行業(yè)領(lǐng)先的射頻性能
ESP32-C3 集成 2.4 GHz Wi-Fi 和支持長距離的 Bluetooth 5 (LE)，有助于構(gòu)建覆蓋范圍更廣、射頻性能更強(qiáng)的物聯(lián)網(wǎng)設(shè)備。它還支持藍(lán)牙 Mesh (Bluetooth Mesh) 協(xié)議和樂鑫 Wi-Fi Mesh，在較高的工作溫度下仍能保持卓越的射頻性能。

Security
ESP32-C3 ensures that the availability of features, such as the RSA-3072-based secure boot and the AES-128-XTS-based flash encryption, can be used to build connected devices securely. The innovative digital signature peripheral and the HMAC peripheral provide a secure device identity for applications. Hardware acceleration support for cryptographic algorithms ensures good performance for the secure communication both in a local network and with the Cloud.

完善的安全機(jī)制
ESP32-C3 支持基于 RSA-3072 算法的安全啟動(dòng)和基于 AES-128-XTS 算法的 flash 加密功能，確保設(shè)備安全連接；創(chuàng)新的數(shù)字簽名模塊和 HMAC 模塊確保設(shè)備身份安全；支持加密算法的硬件加速器確保設(shè)備在本地網(wǎng)絡(luò)和云上安全傳輸數(shù)據(jù)。

Software Availability
ESP32-C3 is supported through Espressif’s open-source ESP-IDF that already powers millions of devices in the field. This ensures the availability of a robust SDK and tools, as well as an easy application migration path for developers. ESP32-C3 can also be used with an external host MCU, using ESP-AT and ESP-Hosted solutions.

成熟的軟件支持
ESP32-C3 沿用樂鑫成熟的物聯(lián)網(wǎng)開發(fā)框架 ESP-IDF。ESP-IDF 已成功賦能了數(shù)以億計(jì)的物聯(lián)網(wǎng)設(shè)備，并歷經(jīng)了嚴(yán)格的測試和發(fā)布周期。開發(fā)人員基于其成熟的軟件架構(gòu)，憑借對 API 和工具的熟悉，將更容易構(gòu)建 ESP32-C3 應(yīng)用程序或進(jìn)行程序遷移。ESP32-C3 也支持在從機(jī)模式下工作，可通過 ESP-AT 和 ESP-Hosted SDK 為外部主機(jī) MCU 提供 Wi-Fi 與 Bluetooth LE 連接功能。
