Helium Hardware Definitions

This repository contains the python file that contains a GPIO map for all of the different hardware combinations to be supported by the Nebra Helium Hotspot Software.

All numbers below are their GPIO / BCM Numbers, not physical pin numbers.

Note: Light hotspot software will also work on all models listed as type "full".

Nebra Hotspots

Model ENV Identifier SPI Bus Reset Pin Status LED Button Type Cellular Notes
Nebra Indoor Hotspot Gen 1 NEBHNT-IN1 1.2 38 25 26 Full False CM3 based
Nebra Outdoor Hotspot Gen 1 NEBHNT-OUT1 1.2 38 25 24 Full True CM3 based
Nebra Pi 0 Light Hotspot S NEBHNT-LGT-ZS 1.2 22 24 23 Light False SPI Based Ethernet
Nebra Pi 0 Light Hotspot X NEBHNT-LGT-ZX 1.2 22 24 23 Light False USB Based Ethernet
Nebra Beaglebone Light Hotspot NEBHNT-BBB 1.0 60 31 30 Light False In Planning
Nebra Pocket Beagle Light Hotspot NEBHNT-PBB 1.0 60 31 30 Light False In Planning
Nebra Hotspot HAT RockPi4 NEBHNT-HHRK4 1.0 149 156 154 Full False In Planning
Nebra Hotspot HAT RPi NEBHNT-HHRPI 0.0 22 24 23 Full False Should be compatible with 3+ & 4
Nebra Hotspot HAT RPi LIGHT NEBHNT-HHRPL 0.0 22 24 23 Light False Light is compatible with all 40 pin headers
Nebra Hotspot HAT Tinkerboard 2 NEBHNT-HHTK 2.0 167 163 162 Full False Light would be compatible on TK1

Third Party Hotspots

We may be adding in support for other vendor's hotspots to use our software soon. Here are the variables for those.

These would also depend on their SOCs being supported by Balena.

Model SOC/SBC ENV Identifier SPI Bus Reset Pin Status LED Button Type Cellular Notes
Rak Hotspot Miner BCM2711 (Pi4 2gb RAM) COMP-RAKHM Full False Only Compatible with V2 hotspots with ECC Key.
OG Helium Hotspot BCM2711 (Pi4 2gb RAM) COMP-HELIUM Full False
Syncrobit Hotspot 1 (Pi) Full False
Syncrobit Hotspot 2 (RK) Full False
Bobcat Miner 300 Full False
Sensecap M1 BCM2711 (Pi4 2gb RAM) COMP-SENSECAP Full False

DIY Hotspots

The following DIY options are also supported for light hotspot software only.

Please note, DIY Hotspots do not earn HNT.

Model SOC/SBC ENV Identifier SPI Bus Reset Pin Status LED Button Type Cellular Notes
Pi Supply IoT LoRa Gateway HAT RPi DIY-PISLGH 0.0 22 Light False Any pi with 40 pin header
RAK2287 RPi DIY-RAK2287 0.0 17 Light False Any pi with 40 pin header

Install

This package is automatically built and published to our PyPI repo using GitHub Actions. Installing the package is as simple as:

pip install hm-hardware-defs

You can also install a specific version using:

pip install hm-hardware-defs==0.1.4

Usage

You can use the hardware definitions within your project by importing the package into your python script as follows:

from hm_hardware_defs.variant import variant_definitions

Important Notes

This package is used in a number of Nebra software repos:

Contributing

If there is hardware that you would like to be supported that is not listed here, please complete one of the following:

  • Create an issue on this repository which has the name of the Hotspot, or DIY solution. With at a minimum a link to a pinout of the device and which SBC it is to be used with.
  • Fork this repository and add the device to the array in variant.py, update the table above and then create a pull request.
