关键特性

  • 160 MHz RISC-V , 407.22 CoreMark
  • 400KB SRAM (TCM) + 384KB ROM + 4MB SPI Flash
  • 2.4 GHz Wi-Fi4 & BLE 5.0
  • 2 × UART
  • QFN32(5*5)

ESP32-C3 的成本对标早期ESP8266,同时沿用乐鑫成熟的物联网开发框架ESP-IDF

官方提供各种模组型号,ESP32-C3-MINI-1 模组尺寸小巧 (13×16.6 mm),可支持最高工作温度 105℃。ESP32-C3-WROOM-02 模组支持105℃的最高工作温度,与 ESP-WROOM-02D 和 ESP-WROOM-02 模组引脚兼容,方便用户升级到 ESP32-C3。

升级产品ESP32-C6 主要支持Wi-Fi6(HT20 MCS-9)和更多的协议栈,如和matter、thread共存。

降本方案ESP32-C2由于资源限制无法实现复杂应用,在一定程度上无法发挥积累的协议优势,而简单的控制器应用的可替换方案太多,不太建议使用(门槛较高)。

竞品BL602 拥有更高的主频和更丰富的外设,在MCU应用领域优势突出,但Wi-Fi的通信带宽相对更弱(72.2Mbps),双方在开源生态构建上,后来者BL602也逐渐被认可,被开发者适配到了各种开源项目中。
