==Introduction==
This is an NFC development kit based on ST25R3911B, with an AT32F413RBT7 controller, OLED display, user buttons, and common user interfaces. It is your ideal choice for learning and developing NFC applications.

Multiple NFC protocols are supported by the kit, with up to 1.4w output power, and a low-power capacitive wake-up function. It suits applications that require high RF performance, flexibility, and low power consumption, such as access control, ticketing, industry, medical treatment, consumer product, and so on.

===Feature===
*Multi protocols support ISO18092, ISO14443A, ISO14443B , ISO15693, FeliCa™.
*Differential antenna design, output power up to 1.4W, longer sensing distance.
*Embedded low-power capacitive sensor, allows sensing and capacitive wake-up, detecting the nearby card without enabling the magnetic field of the reader.
*AT32F413RBT7 controller, easy for learning, evaluating, or direct integration, needs no other external controller.
*1.3" OLED display, allows visual operation.
*Onboard SRAM, additional space to the inner RAM.
*Micro SD slot, supports external TF card for storing data to be transferred via NFC.
*4 x buttons, 2 x user indicators, convenient for debugging.
*Onboard programming interface, UART debugging interface, breakout all the unused IO pins for connecting other user peripherals.
*Customized acrylic case, protective and dust-proof, better looking.
*Comes with development resources and a manual.
