About this item

  • What Is LoRa?: LoRa (Long Range) is a low-power wireless protocol for communicating over several kilometers. This LoRa module uses the SX1276 transceiver for robust, long-distance communication, ideal for IoT and remote sensor projects.
  • Prototyping Made Easy: This all-in-one LoRa Module Prototyping Kit helps you build and test LoRa-based projects quickly. Perfect for beginners or experienced developers working on low-power, long-range wireless applications.
  • Compatible & Versatile: This LoRa Module Prototyping kit works with any 5V or 3.3V microcontroller development boards. If using a 3.3V microcontroller such as the ESP32 microWatt, then you can simply connect the logic pins directly. If using a 5V microcontroller such as the Nano Flip or the Uno R3+, then you must use the included logic-level shifter (LLS) before connecting to the pins of the LoRa Module. Please see the datasheet and tutorials for more information.
  • What’s Included: Each package includes two (2) LoRa Module 915MHz SX1276 transceivers with antenna, two (2) PTSolns LoRa Keys, two (2) logic level shifters, two (2) voltage regulators, four (4) capacitors, all required header pins. This is a kit, SOLDERING REQUIRED.
  • PTSolns Customer Support & Resources: We’re here to help. Contact PTSolns support for assistance or technical questions. Every PTSolns product is backed by our comprehensive resource library, including datasheets, schematics, 3D models, Fritzing files, and tutorials.

    Product Description

    PTSolns LoRa Key 915MHz SX1276 LoRa transceiver breakout board with 2.54mm pitch adapter, 8-channel bi-directional logic level shifter for 3.3V and 5V compatibility, integrated LM1117 3.3V voltage regulator and smoothing capacitors, designed for easy prototyping of long-range RF communication nodes in North America
    The PTSolns LoRa Key allows for quick and efficient prototyping with the 915MHz LoRa Module. The LoRa Module has a non-standard pitch and does not interface with common breadboards. The Key acts as a pitch adapter and allows the LoRa Module to work with a standard breadboard. Furthermore, the LoRa Key is very skinny and frees up more space on the breadboard.

    This LoRa Module prototyping kit allows the user to get started in the world of LoRa very quickly. The package includes enough parts to make to wireless LoRa nodes. Tutorials are provided for getting started quickly.

    For datasheet and other supporting material please see our "PTSolns Documentation Repository".

     

    More Details

    This LoRa module 915MHz SX1276 transceiver is a popular communication module used for long range communication. Working with RF can be difficult, especially when first starting out in the field. The LoRa in particular can be cumbersome to get working. Hence we created this complete package to get users working/prototyping with the LoRa quickly and with ease. This package includes the hardware required to make two LoRa transceiver nodes. Note that microcontrollers are not included as the LoRa can be interfaced to work with a large range of microcontrollers.

    This package includes the following highlights:
    • LoRa transceiver. In North America the free band that hobbyists can use is in the 915MHz range. This LoRa package is intended for this use. Warning: Other LoRa distributors may sell a transceiver set to a frequency that is not allowed to be used in North America (such as the 169MHZ, 315MHz, 433MHz, 868MHz versions of the LoRa transceiver).
    • PTSolns LoRa Key. The LoRa has a pinout pitch of 2.0mm, which is not common and will not interface with a standard breadboard. The LoRa Key is a breakout board and adapter that lets the user interface the LoRa with standard pitch of 2.54mm (0.1in) boards.
    • 8-Channel bi-directional logic level shifter (LLS). The LoRa works on 3.3V logic. If connecting the LoRa to a 5V microcontroller such as the Nano or Uno a LLS must be used to convert the 5V logic signals to 3.3V logic signals. 
    • Voltage regulator and capacitor: The LoRa module can be powered externally with the use of the LM1117 3.3V voltage regulator and the 10μF smoothing capacitors.

      A Complete Package for Two LoRa Nodes

      Product contents image showing all separate parts included in the PTSolns LoRa Key package: two LoRa SX1276 915MHz transceiver modules, two PTSolns LoRa Key breakout boards with 2.54mm pitch adapters, 8-channel bi-directional logic level shifters, LM1117 3.3V voltage regulators, smoothing capacitors, and assembly instructions—required assembly for full prototyping setup
      This package includes all the hardware to make two LoRa nodes (not including the microcontroller development boards).

      If you are working with a 5V microcontroller such as the Nano Flip or Uno R3+, then you will need to shift the logic levels down to 3.3V. This package already includes the required logic level shifters (LLS).

      If you are working with a 3.3V microcontroller such as the ESP32 microWatt, then you do not need to shift the logic levels and can connect directly to the LoRa Module pins.

      Hardware Setup Example Using 3.3V Microcontroller

      Example hardware setup image showing the PTSolns LoRa Key connected to a common 3.3V Pro Mini microcontroller board, demonstrating the simplest configuration without the use of logic level shifters or external voltage regulators for basic LoRa communication prototyping.

      Please see our free tutorial available here.

      Example shows hardware setup using the common 3.3V Pro Mini microcontroller. This is the simplest possible setup in which the logic level shifter and external voltage regulators are not used.

      NOTE 1: If using a 5V microcontroller such as the Nano, Uno, etc. then the logic level shifter (included in this package) must be placed between the signals of the microcontroller and the LoRa module transceiver.

      NOTE 2: Breadboard, Dupont wires, and FTDI USB to TTL serial converter module not included. Shown here for demonstration purposes.

      Technical Capabilities of the LoRa Key

      Technical image of PTSolns LoRa Key showing breakout pins for LoRa module with 2.0mm pitch adapter to common 2.54mm (0.1 inch) pitch, solder points for external antenna on both LoRa Key PCB and LoRa module, silkscreen printing on top and bottom PCB layers, long soldering pads and through-holes for direct soldering or header connections, and Canadian-designed branding

       The PTSolns LoRa Key has the following unique technical capabilities:

      • Breakout LoRa pins and adapter 2.0mm pitch to the common 2.54mm/0.1in pitch.
      • External antenna can be solder directly onto the LoRa Key PCB, or the LoRa module itself.
      • Silkscreen printing on both sides of the PCB.
      • Long soldering pads and through-holes allow the LoRa modules to be soldered directly onto the PCB, or connected to the PCB via the included male and female 2.0mm headers (recommended).
      • Canadian designed!

      Exceptional quality; designed with intent

      This set is exceptionally well designed and its quality shows. I verified that the signal power was more than sufficient for 6 km of range when the devices had mutually clear line of sight.
      The soldering pads are big and easily accessible, which is great for me since I'm not that great with a soldering gun.
      The packaging is very professional. I liked that the tx/rx chips were sectioned off from the other parts so that it's easier to make sense of when you pull it all out of the bag. This is like Lego for super nerds so these finer details matter.
      As a sidenote I've also worked with their customer support and they were very helpful which is a big plus because I'm kind of a noob. Overall would highly recommend this brand.
