- 1 X Nebra Light Hotspot
- 1 X LoRa Antenna
- 1 X International 12V DC Power Supply
The Nebra Light Hotspot comes in three hardware versions:
|868 MHz||EU868, IN865, RU864|
|915 MHz||US915, AU915, AS923, KR920|
The frequency is set upon initialisation by the Helium Network.
The Nebra Indoor Hotspot is 150x150x50MM In size when nothing is connected.
Approximately 175x150x50MM space is required when accounting in space required for connectors.
- 9-16V @ 15W DC 6.5MMx2.0MM Barrel Jack
- LED Indicator.
- Interface Button
- RP-SMA LoRa Connector
- Ethernet Connector
The Nebra Indoor Hotspot has a status indicator as shown above.
The Top LED will act accordingly:
- Off - Software has not started yet.
- On - Operating as normal
- Slow Blinking - Bluetooth Pairing is enabled
- Fast Blinking - There is potentially a fault. Please check diagnostics page.
The Bottom LED acts accordingly:
- Off - Unit is receiving no power.
- On - Unit is powered up.
The Nebra Indoor Hotspot has a button on the back of the unit.
This is used to re-enable bluetooth pairing on the hotspot, hold the button in for approximately 15 seconds then release to start pairing. The top light should start blinking slowly if successful.
The Nebra Hotspots run a customised software to provide high reliability and ensure your units are as up to date as they can be.
Approximately your hotspot will update once a week in an automatic process, we will announce updates via various social media platforms when they happen.
The software is open source at https://github.com/nebraltd/helium-miner-software
We are working on getting the Nebra Indoor Hotspot certified in multiple regions. As we have results from the certification process we will post them here.
