ESP32-PICO-D4 产品概述
ESP32-PICO-D4是乐鑫科技（ESPRESSIF）推出的一款集成式无线收发器，采用SiP（系统级封装）技术整合WiFi、蓝牙低功耗（BLE）及核心射频单元，专为IoT、WiFi与蓝牙通信场景设计，具备高集成度、稳定性能与宽环境适应性，是中低端无线设备的主流选型之一。
一、核心集成特性
该产品以SiP封装实现高度功能整合，无需额外射频组件即可完成无线通信：
- 集成WiFi（802.11b/g/n协议）与蓝牙低功耗（BLE）模块，支持双向收发；
- 将基带处理器、射频前端、存储单元等整合至7×7mm尺寸的QFN48封装内，简化PCB设计流程，降低物料成本与开发难度；
- 采用SMD（表面贴装）工艺，适配自动化生产，提升量产效率。
二、无线性能参数
针对2.4GHz ISM免授权频段优化，性能覆盖多场景需求：
- 频段范围：2.412GHz~2.484GHz（全球通用2.4GHz频段），典型应用频率为2.4GHz；
- 发射能力：最大输出功率20dBm，覆盖范围广，适合家庭、小型办公场景的全屋无线覆盖；
- 接收能力：灵敏度达-97dBm，弱信号接收能力强，可有效抵御多设备共存的电磁干扰（如智能家居多设备场景）；
- 传输速率：WiFi模式下支持150Mbps高速传输，满足高清视频、大文件同步等数据密集型需求。
三、接口与供电设计
提供灵活的外设扩展与供电方案：
- 接口：支持I2C、SPI等常用数字接口，可直接连接温湿度传感器、显示屏、存储模块等外设，快速扩展设备功能；
- 供电：工作电压范围2.7V~3.6V，兼容3.7V锂电池（常见便携式设备电源）与固定直流电源，适合电池供电的可穿戴设备及固定安装的智能家居设备。
四、封装与应用场景
小尺寸封装适配多类IoT设备需求：
- 封装：QFN-48-EP（带暴露焊盘），7×7mm紧凑设计，暴露焊盘增强散热性能，避免长时间工作过热；
- 典型应用：
- 智能家居：智能灯、插座、窗帘控制器；
- 可穿戴设备：智能手环、手表（BLE通信+WiFi数据同步）；
- 工业物联网：传感器节点、数据采集器（宽温适应工业环境）；
- 消费电子：无线耳机、游戏手柄（辅助WiFi低延迟通信）；
- 智能家电：电视、空调的无线遥控器。
五、环境适应性
具备工业级环境耐受能力：
- 工作温度范围-40℃~+85℃，可在低温（北方户外、冷库）、高温（厨房、工业车间）环境下稳定运行；
- 抗干扰性强，适配多设备密集的办公区、工业现场等复杂电磁环境。
总结：ESP32-PICO-D4凭借高集成度、稳定无线性能、宽温度范围与小尺寸封装，成为IoT、WiFi及蓝牙场景的高性价比选择，广泛覆盖智能家居、可穿戴、工业物联网等领域。
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.
