Product Description: NFC Development Kit - STM32 ST25R3911B - Waveshare 17623
NFC development kit based on STM32 ST25R3911B microcontroller with AT32F413RCT7 driver and OLED display , programmable buttons and popular interfaces . Perfect for learning about NFC communication and creating projects based on this method of communication. It supports multiple NFC protocols with a maximum output power of up to 1.4W and a low current capacitive wake function. It will work in applications requiring high RF performance and low power consumption, such as access control, ticketing, industry, medical industry, etc.
Main features of the NFC development kit
- Multiple protocol support: ISO18092, ISO14443A, ISO14443B, ISO15693, FeliCa.
- Differential antenna design, output power up to 1.4W, longer sensing distance.
- The built-in low-power capacitive sensor allows capacitive wake-up, detects nearby cards without activating the reader's magnetic field.
