The new version of the Nebra Rock Pi V2 hotspot...
The new version of the Nebra Rock Pi V2 hotspot (Reprogrammed chip + functional bluetooth) allows to deploy a coverage point of the Helium network, for connected objects running on the LoRa EU868 ISM band in Europe and in France and at the same time to mine the HNT (helium) cryptocurrency.
This equipment is guaranteed for 1 year (see conditions below). No 14-day return of a hotspot already declared on the Helium network is possible, as the equipment is then considered to be personalised by the user and cannot be resold as is.

To get the best possible performance depending on the location of your Helium miner installation, it is recommended to use an antenna installed outside, as high and clear as possible on 360°.
The use of an antenna, correctly tuned to the frequency band used by the Helium network is also recommended, such as the 868 MHz tuned antenna OPA Design. This antenna is with a female N connector.
The Rock Pi hotspot is equipped with an RP-SMA female connector, not to be confused with an SMA connector. A male RP-SMA connector must be chosen to be compatible with this helium hotspot.
To connect the recommended antenna directly to the miner, the cable must have an RP-SMA male connector on one side (to go to the HS) and an N male connector on the other (to go to the antenna).
We recommend using a low-loss KSR400 (LMR400 equivalent) coaxial cable, of the shortest length possible for your configuration, such as this one: https://www.passion-radio.com/ksr400/rallonge-rpsmam-nm-1507.html

In the event of a hotspot failure after the 14-day return period and under warranty, Passion Radio offers a 1-year warranty on this equipment for quality defects or manufacturing faults (except in the case of warranty exclusions below), repair or replacement with identical or equivalent equipment, depending on availability, or a credit note or partial reimbursement depending on the age of the equipment, if the equipment is no longer available.
The guarantee applies within the framework of normal use and according to the conditions of use and the specifications indicated by the manufacturer of the material. The return costs are at the client's expense, Passion Radio will pay for the return of the equipment.
The guarantee does not cover breakdowns or defects resulting from
No 14-day return of a hotspot already declared on the Helium network will be possible, as the equipment will be considered as personalised by the user and impossible to resell as is.
What is the antenna connector on the hotspot?
The indoor unit is equipped with an RP-SMA female connector.
Is the 2GB memory sufficient for mining?
A hotspot in full activity consumes less than 1GB of RAM memory. With 2GB of memory the RockPi miner has enough RAM to operate.
A 4GB or 8GB hotspot will not perform any better than a 2GB hotspot with the same installation configuration.
The key point is the antenna, its tuning and line of sight.
What version of the RockPi hotspot do you have?
We only offer V2 with the correction applied.
Can I add 4G connectivity to my indoor hotspot?
No, the indoor unit does not allow the addition of a 4G modem. You can use a solution like a MiFi or a 4G to Ethernet module to achieve the same result.
How much internet data does the Hotspot use per month?
Currently, we estimate 30-50 GB per month.
Actual usage may be slightly lower or higher and will be updated as we start measuring more units.
As all hotspots become "hotspot light", data usage will decrease.
What antenna is included with the hotspot?
A 3dBi omni-directional antenna is included with the Nebra Indoor Hotspot, the specifications can be found in this manual.
Upgraded antennas can be purchased as an option below.
Can I use PoE power with this Indoor Hotspot?
If you wish to use PoE with the Indoor Hotspot, you will need an active PoE splitter that supplies 12V to the unit. You can also use passive PoE adapters as long as the power supply to the unit is between 9 and 16 volts and can deliver 15W of power.
How long does it take for my hotspot to synchronise with the network?
This time may vary depending on the speed of your Internet connection. However, in our tests, it takes approximately 24-48 hours for the initial sync to complete.
