The RF section is based on the TI CC1101 transceiver. Built-in dual single-pole triple-throw (SP3T) RF switches and multi-band RF matching circuits multiplex the 315MHz, 433MHz, 868MHz/915MHz bands to one RP-SMA antenna interface, supporting 2-FSK, 4-FSK, GFSK, MSK, ASK, OOK, and other modulation schemes. The NFC section uses the ST25R3916 chip and supports ISO14443A/B, FeliCa, and ISO15693 protocols. It can operate in reader/writer and card emulation modes. The module communicates via SPI, includes an onboard DC-DC buck circuit, and provides a standard HY2.0-4P Grove interface for easy sensor expansion. It is suitable for wireless remote control, access-control identification, device communication, and IoT prototyping. Compatible Cardputer not included
