WT 801


WT 801 is a new generation of multi-channel embedded RF transceiver module. It has multiple 1 kHz steps, the maximum RF power is 100 mW, and the size is small (34.5mm × 20 mm × 6.0mm). The module has low power consumption and is suitable for battery power systems.



WT 801 is a highly integrated low-power half-duplex RF transceiver module, which is embedded in a high-speed low-power microcontroller and a high-performance RF chip. Compared with the existing RF transceivers based on FSK or OOK modulation, it has more advantages. long distance. The WT801 module provides multiple options, and users can modify parameters such as serial port rate, transmission power, and radio frequency online.

The module uses a Lora modem, and the sensitivity is increased to -137 dBm, which greatly extends the transmission distance under low power consumption. Therefore, repeaters and complex communication infrastructure are not required. Due to the increased transmission distance, users can greatly reduce the use of repeaters, simplify system design, and reduce production costs.

The WT 801 module supplies 2.6-3.6V and consumes only 13 mA in receive mode. The WT 801 module has four working modes, and each module can be switched freely. In power saving mode, the module consumes only 1.3uA. The 3.6V/3.6AH lithium battery can work for several years and is very suitable for battery-powered systems.
