Offers SPI, USB, and SDIO communication interfaces
Enhances NFC e-paper utility with multi-size support
The Waveshare ST25R3911B NFC Evaluation Kit, NFC Reader, TF Card, USB Cable is an advanced tool designed for NFC-related learning and development, particularly suitable for refreshing passive NFC-powered e-papers. This kit features the ST25R3911B NFC chip, known for its robust performance in NFC applications, and is complemented by the AT32F413RBT7 controller, which operates on an ARM® 32-bit Cortex™-M4F core. The kit includes a 1.3-inch OLED display, user buttons, and various communication interfaces, making it versatile for a range of applications.
The evaluation kit supports multiple NFC protocols, including ISO18092, ISO14443A, ISO14443B, and FeliCa™, as well as customized protocols like MIFARE™ Classic. It is capable of supporting NFC-powered e-papers of various sizes, enhancing its utility in electronic paper applications. The inclusion of a USB to UART converter facilitates debugging, while the micro SD slot and USB cable provide additional connectivity options.
This comprehensive kit is ideal for developers and learners aiming to explore NFC technology and its applications in e-paper and other fields. It offers a practical platform for experimenting with NFC communication and developing innovative solutions.

If you are not satisfied with a product purchased from the Site, you may request a return within 30 days from the delivery date, unless the product is listed under the Return Exceptions below or is subject to specific return conditions noted on the product page.
This return policy also applies, as a minimum standard, to products sold and fulfilled by third-party vendors through the Marketplace.

Return Conditions
To qualify for a refund under the 30-day return policy, all of the following conditions must be met:
A valid Return Authorization (RA) number must be obtained prior to returning the product. Returns without an RA number will be refused.
The RA number is valid for 30 days. The returned item must be received within that period.
The RA number must be included with the return.
Products must be returned in unused, unmodified condition (e.g., no scratches, alterations, missing parts, or signs of installation/use) and in their original packaging, suitable for resale.
Shipping fees are non-refundable. Return shipping costs are the responsibility of the customer, except in cases of a product confirmed defective through RobotShop's troubleshooting process or of a verified shipping error by RobotShop.
Refunds are processed within 7 days after receipt and inspection of the returned item.
A €100 cleaning fee may apply to domestic robots returned in used or unclean condition.
A 20% restocking fee may apply to large-quantity returns of items ordered specifically for the customer from the manufacturer or not part of RobotShop's standard inventory.
Return Exceptions
The following products are not eligible for return or refund under this policy:
Used, damaged, or modified products — Items that show signs of use, wear, or alteration, making them unsuitable for resale.
Consumables * — Use and wear-and-tear components, altered or depleted through use (e.g., batteries, belts, brushes, gears, filament, tires, disposable bags, lubricants, greases, waxes, etc.). Not eligible for return once opened or used.
Perishables — Goods liable to deteriorate or expire rapidly. Not eligible for return.
Sealed goods (health or hygiene) — Items sealed for health-protection or hygiene reasons (e.g., masks, gloves, odor-absorbing products). Not eligible for return once unsealed.
Build-it-yourself products and items requiring customer assembly * — Including robots & kits, robot parts, and other products requiring assembly or soldering. Not eligible for return once assembled, soldered, or installed.
Digital Goods, Software, and Apps * — Final sale only, due to licensing restrictions.
Clearance Items * — Products identified as clearance or final sale, including end-of-life or discontinued items.
Custom-made, personalized, or special-order items — Products manufactured, configured, adapted, or built to the customer's own specifications and requirements.
On-Demand Items * — Standard catalogue products not stocked by RobotShop and ordered specifically to fulfill a customer request.
* European consumers retain their statutory Right of Withdrawal on these items. Its exercise is subject to the conditions and exclusions set out in the Statutory Right of Withdrawal, and any reimbursement may be reduced to reflect a loss in value resulting from handling beyond inspection.
How to Request a Return Authorization (RA)
While the same return policy applies, these orders require a separate contact process for returns.
