乐鑫发布CoreBoard和Korvo开发板用于ESP32-S31
circuitrocks · 2026-05-26 · via DEV Community

乐鑫刚刚揭开了两款新开发板的面纱,它们的目标是乐鑫迄今为止最具雄心的芯片之一:双核RISC-V ESP32-S31。如果你一直在寻找一款结合了强大物联网功能和边缘人工智能能力的开发板,这对开发板值得你仔细研究.

ESP32-S31有什么大不了的?

这款新芯片在异构设置中集成了两个RISC-V核心。其中一个运行速度最高可达320 兆赫用于性能要求高的工作负载,而另一个则省电,用于日常微控制器任务。乐鑫将其定位在高级物联网、机器学习推理、计算机视觉和智能音频领域——所有这些都来自一个带有60个GPIO引脚的芯片.

在无线方面,你将获得2.4GHz的Wi-Fi 6。 GHz,蓝牙5.4经典版和低功耗版,再加上一个支持Thread和Zigbee的802.15.4无线电。甚至还有一个集成的千兆以太网MAC,这对于ESP32来说并不常见。在RAM方面,你将看到512 KB的片上SRAM,以及一个八位250 MHz DDR总线用于外部PSRAM。其中一个核心还配备了128位数据路径和SIMD,用于并行数值计算。

核心板与Korvo:选择你的口味。

ESP32-S31-功能核心板-1 是主力。它搭载 16 MB 的 PSRAM,可选 8、16 或 32。  8MB 闪存,一个板载麦克风,一个单声道音频编解码器,带放大器输出的扬声器输出,有线以太网,USB 2.0 高速 Type-A 和全速 Type-C 端口,一个 40 引脚 GPIO 头,一个内置电流测量头,以及一个用户可寻址的 RGB LED。如果您想从传感器集线器到网络控制器进行任何原型设计,这是理想的选择。

ESP32-S31-Korvo-1 用人机界面(HMI)设备替换了以太网。相同的模块——这次带有 16 兆字节闪存——连接到Omnivision OV3660摄像头、4.3英寸800×480 LCD显示屏、两个独立扬声器输出、两个模拟麦克风、四个用户按钮、一个RGB LED、一个microSD插槽,以及USB Type-A和Type-C接口。基本上是一个现成的智能显示参考设计.

自己动手搭建

想马上开始其中一个的修改?你需要 ESP32-S31 模块本身,并且根据你要克隆的板子:一个 Omnivision OV3660 摄像头模块,一个 4.3 英寸 800×480 LCD 屏幕,模拟麦克风,一个单声道音频编解码器和扬声器驱动器,一个 microSD 卡插槽,以及 USB Type-A 和 Type-C 端口。价格和一般可用性尚未确认,但 Espressif 的 CoreBoard 和 Korvo 文档页面已经上线。
