Description
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. It is flexible for the users to set the UART baud rate, frequency, output power, data rate, frequency deviation, receiving bandwidth etc parameters. It is your ideal choice for designing wireless data transmission products which can be widely used on wireless data transmission field.

The single module can not work, please get two or more of these modules.
- Wireless communication frequency band is 434M
- Multiple types of serial port transparent transmission modes have respective features, and the mode is changed by command
- User needn’t program the modules, and four modes are only responsible for receiving and sending serial port data, and are convenient to use
- Low current consumption; the idle current is 80?A, 3.5mA or 22mA, depending on the selected mode
- The number of bytes sent to serial port of module unlimited to one time
- All functions and parameters are changed by command, and can be saved in case of power failure
Specification
- Supply voltage 3.2V ~ 5.5V. (If you want to work in the module launch state for a long time, it is recommended when the supply voltage exceeds 4.5V series with a 1N4007 diode, to avoid heating module built LDO)
- Default communication distance (open test): about 600m (adjustable to achieve the maximum communication distance of 1000m, the air baud rate 5000bps).
- The default idle current: 16MA (modules in different operating current of the different operating modes).
- Module Size: 27.8mm × 14.4mm × 4mm.
- Operating frequency range (433.4-473.0MHz, up to 100 communication channels) Maximum 100mW transmit power (can be set)
- The module supports software upgrades. (We provide customers with software upgrades)
- The default factory settings: operating mode FU3, baud rate 9600bps, communication channel CH001 (433.4M).
PS: HC-11 can not be connected to communicate with the HC-12, they work independently, in pairs.
