PoE Support: Power over Ethernet (PoE) functionality is specific to designated Pi series models and requires a compatible PoE power source. Matrix IO: RM_IO pins allow for flexible pin-multiplexing; refer to the specific pinout diagram for each model to ensure correct hardware mapping. Core3506 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. It 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.
