Description Waveshare Luckfox Lyra RK3506G2 Linux Micro Dev Board is a compact Linux development platform built around the RK3506G2 triple-core ARM Cortex-A7 processor with an onboard ARM Cortex-M0. It is designed for embedded Linux development, smart display projects, automation control, multimedia terminals, and compact industrial HMI applications that need a small board with practical display, USB, and GPIO expansion. This Luckfox Lyra board integrates 128MB DDR3L, MIPI DSI 2-lane display output, USB OTG 2.0 x2, and Rockchip Matrix IO with 24 multiplexed pins. The Basic variant uses a TF card for storage, while the 256MB Flash variant adds onboard W25N02KV 256MB SLC NAND FLASH for a more integrated Linux deployment workflow. Features RK3506G2 triple-core ARM Cortex-A7 + ARM Cortex-M0 heterogeneous processor design. 128MB DDR3L onboard memory for Linux development and multi-core applications. Two storage paths: TF card on the Basic version, or 256MB SLC NAND FLASH on the 256MB Flash version. MIPI DSI 2-lane interface supports displays up to 1280 x 800 @ 60Hz. USB OTG 2.0 x2 for power, data, and peripheral expansion. Rockchip Matrix IO with 24 multiplexed pins for PWM, UART, I2C, SPI, CAN, ADC, and GPIO functions. Built-in audio and video codec for playback and recording workflows. Compact development-ready layout with USB Type-C, BOOT, RESET, and ACT-LED.

Product List Basic Luckfox Lyra x1 256MB Flash Luckfox Lyra B x1 Other Content Rockchip Matrix IO design gives the Luckfox Lyra series a flexible pin multiplexing structure for embedded projects that need PWM, UART, I2C, SPI, CAN, ADC, and GPIO on a compact Linux board. Variant selection matters. The Basic version is intended for users who want to boot from a TF card, while the 256MB Flash version adds onboard SLC NAND FLASH for a more integrated storage setup. Pin definition and onboard layout are especially important when planning display wiring, USB expansion, and GPIO multiplexing on this RK3506G2 Linux micro development board. Resources Luckfox Lyra Wiki Luckfox Documentation Center Luckfox GitHub Repository Rockchip Matrix IO Reference RK3506 Datasheet FAQ What is the difference between the Basic and 256MB Flash versions?The Basic version uses a TF card for storage, while the 256MB Flash version adds onboard W25N02KV 256MB SLC NAND FLASH. Can this board drive a DSI display?Yes. The board provides a MIPI DSI 2-lane interface and supports displays up to 1280 x 800 @ 60Hz. What makes Rockchip Matrix IO useful on this board?It allows multiple functions such as PWM, UART, I2C, SPI, CAN, ADC, and GPIO to be multiplexed across limited pins, which helps when designing compact embedded systems. Is a TF card included with the Basic version?No. The official specification states that the Basic version uses a TF card for storage, and the TF card is not included.
