Important: As of 4/23/2021 we are temporarily halting pre-orders of this product due to supply chain concerns.


We expect to fulfill pre-orders placed after 3/30/2021 in September. Pre-orders will be fulfilled in the order they were received.

Earn HNT cryptocurrency by mining and building coverage for The People’s Network using Nebra HNT Hotspot Miner. Anyone can join The People's Network and provide hundreds of square miles of wireless network coverage, while mining HNT on the Helium Blockchain just as Helium Hotspots do.

The People's Network runs on Helium LongFi™, a technology architecture that combines a leading wireless technology, LoRaWAN, and the Helium Blockchain. LongFi™ is optimized for miles of range, and long battery life for IoT devices.

The Nebra HNT Indoor Hotspot Miner earns the cryptocurrency HNT when devices connect., and for validating wireless coverage delivered by peers. Using a system called Proof-of-Coverage, Hotspot Miners earn more HNT when they're in range of other miners, but need to be at least 300 metres apart.

The Hotspot Miner sets up in minutes and has a smartphone app interface. This variation is the outdoor model and comes in an IP-67 rated enclosure. The Nebra Indoor HNT Hotspot Miner provides the same functionality in a more cost-effective enclosure.

Nebra Outdoor HNT Hotspot Miner (915MHz) Product Help and Resources

Core Skill: DIY

Whether it's for assembling a kit, hacking an enclosure, or creating your own parts; the DIY skill is all about knowing how to use tools and the techniques associated with them.


Skill Level: Rookie - Basic hand tools are required and instructions will allow more freedom. You may need to make your own decisions on design. If sewing is required, it will be free-form.
See all skill levels

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.

3 Electrical Prototyping

Skill Level: Competent - You will be required to reference a datasheet or schematic to know how to use a component. Your knowledge of a datasheet will only require basic features like power requirements, pinouts, or communications type. Also, you may need a power supply that?s greater than 12V or more than 1A worth of current.

  • No manual in box, no manual here, none on Nebra's website - except for a crowdsourced doc that doesn't cover the items shipped with the unit. Which antenna goes where? Why are there two, when all of the paperwork insists there's only one? Sparkfun is always so great with help. This unit is not working out like that. Any help would be appreciated.

    • Yeah this was a pain! After opening the unit I confirmed that the top antenna is the longer (30cm) LoRa antenna, and the bottom one is the shorter WiFi antenna. It also needs to be powered from 48V PoE (I used a UniFi device). Finally the unit will appear to do absolutely nothing until you set up port forwarding for incoming TCP port 44158 to its local IP address. Leave it powered and mounted vertically and after a day you'll see some signs of life and mining will begin within 48 hours.
