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.

WiFi 6 and Bluetooth module
Onboard 2.4GHz WiFi 6 and Bluetooth 5.2/BLE Bluetooth Module, Providing Stable Connection And Efficient Transmission

Reserved PoE Module Header
More Flexible for Power Supply


* the PoE module is optional, and the switch in the picture above is NOT included.
MIPI DSI 2-lane interface
Compact size, powerful performance, easy to drive large screens

* Supports up to 1280 × 800 @ 60Hz resolution.
Rockchip Matrix IO design
The Rockchip Matrix IO supports 98 multiplexed functions and allows flexible pinout configuration
