Product Description
The VT-DTM-UART-433 module is designed as a wireless sub module for wireless communication between devices like controls, POS systems, data collectors etc. It offers several addressing modes and relieves the host systems of wireless-specific task such as checksum calculation, address resolution.
It can be deployed whenever the wireless exchange of data packet between two or more parties is required.
A UART interface is available for communicating with the host systems. The data rate is 9.6kbps, data format is 8N1.
Thanks to its small size, the module can easily be installed in existing systems without any external circuits.

Note:
1. Noted that higher radio data rate causes of shorter communication disdance.
2. Noted that higher radio data rate causes of lower sensitivity.
3. Noted that lower input voltage causes of lower output power.
4. Noted that the operate temperature out of range -40℃~85℃ will influence the center frequency.
5. Be sure to use a match antenna and mount it in the right way.
6. The environment will influence the communication disdance much.
