- 工作电压：3.0 V ~ 3.6 V
- 发送电流：约 310 mA；接收电流：约 63 mA
- 存储：4 MB Flash，2 MB PSRAM
- 天线形式：板载 PCB 天线
- 封装尺寸：SMD，20.5 × 15.4 mm
- 工作温度：-40°C ~ +85°C
- 接口：SPI、I2S、USB、I2C、UART
三、功能特色
模块集成高性能单核 WiFi MCU，支持 USB 设备接口与丰富的外设总线，适合音频流（I2S）、传感器总线（I2C/SPI）、串口通信（UART）等应用。内置板载 PCB 天线，免去外部天线设计，缩短开发周期。4 MB Flash 能满足固件与文件系统存储，2 MB PSRAM 提供运行时内存扩展，利于复杂协议与缓存需求。
四、典型应用
- 智能家居网关与控制面板
- 无线传感器节点、远程测控终端
- 语音/音频传输与处理设备（基于 I2S）
- 工业通信、数据采集器与消费类智能设备
五、设计与使用建议
- 电源：模块需稳定 3.3 V 供电，建议使用低噪声 LDO 或 DC-DC，并在电源输入处布置输入滤波和充足的去耦电容（如 1μF+0.1μF）。发送高峰期电流达 ~310 mA，需确保电源与走线能力。
- 天线与布局：保留天线周围的空白区，避免金属或大量地铜覆盖；参考厂商天线走线与地平面建议以保证射频性能。
- EMC/ESD：在 I/O 口加入必要的 TVS 或静电保护措施，USB 接口处按规范增加共模扼流器与滤波。
- 外设与 Flash/PSRAM：开发时确认 Flash 与 PSRAM 的时序配置与驱动支持，合理分配存储用于 OTA、日志与缓存。
- 调试：模块支持 USB 接口，可用于开发调试与固件下载（视出厂配置）。
六、封装与环境参数
模块采用 SMD 封装，尺寸 20.5 × 15.4 mm，便于自动贴片生产；工作温度范围宽（-40°C 至 +85°C），适合室内外与工业环境。模块由 ESPRESSIF（乐鑫）提供，在设计量产前建议向供应商索取参考电路、封装图与天线参考布局以完成最终硬件验证与认证准备。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Sourcing availability signal
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Examples of how common component sourcing requests are organized.
Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.
The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
