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.
