Frequently Asked Questions
Q1: What is the maximum data rate supported by the CC1101 module?
A: The [E07-M1101D-SMA](https://ebyteiot.com/products/ebyte-e07-m1101d-sma-cc1101-wireless-transceiver-module-low-power) supports a highly flexible air data rate ranging from 0.6kbps to 500kbps, allowing you to optimize for either extreme range or high-speed transmission.
Q2: Can I use this module with a 5V Arduino or MCU?
A: While the [CC1101](https://ebyteiot.com/products/ebyte-e07-m1101d-sma-cc1101-wireless-transceiver-module-low-power) chip is robust, the recommended supply voltage and logic level are strictly 1.8V to 3.6V. If using a 5V MCU, you must use a level shifter or a voltage divider on the SPI lines to prevent damaging the module.
Q3: How do I achieve the maximum 1000m communication distance?
A: To reach the 1km distance, the module should be configured to the lowest air data rate (0.6kbps) and maximum power (10dBm), used in an open area with a 5dBi gain antenna mounted at least 2 meters above ground.
Q4: What antenna connector is pre-installed on the E07-M1101D-SMA?
A: This module features an SMA-K antenna interface, which is a standard female connector suitable for various 433MHz rubber duck or high-gain antennas with an impedance of 50Ω.
