Cap CC1101
SKU:U219
Description
Cap CC1101 is an expansion module integrating Sub-1 GHz RF and NFC functionality. The RF section is based on the TI CC1101 transceiver. Through built-in single-pole triple-throw (SP3T) RF switches and multi-band RF matching circuits, it converges the four frequency bands of 315MHz, 433MHz, 868MHz, and 915MHz to a single RP-SMA antenna port, supporting modulation schemes such as 2-FSK, 4-FSK, GFSK, MSK, ASK, and OOK.
The NFC section adopts the ST25R3916 chip, supporting ISO14443A/B, FeliCa™, and ISO15693 protocols. It can operate in reader/writer or card emulation mode, with a maximum reading distance of up to 45mm. The module communicates via SPI, features an onboard DC-DC buck circuit, and provides a standard Grove interface for easy sensor expansion. It is suitable for scenarios such as remote control signal capturing and replaying, reading and emulating access cards/transit cards, and smart home DIY.
