Luckfox Lyra RK3506G2 Linux Micro Board with Triple-Core ARM Processors

Luckfox Lyra is a cost-effective Linux-based micro development platform built on the Rockchip RK3506G2, providing a simple and efficient development environment.

The board features multiple high-performance interfaces, including MIPI DSI, RMII, and USB, making it suitable for various application scenarios. The low-speed interfaces utilize the Rockchip Matrix IO design, supporting the multiplexing of 98 functional signals on GPIO pins.

Additionally, it allows the flexible combination of PWM, UART, I2C, SPI, and I2S for quick development and debugging.

Specifications

Version and Pinheader options

Highly integrated and powerful performance

• Tripe-core ARM Cortex-A7 32-bit core, with integrated VFP to support single- and double-precision floating-point operations
• Built-in ARM Cortex-M0 MCU design, supports SMP and AMP configuration
• Built-in 128MB DDRL3 for multi-core applications
• The low-speed interfaces adopt Rockchip Matrix IO design, which allows rich function signals to share the limited chip pins, making peripheral circuit adaptation more flexible
• Built-in audio and video codec, supports multiple audio inputs and outputs, providing high-quality audio playback and recording functions

Easier to develop

Integrates TF card slot, DSI interface and USB connector

MIPI DSI 2-lane interface

Compact size, powerful performance, easy to drive large screens

* for reference only, please refer to the Package Content for the detailed part list.
Supports up to 1280 × 800 @ 60Hz resolution.

Rockchip Matrix IO design

The Rockchip Matrix IO supports 98 multiplexed functions and allows flexible pinout configuration

Optional for 256MB SLC NAND FLASH

Provides a better user experience

* Only Luckfox Lyra B versions with 256MB Flash, while the Luckfox Lyra versions require an additional TF card (NOT included) for storage.
