Luckfox Core3506 Core Board Based On Rockchip RK3506B Chip, Onboard 512MB DDR3L, Integrates Triple-core ARM Cortex-A7 and ARM Cortex-M0 Processors










Available Options
Based on the Rockchip RK3506B chip
The Core3506 is a core board based on the Rockchip RK3506B chip with high performance and high expandability, designed to simplify hardware development. Adapting various interfaces via castellated holes, such as MIPI DSI, RMII Ethernet interface, and USB, etc. which is suitable for various application scenarios. The low-speed interfaces utilize Rockchip Matrix IO design which supports multiplexing 98 function signals on GPIO pins, allows for flexible configuration of interfaces like PWM, UART, I2C, SPI, and I2S for quick development and debugging. Enables quick design verification or direct integration into products, thereby shortening the R&D cycle. Provides option of onboard 8GB eMMC storage to meet different storage requirements.
