915 Generation ST25R3911B NFC Development Board ST25R3911B Reader Onboard

1. Support ISO18092, ISO14443A, ISO14443B, ISO15693, FeliCa™ and other protocols
2. Using differential antenna design, the output power can reach 1.4W, and the sensing distance is .Built-in low-power capacitive sensor, supports induction and capacitive , and can sense the presence of a card without turning on the magnetic field of the card reader.
3. The onboard STM32F103RBT6 controller is convenient for direct learning and evaluation or development and integration, no need to connect other main control boards
4. Onboard 1.3-inch OLED screen, convenient for users to operate visually. Onboard SRAM memory chip, no afraid of insufficient internal RAM. Onboard -SD card slot, external TF card can be used to NFC data to be transmitted.
5. There are four buttons and two indicators on the board, which is convenient for users to debug. Onboard download interface, serial port debugging interface, and lead out the unoccupied IO port, which is convenient for users to connect other devices.
