Waveshare ST25R3911B NFC Evaluation Kit NFC Reader Ideal for Refreshing Passive NFC-Powered E-Papers
Description
Overview This is an NFC development kit based on ST25R3911B, with AT32F413RBT7 controller, OLED display, user buttons, and common used 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 low-power capacitive wakeup function. It suits applications which require high RF performance, flexibility, and low power consumption, such as access control, ticketing, industry, medical treatment, consumption product, and so on. Features Multi protocols support: ISO18092, ISO14443A, ISO14443B , ISO15693, FeliCaDifferential antenna design, output power up to 1.4W, longer sensing distanceEmbedded low-power capacitive sensor, allows sensing and capacitive wakeup, detecting the nearby card without enabling the magnetic field of the readerAT32F413RBT7 controller, easy for learning, evaluating, or direct integration, needs no other external controller1.3" OLED display, allows visual operationOnboard SRAM, additional space to the inner RAMMicro SD slot, supports external TF card for storing data to be transferred via NFC4x buttons, 2x user indicators, convenient for debuggingOnboard programming interface, UART debugging interface, breakout all the unused IO pins for connecting other user peripheralsCustomized acrylic case, protective and dust-proof, better lookingComes with development resources and manual What's on Board AT32F413RBT7Core: ARM 32-bit Cortex-M4F Operating Frequency: 200MHz Operating Voltage: 2.0V-3.6V Package: LQFP64 Memories: 128kB Flash, 32kB SRAM Communication Interfaces: 2 x SPI, 5 x USART, 2 x I2C, 2 x CAN, 1 x USB, 1x SDIO AD & DA Converters: 2 x AD (12-bit, shares 16 channels) ST25R3911B: NFC chip, aka AS3911B23LC1024: SRAM, 1MbitCP2102: USB TO UART converter, for debuggingSPX3819: 3.3V voltage regulator1.3" OLED: blue display, 128×64 pixels, SH1106 driver4x user buttons:2x user indicatorsMCU unused pinsUSB TO UART portMicro SD slotSWD programming interfaceNFC induction coilUART pin configuration RXD: connected to RXD2 by default, changeable to RXD1 via 0Ω resistor TXD: connected to TXD2 by default, changeable to TXD1 via 0Ω resistor Dimension Wiki
