LCD Kit connection example
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
- Supports DDR2 / DDR3 / DDR3L memory interface expansion, meeting various expansion needs
- 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 DSI interface, USB-A port, Ethernet port, and speaker header, etc.
