Raspberry Pi 树莓派产品系列说明

系列文章目录


前言

        随着我们产品线的不断扩展,要了解所有不同的 Raspberry Pi 板可能会让人感到困惑。以下是 Raspberry Pi 型号的高级分类,包括我们的旗舰系列、Zero 系列、计算模块系列和 Pico 微控制器。

        Raspberry Pi 电脑分为几个不同的系列:

  • 旗舰系列通常简称为 “Raspberry Pi”,提供高性能硬件、完整的 Linux 操作系统和各种常用端口,外形尺寸与信用卡差不多。
  • Zero 系列提供完整的 Linux 操作系统和基本端口,价格实惠,外形小巧,功耗低。
  • 计算模块系列(通常简称为 “CM”)提供高性能硬件和完整的 Linux 操作系统,外形小巧,适合工业和嵌入式应用。Compute Module 型号的硬件与相应的旗舰型号相当,但端口较少,没有板载 GPIO 引脚。用户应将计算模块连接到单独的底板上,该底板可提供特定应用所需的端口和引脚。

        此外,Raspberry Pi 还生产 Pico 系列微小、多功能的微控制器板。Pico 型号不运行 Linux,也不允许使用可移动存储器,而是允许通过将二进制文件闪存到板载闪存上进行规划。


一、旗舰系列

        型号 B 表示有以太网端口。型号 A 表示成本较低的型号,外形较小,没有以太网端口,内存减少,USB 端口减少,以限制电路板高度。
