ESP32-C3-MINI-1U-N4是乐鑫(ESPRESSIF)推出的紧凑型表面贴装(SMD)无线模块,专为物联网(IoT)场景设计,整合了高性能RISC-V内核芯片与蓝牙5.0协议栈,兼顾小体积、低功耗与强通信能力,可满足工业、智能家居、户外设备等多场景的无线连接需求。
模块核心采用乐鑫ESP32-C3FN4芯片,基于32位RISC-V架构,运行稳定可靠。无线协议方面,支持Bluetooth 5.0(BLE),兼容蓝牙4.2及更早版本,同时工作在2.4GHz ISM频段——既保证了与现有蓝牙设备的兼容性,又能利用蓝牙5.0的长距离传输(理论最远可达300米)、低功耗广播等特性,适配电池供电的移动设备。
模块的硬件参数针对IoT场景做了针对性优化,核心指标如下:
模块提供丰富的外设接口,方便对接各类传感器、执行器与外围设备:
模块采用SMD(表面贴装)封装,尺寸仅12.5mm×13.2mm,体积小巧,可轻松集成到紧凑型设备(如智能手环、传感器节点)中;表面贴装工艺兼容自动化生产线,降低客户的生产难度与成本,适合批量部署。
ESP32-C3-MINI-1U-N4的特性使其适配多种IoT场景:
该模块凭借乐鑫成熟的芯片技术与完善的开发生态(如ESP-IDF开发框架、大量示例代码),降低了客户的开发门槛,是IoT产品实现无线连接的高性价比选择。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
