This video provides a comprehensive review and demonstration of the new Luckfox Lyra Zero W, a highly affordable $17 single-board computer. The board features a Rockchip RK3506B SOC with three ARM Cortex-A7 cores, 512MB of RAM, 256MB of onboard SPI flash, an SD card slot, and 2.4 GHz WiFi, all in a Raspberry Pi Zero form factor.
The review covers the initial setup process, demonstrating a quick boot into a pre-installed Buildroot OS via an ADB connection. The presenter then shows how to flash new images and successfully installs and runs a full Ubuntu 22.04 environment from an SD card, including WiFi configuration. Performance is evaluated through power consumption measurements (idling at ~130mA) and a custom Python benchmark, which shows significant performance gains over typical microcontrollers. The video culminates in a demonstration of the board's ability to drive a 10.1-inch DSI touchscreen display and run a full, albeit software-rendered, XFCE graphical desktop environment, highlighting its impressive versatility for its low price point.
A Deep Dive into the $17 Luckfox Lyra Zero W: Setup, Benchmarks, and Desktop Demo
0:00 Impressive Value: The video introduces the Luckfox Lyra Zero W, a $17 single-board computer (SBC) capable of running a full Ubuntu environment with WiFi and 40 GPIO pins.
0:44 Hardware Specifications: The board is detailed, featuring a Rockchip RK3506B SOC (3x ARM Cortex-A7 cores), 512MB RAM, 256MB SPI flash, SD card slot, USB-C, and a MIPI DSI interface in a Pi Zero form factor.
3:23 Quick and Easy Setup: Out of the box, the device boots in under 12 seconds into a Buildroot OS and is immediately accessible via ADB over a single USB-C cable.
4:53 Low Power Consumption: Power measurement shows the device idles at approximately 130mA (around 0.65W at 5V), making it suitable for low-power applications.
6:14 Flashing and OS Options: The video demonstrates how to flash a new Buildroot image to the internal SPI flash and also showcases a custom-built Ubuntu 22.04 LTS image running from an SD card.
11:30 WiFi Configuration: A step-by-step guide is provided for configuring and connecting to a WiFi network on both the Buildroot and Ubuntu operating systems.
13:19 Performance Benchmarking: Using a custom Python script, the SBC's performance is benchmarked, showing it is significantly more powerful than microcontroller-class devices like the RP2040 and ESP32-P4.
17:21 Driving a DSI Display: The board is shown to be capable of driving a 10.1-inch, 1280x800 DSI touchscreen display directly with no extra configuration needed.
18:46 Full Desktop Environment: The video demonstrates the installation and use of a full graphical desktop (XFCE via xubuntu-desktop) on the device, showcasing a usable, albeit software-rendered and laggy, desktop experience.
9:49 & 20:35 Giveaway and Availability: The presenter announces a giveaway for four of the boards and notes that they are available for purchase from his online store.
