Lola™ based spread spectrum modulation, with long range 433MHz module low power wt-900m Lola clear module based on Lola™ spread spectrum modulation, a highly integrated low power half-” dual RF transceiver module embedded with high speed low power Microcontrollers with Lola modems and high-performance RF chips can achieve significant timescales compared to existing RF transceivers based on frequency shift keying or book modulation.
Based on LoRa™ spread spectrum modulation, the low power module with long term 433MHz WT-900M is a highly integrated low power half-” dual RF transceiver module embedded with high speed low power MCU with LoRa modem and high performance RF chip It can achieve a significant time range compared to the existing RF transceivers based on frequency shift keying or book modulation. The WT-900M module provides multi-channel options, and users can modify parameters such as serial port rate, transmission power, and radio frequency online.
The module uses a LoRa modem, the sensitivity is increased to -144.1dBm, and the transmission distance is significantly extended at low power consumption. Repeaters and complex communication infrastructure are therefore 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-900M module provides 2.6-3.6 V and consumes only 15ma in receive mode. The WT-900M module has four working modes, each of which can be switched freely. In power saving mode, the module power consumption is only 1.13uA. 3.6 V / 3.6 AH Lithium batteries can last for several years and are ideal for battery powered systems.
