Features

• 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 wakeup, detecting the nearby card without enabling the magnetic field of the reader
• STM32F103RBT6 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
• 4x buttons, 2x 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 manual
