Description Module CC1101 is a high-performance 855-925MHz wireless communication module for M5Stack Core series expansion. It uses the E07-900M10S module solution with a built-in CC1101 low-power Sub-1 GHz RF transceiver, providing stable wireless data transmission with efficient power consumption. Module CC1101 communicates through SPI and supports 2-FSK, 4-FSK, GFSK, MSK, ASK and OOK modulation modes. Its CC1101 RF transceiver includes independent 64-byte RX FIFO and TX FIFO buffers, RSSI, LQI and up to -109 dBm receive sensitivity at a 1.2kbps rate. Module CC1101 provides an external SMA antenna interface, an included 2.5dBi rubber antenna and onboard DIP switches for flexible pin selection on the M5-Bus. The DIP switch design lets Module CC1101 adapt to different controller devices and helps multiple stacked modules share the bus for wireless control, smart home and automation projects. Features Sub-1 GHz wireless module: Module CC1101 uses the E07-900M10S module based on the CC1101 low-power RF transceiver. 855-925MHz operating range: Module CC1101 supports wireless communication across the 855-925MHz band. SPI interface: the module connects through SPI for controller integration and stacked M5Stack Core expansion. Multiple modulation modes: supports 2-FSK, 4-FSK, GFSK, MSK, ASK and OOK for flexible wireless data links. Signal quality data: Module CC1101 supports RSSI and LQI for received signal and link quality evaluation. FIFO buffering: independent 64-byte RX FIFO and TX FIFO help manage RF data transfer. Low power operation: sleep current is specified at DC 5V @ 26.48uA, with standby current at DC 5V @ 1.74mA. DIP switch pin selection: onboard DIP switches help adapt Module CC1101 to different Core devices and expansion layouts. External antenna: the SMA antenna interface and included rubber antenna support longer-range wireless experiments. Development support: Arduino quick start, RadioLib library and UiFlow2 documentation are available for Module CC1101.

Product List 1 x Module CC1101 1 x SMA rubber antenna Other Content M5-Bus DIP Switch The SW-marked pins on the lower M5-Bus can be switched through the DIP switches so Module CC1101 can adapt to different controller devices. GD00 and GD02 share the same three selectable IO options, so choose different pins to avoid functional conflicts. M5-Bus PinMap Highlights SPI MOSI, MISO and SCK are fixed on the M5-Bus, while CSN is switch-selectable. Interrupt Pins GD00 and GD02 are switch-selectable M5-Bus pins and should not use the same selected IO at the same time. Power Pins Module CC1101 uses 5V and HPWR pins on the M5-Bus. Stacking The DIP switch layout supports stacked module use when pin conflicts are avoided.
