Description

Radio transmitter/receiver operating in theLoRa standard powered with the rechargeableli-pol batteryor via USB, it is running at frequencies of868/915 MHz. The heart of the module is an 8-bitATmega32u4microcontroller  with a clock frequency of8 MHz, it has the 32 kb of flash memoryand2 KB of RAM. It is ideal forIoTprojects(Internet of Things)or those that require mobility due to the possibility of a powering with theli-polrechargeablebatteryand its powering. In case of detection of a USB power, the module automatically switches the power source and begins to charge the battery.

Integrated radio module based onSX1276 Lora system and yields about2 km rangewhen using a simple antenna in the form of a simple cable soldered to ANT pins.The product is fully compatible withArduinoavailable is also theLoRalibrary with the set of all instructions to create the connections.The manufacturer also provides examples of source codes on the website.
