It is part of the Modtronix iMod product range. The SX1276 is a revolutionary new chip enabling wireless communications at distances up to 15km, using Semtech's LoRa(Long Range) technology. This chip also supports high performance (G)FSK modes for systems including WMBus, IEEE802.15.4g. The board is a high quality, RF optimized, 4 layer PCB. It has been designed with assistance from Semtech engineers, ensuring optimum layout and performance! Only brand name, high quality components are used! All capacitors and inductors are high precision parts, resulting in optimized performance. The crystal a very critical component for the SX1276, and is required to be very accurate to achieve high sensitivity. This board uses a high accuracy crystal as recommended by Semtech. This module will outperform competitor products that use 2 layer PCBs, cheap capacitors and inductors and low accuracy crystals! When choosing a SX1276 module, it is very important to realize that they will NOT all perform the same just because they use the same chip! Designing RF boards is very tricky, and lots of power and sensitivity is lost due to bad PCB design and poor components! This module enables 3.3V devices (like a Microcontroller for example) to communicate with remote nodes via a wireless protocol.For details on the SX1276 chip, download it's datasheet from www.semtech.com. A 868MHz version of this board, the inAir8, will be available early 2015. A SMA Edge connector (Modtronix part CON-SMA-FE16-RG) is mounted on this board. It can however also be assembled with a U.FL (Modtronix part CON-UFL) connector. Two standard 1x7, 2.54mm (0.1") pin headers can be soldered onto this board (position X1 and X2 on board). On request, we can include free pin headers with this board. If required, wires can of course be soldered onto the PCB in stead of pin headers. If required, this module can also be used as a SX1276 breakout board, and wires can be soldered onto the PCB in stead of pin headers.

Module dimension: 27.3mm x 24.51mm (1.075" x 0.965") RoHS Compliant Operating Temperature -40°C to + 85°C Documentation Web PDF Data inAir9 Datasheet and Schematics Expansion & Software The inAir9 module can be used with virtually any Microcontroller that has a SPI port, some free I/Os, and operates at 1.8-3.3V. STM32 Microcontrollers Click to Enlarge We are currently busy with a STM32 Microcontroller board that will accept the inAir9 module as a daughter board. For a prevue, see Modtronix forum. The first of these boards will be assembled with the STM32L151RC microcontroller (compatible with other STM32L151 and STM32L152 chips). The board will have a Lithium Polymer battery charger, 3.3V DC/DC regulator, high speed and RTC crystal, LEDs, buttons and circuitry for doing various analog measurements. It will be followed by alternative versions assembled with the STM32F030R8T6 (low cost), STM32F205RCT6 and STM32F411RCT6 microcontrollers. It can also be assembled with custom STM32F0, STM32F1, STM32F2, STM32F3, STM32F4 (STM32F401 for example) chips on request. mbed Platform A SX1276 API, and various example projects are available on the mbed.org developer site (search site for SX1276). We will also be providing an example project for our STM32 board mentioned above, and the inAir9. Other Semtech recently announced that Microchip Technology Inc. adopted Semtech’s long-range LoRa™ RF technology. We still have to perform tests, but it is possible that these modules will be compatible with Microchip's example code. Special versions of this board using Microchip LoRa chips can also be assembled on request (once these chips become available). What is included 1 x Module, with SMA connector assembled. Orders will be shipped within 1-2 business days from receiving payment. In most cases (close to 100%), orders received before 2pm will be shipped the same day.
