The Waveshare ST25R3911B NFC Development Kit, NFC Reader, AT32F413RCT7 Controller, Multi NFC Protocols is an advanced tool designed for the development and learning of NFC applications. It integrates the ST25R3911B NFC chip and the AT32F413RCT7 controller, providing robust support for multiple NFC protocols. The kit is equipped with a 1.3-inch OLED display, user buttons, and various interfaces, making it suitable for applications requiring high RF performance, flexibility, and low power consumption.
This development kit is ideal for sectors such as access control, ticketing, industrial applications, medical treatment, and consumer products. It features a differential antenna design that delivers up to 1.4W of output power, ensuring a longer sensing distance. The embedded low-power capacitive sensor allows for capacitive wakeup, detecting nearby cards without activating the reader's magnetic field.
The AT32F413RCT7 controller facilitates easy learning and integration, eliminating the need for additional external controllers. The kit also includes onboard SRAM for additional memory space, a micro SD slot for data storage, and a customized acrylic case for protection and aesthetics. Debugging is made convenient with four user buttons, two user indicators, and an onboard programming interface.
Note: Ensure proper handling to avoid damage to the electronic components.
