EByte E07-M1101D-SMA CC1101 433MHz FSK RF Module

Connect the module's SPI pins (SI, SO, SCK) and chip select (CSn) to corresponding GPIOs on your microcontroller. Use a 3.3V power supply for VCC and GND. You will need a CC1101 library (like Panstamp's or Electric Imp's) to handle SPI communication, configure the RF parameters like frequency and data rate, and manage packet transmission and reception within your Arduino IDE or PlatformIO sketch.

Use a 433MHz antenna with an SMA male connector. A simple 1/4 wave whip antenna (approx. 17cm) provides good omnidirectional coverage. For longer range, consider a higher gain (e.g., 3dBi or 5dBi) external antenna mounted outdoors. Ensure the antenna is tuned for the 433MHz ISM band to maximize radiation efficiency and achieve the module's specified 0.6km line-of-sight range.

The module draws approximately 29mA during transmission and 18mA while receiving. To conserve battery power, utilize the CC1101 chip's built-in low-power modes (e.g., IDLE, WOR). Send the appropriate SPI command to put the radio into a deep sleep state when not actively communicating. Your host microcontroller should manage the power cycle, waking the module only for scheduled data transmissions to minimize average current draw.

Yes, the Texas Instruments CC1101 chip is highly configurable via its SPI interface. You can adjust the carrier frequency within the 433MHz ISM band, set the data rate from 0.6 kbps to 500 kbps, and modify modulation parameters like frequency deviation. These settings are programmed by writing to the chip's configuration registers using a suitable driver library before initiating communication.
