Introduction
1.1 Introduction
The BL268T-H4 is an industrial UART wireless pass-through module with
high stability. The module uses Semtech SX1280/SX1281 devices with LoRa
spread spectrum transmission and TTL level output. Compared with other 2.4G
communication technologies, LoRa direct sequence spread spectrum
technology has the advantages of low power consumption, longer
communication distance and strong anti-interference ability.
The module supports the PUDU LoRa TSCH standard communication
technology, and can be used as a common transparent LoRa module, and can
also greatly improve the anti-interference performance and bandwidth
utilization under the PUDU LoRa TSCH communication system.
BL268T-H4 has a working frequency range of 2400MHz ~ 2500MHz, and each
channel has an interval of 300KHz. Various parameters such as working mode,
transmitting and receiving frequency, transmitting frequency and RF speed
can be modified online.
