本文档比较了同一 {IDF_TARGET_NAME} 系列的 AT 固件在支持的命令集、硬件、模组方面的差异。
本节介绍以下 {IDF_TARGET_NAME} 系列 AT 固件的区别：
.. only:: esp32 - ESP32-WROOM-32_AT_Bin（本节简称为 **WROOM Bin**） - ESP32-WROVER-32_AT_Bin（本节简称为 **WROVER Bin**） - ESP32-PICO-D4_AT_Bin（本节简称为 **PICO-D4 Bin**） - ESP32-SOLO-1_AT_Bin（本节简称为 **SOLO-1 Bin** - ESP32-MINI-1_AT_Bin（本节简称为 **MINI-1 Bin**） - ESP32-D2WD_AT_Bin（本节简称为 **D2WD Bin**）
.. only:: esp32c2 - ESP32C2-2MB_AT_Bin（本节简称为 **ESP32C2-2MB Bin**） - ESP32C2-4MB_AT_Bin（本节简称为 **ESP32C2-4MB Bin**）
.. only:: esp32c3 - ESP32-C3-MINI-1_AT_Bin（本节简称为 **MINI-1 Bin**）
下表列出了官方适配的 {IDF_TARGET_NAME} 系列 AT 固件默认支持哪些命令集（用 |icon-green-check| 表示）、默认不支持但可以在配置和编译 ESP-AT 工程后支持的命令集（用 |icon-orange-check| 表示）、完全不支持的命令集（用 |icon-red-cross| 表示），下表没有列出的命令集也为完全不支持的命令集。正式发布的固件见 :doc:`../AT_Binary_Lists/index`，已适配但未发布的模组固件，需要自行编译。自行编译的固件无法从乐鑫官方服务器进行 OTA 升级。
