Model & package intelligence
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
Available for RFQ
Technical data
For datasheets, package documents, compatible-part guidance, or other technical resources, contact WMSIC customer service. Availability is confirmed case by case.
Support Micro SD Card,Micro SDHC card (high-speed card)
The level conversion circuit board that can interface level is 5V or 3.3V
Communication interface is a standard SPI interface
Control Interface: A total of six pins (GND,VCC,MISO,MOSI,SCK,CS),GND to ground,
VCC is the power supply,MISO,MOSI,SCK is the SPI bus,CS is the chip select signal pin;
3.3V regulator circuit: LDO regulator output 3.3V as level converter chip,Micro SD card supply;
Level conversion circuit: Micro SD card into the direction of signals into 3.3V,MicroSD card toward the direction of the control interface MISO signal is also converted to 3.3V,general AVR microcontroller system can read the signal;
Micro SD card connector: yes since the bomb deck for easy card insertion and removal.
Positioning holes: 4 M2 screws positioning hole diameter of 2.2mm,easy to install positioning,to achieve inter-module combination;

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.
