SparkFun MicroMod LoRa Function Board

The SparkFun MicroMod LoRa Function Board provides LoRA and LoRaWAN capabilities to your MicroMod project. It is intended to be used in conjunction with a MicroMod Processor Board and a MicroMod Main Board, which provides the electrical interface between a processor board and the Function Board(s).

The LoRa Function Board utilizes the 915M30S LoRa module from EBYTE, which is a 1W (30dBm) transceiver based around the SX1276 from Semtech. There is a robust edge mount RP-SMA connector for large LoRa (915MHz) antennas; with modification, a U.FL connector is also available. We've successfully tested a 12 miles line-of-sight transmission with this module (test was performed under ideal conditions; individual user results may vary).

With the MicroMod standardization, users no longer need to cross-reference schematics with datasheets, while fumbling around with jumper wires. Simply, match up the function board's M.2 edge connector to the slot of the M.2 connector on the main board and secure the function board with screws.

Note: A MicroMod Processor, Main Board, and antenna are not included with this MicroMod LoRa Function Board. These parts will need to be purchased separately.


MicroMod is a modular interface ecosystem that connects a microcontroller “processor board” to various “carrier board” peripherals. Utilizing the M.2 standard, the MicroMod standard is designed to easily swap out processors on the fly. Pair a specialized carrier board for the project you need with your choice of compatible processor!

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.

3 Programming

Skill Level: Competent - The toolchain for programming is a bit more complex and will examples may not be explicitly provided for you. You will be required to have a fundamental knowledge of programming and be required to provide your own code. You may need to modify existing libraries or code to work with your specific hardware. Sensor and hardware interfaces will be SPI or I2C.

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.
