SUB-1 GHz + NFC CAP
Wireless exploration and NFC workflows in one Cardputer expansion.
The Cap CC1101 & NFC for Cardputer Zero / Adv combines a TI CC1101 multi-band transceiver with an ST25R3916 NFC front end. It connects over SPI and fits the Cardputer expansion slot for compact RF testing, access-control identification, device communication and IoT prototyping.
CC1101 Sub-1 GHz radio
Dual SP3T RF switches and a multi-band matching network route 315, 433, 868 and 915 MHz operation through one RP-SMA antenna connector. The CC1101 supports 2-FSK, 4-FSK, GFSK, MSK, ASK and OOK modulation, with independent 64-byte receive and transmit FIFOs.
- 315 / 433 / 868 / 915 MHz operating bands
- Up to +10 dBm transmit power and -99.5 dBm receive sensitivity
- RP-SMA female antenna connector
- Three matched rubber antennas included
ST25R3916 NFC reader and emulator
The integrated NFC front end supports common contactless card and tag standards for reader/writer projects, diagnostics and authorized emulation experiments.
- NFC-A and NFC-B, compatible with ISO14443A/B
- NFC-F / FeliCa
- NFC-V / ISO15693
- Reader/writer mode plus NFC-A and NFC-F card emulation
- 512-byte NFC FIFO
Designed for Cardputer Zero and Adv
The module is compatible with Cardputer Zero and Cardputer Adv. An onboard DC-DC buck circuit supports stable operation, while the HY2.0-4P Grove port leaves room for sensor expansion. Development is supported with Arduino and UIFlow2.
Typical applications
- Wireless remote-control experimentation
- NFC and access-control identification
- Sub-1 GHz device communication
- Portable IoT and sensor prototypes
