Tri-core ARM Cortex-A7 32-bit core, integrated VFP, supports single-precision and double-precision floating-point operations. Built-in ARM Cortex-M0 MCU design, supports SMP and AMP configurations. Built-in 128MB DDRL3, can meet the application requirements of multi-core operation. The low-speed interface adopts Rockchip's Rockchip Matrix IO design, which allows rich multiplexing functions to share limited chip pins, making peripheral circuit adaptation more flexible. Built-in audio and video codec, supports multiple audio input and output, and provides high-quality audio playback and recording functions.<br><br>Processor: Tri-core Arm Cortex-A7 (1.2Ghz) + Arm Cortex-M0 Memory: 128MB DDR3L USB: USB OTG2.0 x 2 Screen interface: MIPI DSI 2-lane GPIO: 24 Rockchip Matrix IO pins The product appearance and printed words may vary depending on the batch, but this does not affect use.
