The module does not come with a camera module.

The frequency of mmWave radar typically refers to the millimeter wave frequency range used for radar applications. The specific frequency range can vary depending on the system and application, but it generally falls within the range of 30 to 300 gigahertz (GHz), which corresponds to wavelengths of 1 to 10 millimeters.

In automotive radar systems, for example, the frequency range for mmWave radar typically falls between 76 and 81 GHz. This frequency range is chosen for its characteristics, including good resolution, high bandwidth, and the ability to support high-resolution imaging and sensing in various weather conditions.

It's worth noting that different radar systems may operate at different frequencies within the mmWave range, depending on the specific requirements and regulations of the application.

An individual master device Bluetooth module can simultaneously establish connections with multiple slave device Bluetooth modules.

Similar to a radio broadcast (slave) and a radio (master), a radio broadcast can be picked up by multiple radios. Similarly, a Bluetooth slave can send out a Bluetooth broadcast signal within a certain range (usually within a few tens of meters), at which time the surrounding. The Bluetooth host can receive the broadcast information from the Bluetooth slave.

In addition, the Bluetooth host can be connected one-to-one with the Bluetooth slave, and the connection can be encrypted or unencrypted data communication.

One-to-Many can be achieved in a time-division manner, where it appears that one master can control N slaves, but in reality, it rapidly connects, communicates, and disconnects with N slaves in succession.

Many-to-One can be achieved without establishing a connection, where the slave broadcasts and the master receives the broadcast information.

Non-connected mode (unidirectional transmission): The slave broadcasts data, and the master receives it.

Connected mode (bidirectional transmission): The master connects to the slave, and both the master and slave can exchange data with each other.
