Dragino LT-22222-L LoRa I/O Controller Node

The Dragino LT22222-L Series I/O module with SX1276/78 is a long-range LoRa I/O controller with a pre-programmed STM32 microcontroller. The Dragino module includes various I/O interfaces such as: Analog current input, analog voltage input, relay output, digital input (bidirectional), and digital output etc. The LT I/O module was designed to simplify I/O monitoring and load switching with LoRa. The LT I/O Controller allows the user to send and receive data over a long range thanks to LoRa. The LT I/O Controller aims to enable a simple and cost-effective installation through the use of LoRa radio technology. The controller is already programmed and has a unique EUI ID and can be easily put into operation via TTN Network using OTAA. Detailed information can be found in the user manual.
