SeeedStudio - 434Mhz Wireless Serial Transceiver Module - 40 Meters - DIY Maker Open Source BOOOLE

The single module can not work, please get two or more of these modules. And please note that this module do not work with the 433Mhz Wireless Serial Transmitter Module - 1 Kilometer.

Features:

- Wireless communication frequency band is 434M
- Multiple types of serial port transparent transmission modes have respective features, and the mode is changed by command

Serial transceiver module is a low cost, high performance transparent FSK transceiver with operating at 434 MHz. It features small size, high output power, high sensitivity, long transmission distance and high communication data rate with auto set up for communication change and data receiving and transmission control. There is UART interface, it is easy to realize the wireless data transmission with only providing the UART data.
