Description

LoRaST 433MHz /470MHz /868MHz /915MHz Open Source Long Range Wireless LoRa Transceiver is a small wireless transceiver module offers a very compelling mix of long range, low power consumption and secure data transmission..It is designed to facilitate developers to quickly deploy industrial level LoRa and IoT solutions. It help users to turn the idea into a practical application and make the Internet of Things a reality. It is easy to program, create and connect your things everywhere. 

LoRaST wireless part is based on SX1276/SX1278 which allows the user to send data and reach extremely long ranges at low data-rates.It provides ultra-long range spread spectrum communication and high interference immunity whilst minimising current consumption.It targets professional wireless sensor network applications such as irrigation systems, smart metering, smart cities, smartphone detection, building automation, and so on.

LoRaST mcu part use STM32l0x chip from ST, STML0x is the ultra-low-power STM32L072xx microcontrollers incorporate the connectivity power of the universal serial bus (USB 2.0 crystal-less) with the high-performance ARM® Cortex®-M0+ 32-bit RISC core operating at a 32 MHz frequency, a memory protection unit (MPU), high-speed embedded memories (192 Kbytes of Flash program memory, 6 Kbytes of data EEPa0 Kbytes of RAM) plus an extensive range of enhanced I/Os and peripherals via industrial standard M.2 (NGFF) pin interface.

LoRaST is an open source product, it is based on the STM32Cube HAL drivers, with customer application examples, user can program LoRaST via USART1 , USART2 or STLINK. The factory firmware supports LoRaWAN 1.0.2 specification and user can use AT Command to set up it and use for their project directly. User can re-compile the firmware to support different LoRaWAN Frequency, includes: EU868, AS925, AU915, CN470, CN779, EU433, IN865, KR920, US915.
