SparkFun Pro RF - LoRa, 915MHz (SAMD21)

The SparkFun Pro RF is a LoRa®-enabled wireless board that marries a SAMD21 and a long-range RFM95W to make a compact and easy-to-use IoT Arduino board. With its fast MCU and excellent point to point data transmission in the 915MHz ISM band with LoRa Capabilities, the Pro RF is a great choice for anyone interested or experienced in utilizing long range data communication.

Every pin on the SparkFun Pro RF is accompanied with a ground connection making the buttons and LEDs easy to connect. In case your building something to be embedded into clothing or other physically harsh environment the antenna includes a stress relief hole to make sure your wire antenna survives. A short (3 inch) wire antenna is sufficient for “short” distances (up to 1 mile line-of-sight), but we’ve also included a u.FL antennae connector for potentially longer distances.

The Pro RF also includes a power switch and 2-pin JST connector for powering from a lithium battery. With a Micro-B USB and the power switch in the off position, the Pro RF will charge the attached battery! The board programs over a reinforced Micro-B connector with a slim reset button that fits nicely on the side of the board. We’ve even added our popular Qwiic connector to the edge of the board making it incredibly easy to add sensors and actuators without the need for solder or a soldering iron!

Thanks to the Arduino LoRa library, the RFM95W radio is an easy to use packet radio. But it doesn’t stop there because closing a few jumpers on the underside of the SAMD21 Pro RF initiates LoRaWAN mode on the radio module making it a node in a distributed sensor network.

Core Skill: Programming

If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.

2 Programming

Skill Level: Rookie - You will need a better fundamental understand of what code is, and how it works. You will be using beginner-level software and development tools like Arduino. You will be dealing directly with code, but numerous examples and libraries are available. Sensors or shields will communicate with serial or TTL.

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

2 Electrical Prototyping

Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

  • I am unable to get this to even do blink. Just get compile errors from some fault in the library set-up. I have uninstalled and re-installed over and over. Tried different versions. Get the same thing all night. Please tell me what I am doing wrong:

    fatal error: variant.h: No such file or directory #include “variant.h”

    here is the log:
