ESP32-S3-WROOM-1
基于 ESP32-S3 的通用 Wi-Fi + BLE MCU 模组,板载 PCB 天线。
乐鑫基于 ESP32-S3 的通用 Wi-Fi + BLE 模组,板载 PCB 天线,存储变体见下表。 在 MCUID 的硬件链——芯片 → 模组 → 板卡——中,本页持有模组事实:变体、模组级引脚条件与板卡兼容性。芯片能力在 ESP32-S3 芯片页;排针、修订与接口在板卡页。
从板卡开始:ESP32-S3-DevKitC-1——上手路径见首烧指南。
模组决定什么
- 变体后缀编码内存(N = flash、R = PSRAM)。GPIO 35–37 是否被内部 flash/PSRAM 通信占用取决于变体——判定表见 GPIO 35/36/37 指南。下方模组记录按官方原文陈述该条件。
- 存储变体——下表列出官方变体及其官方来源;flash/PSRAM 容量是本模组的事实,不是芯片的。
- 兼容板卡——下方列表与板卡页来自同一份数据。

gpio.occupied_by_internal_storage | 35, 36, 37 | 条件:variants with Octal SPI flash or PSRAM (not all WROOM-1 variants) | verified · cc40 · 2026-11-08 | DevKitC-1 guide v1.1 | Official guide note: for boards with Octal SPI flash/PSRAM embedded ESP32-S3-WROOM-1/1U modules, GPIO35-37 are used for internal communication between ESP32-S3 and SPI flash/PSRAM and are not available for external use. The restriction is NOT valid for all WROOM-1 configurations; variant-level storage interface types are not listed for every ordering code in the guide. |
