Wireless LoRa Module With SX1278 Chip and UART Transparent Transmission

Wireless LoRa Module with SX1278 Chip and UART Transparent Transmission

DL-RTS1278M is a high-performance wireless serial port LoRa module developed by DreamLnk for wireless meter reading and industrial remote control, it was embedded with high-speed low-power MCU and high-performance spread-spectrum RF chip SX1278, with LoRa spread-spectrum technology, while using efficient cyclic interleaving error correction coding, anti-interference and sensitivity are at the most advanced level in the industry. 

This LoRa Module provides multiple channel selections, and can online modify the serial port rate, transceiver frequency, transmit power, RF rate and other parameters. The default frequency is 434.125MHz. The working voltage of this RF module is 2.1-3.6V, and only consumes 13mA in the receiving state. 

DL-RTS1278M has four working modes, which can be arbitrarily switched between the modes. In the 1SEC cycle polling wake-up power saving mode (Polling mode), the reception consumes only tens of microamps, a section of lithium at 3.6V / 3.6AH. The sub-battery can work for several years and is very suitable for battery-powered systems.
