ESP8266EX 产品概述
一、概述
ESP8266EX（乐鑫）是一款高度集成的 2.4GHz Wi‑Fi 收发器 SoC，适用于资源受限的物联网终端。芯片集成天线开关、射频 balun、功率放大器（PA）、低噪声放大器（LNA）、滤波器与电源管理模块，外部电路简洁，可独立运行或作为从机由主 MCU 驱动。片上集成增强型 Tensilica L106 32‑bit 内核与 SRAM，乐鑫提供完整 SDK 和示例代码，加速产品开发。
二、主要特性
- 频率范围：2.4GHz ~ 2.4835GHz（典型 2.4GHz）
- 发射功率：21.5 dBm，数据速率可达 72.2 Mbps
- 接收灵敏度：-91 dBm
- 工作电压：2.5V ~ 3.6V，工作温度：-40 ℃ ~ +125 ℃
- 集成度高：PA、LNA、滤波、天线开关、射频 balun、PMU
- SDK 支持丰富，可通过 GPIO 扩展传感器与外设
三、电气与射频参数
- 发射电流（典型）：120 mA；接收电流（典型）：50 mA
- 数据速率：72.2 Mbps（物理层速率视 Wi‑Fi 配置而定）
- 功耗与电源设计需考虑发射峰值电流并做好去耦和稳压（建议在 3.3V 方案中使用低 ESR 电容近芯片端）
四、接口与封装
- 外设接口：I2C、I2S、UART、SPI（多种串行接口便于与传感器、音频或主 MCU 通讯）
- 封装：QFN‑32‑EP（5×5 mm），利于小尺寸 PCB 方案
五、典型应用与设计要点
- 适用场景：智能家居、无线传感器节点、智能插座、可穿戴设备、音频传输等 2.4GHz Wi‑Fi 应用。
- 设计要点：合理布置射频地与接地孔、短且匹配的天线走线、稳压与去耦电源网络、遵循参考布局以保证射频性能与 EMI 合规。
ESP8266EX 以其高集成度、成熟的软件生态和低成本特性，适合快速开发小型 Wi‑Fi 物联网产品。
Request for quote
Send RFQ
Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
