香蕉派开源硬件开发板 Banana Pi BPI M2Pro Amlogic S905X3 主板

Banana Pi BPI-M2 Pro是Banana Pi公司于2021年推出的下一代单板机。它采用Amlogic S905X3四核Cortex-A55 (2.0 XXGHz)处理器。板载2GB LPDDR4内存和16GB EMMC存储，支持2个USB 3.0接口，1个千兆网口。板载RT8821CU wifi&BT。1 HDMI输出 905X3是晶晨半导体旗下最新的8K智能家庭影音芯片，采用四颗64位ARM A55架构 CPU芯片，集成G31图形处理器，支持8K视频解码和8K视频输出，运行开放的安卓9.0系统和Linux系统。

BPI-M2 Pro与香蕉派 BPI-M2+ 一样大小，接口也一样，所以可以使用BPI-M2+的外壳。

主要特点:

• Amlogic S905X3 四核Cortex-A55 (2.0xxGHz)处理器
• Mali-G31 GPU图形处理器
• 2GB LPDDR4内存
• 16GB eMMC 板载存储.
• 板载RT8821CU wifi&BT
• 2 USB 3.0 端口
• 1 GbE 千兆网口
• HDMI 输出

• 硬件信息

• 香蕉派BPI-M2 Pro 与香蕉派 BPI-M5 一样采用Amlogic S905x3芯片方案，但在尺寸与接口上完全与香蕉派 BPI-M2+一致，用BPI-M2+做产品的客户，可以直接升级替换。
