What is XRange?
It is a wireless
electronics development platform that provides extreme long range
spread spectrum communication and has over 12km (7 miles) of usable range.
XRange
is based on the SX1272 LoRa™ long range modem, low-power ARM
micro-controller and powerful switching power supply.
According to Semtech's Presentation
What can you do with XRange?
- Connections in warehouses where data cables and other wiring is difficult or impractical.
- Lighting, temperature and other building controls.
- Battery-powered data loggers, weather stations, and data logger/controllers.
- Solar panels management and monitoring.
- Data communication for the Internet of Things.
- Remote controlled irrigation systems.
- Point-of-sale systems.
- Security applications.
Why You should choose the XRange?
- It has extreme long
range.
- It has ability to
communicated through walls and other obstructions.
- It is low power.
- It is low cost.
- You can implement
many wireless projects with little effort.

Description
Battery Base Board
This board is lithium polymer battery charger (Li-Po battery is not included). When connected
to the XRange, the Battery Base Board can act as a power source to the XRange and provide portability and flexibility on applications.
Range Test
Software
development
We are working to provide open source libraries and
firmware.
Mbed
“The mbed
development platform is the fastest way to create products based on
ARM microcontrollers.”
We are working to
provide libraries and firmware based on Mbed platform.
Keil MDK
We have developed libraries and firmware based on Keil MDK platform.
Project Plan
Some components, especially if ordered in bulk, can have lead times
up to 12 weeks, so we might need to revise our timeline if we
get a very high number of orders.
XRange
needs your help!
We will use the funds from the campaign to develop the final
hardware and the software for Mbed support. We
need support to run mass production that will lower the cost of XRange.
There are six PCB prototyping boars based on SX1272RF1BAS
You can use them to build your SX1272RF1BAS modules.
