Kit Selection
Highly integrated and powerful performance

- Triple-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 DDR3L 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

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.
