIAO footprint, 12-bit DAC included.
XIAO MG24 Sense
Section titled “XIAO MG24 Sense”
Silicon Labs’ EFR32MG24 with a 6-axis IMU. The radio is not emulated.
XIAO nRF54L15 Sense
Section titled “XIAO nRF54L15 Sense”
Nordic’s nRF54L15 with a 6-axis IMU. The radio is not emulated.
XIAO IPS Display boards
Section titled “XIAO IPS Display boards”
Three carrier boards with a pre-soldered XIAO nRF52840 Plus, drawn front and back: the 0.96” (80 x 160, two buttons), the 1.14” (135 x 240, three buttons, Grove I2C) and the 1.47” Touch (172 x 320, capacitive touch, microSD). The glass is the emulated panel controller’s memory; the buttons, the IMU, the touch layer and the card all work, and Seeed’s own demo sketches run unchanged.
Espressif ESP32-C6
Section titled “Espressif ESP32-C6”Free plan.
The ESP32-C6 DevKit — the RISC-V WiFi-6 chip, with the same language trio (Arduino / MicroPython / ESP-IDF) as the rest of the ESP32 family.
DFRobot UNIHIKER M10
Section titled “DFRobot UNIHIKER M10”Paid plan required.
A Linux single-board computer with built-in touchscreen — documented with the Raspberry Pi family, since it shares the full-Linux workflow. Like the rest of that family, it is the one board on this page that needs a paid plan to run.
