M5Stack Cap CC1101 Module
M5Stack Cap CC1101 Module is a wireless expansion module integrating Sub-1 GHz RF and NFC functions, compatible with Cardputer-Adv and CardputerZero. This module offers built-in dual Single-Pole Triple-Throw (SP3T) RF switches and a multi-band RF matching network for dynamic band switching. The Cap CC1101 module supports modulation schemes that include 2-FSK, 4-FSK, GFSK, MSK, ASK, and OOK. This module features an NFC section that uses the ST25R3916 chip and supports ISO14443A/B, FeliCa™, and ISO15693 protocols. The Cap CC1101 module communicates via SPI, includes an onboard DC-DC buck circuit, and provides a standard HY2.0-4P Grove interface for easy sensor expansion. Typical applications include wireless remote control, access-control identification, device communication, and IoT prototyping.
