Helium Mapper / Tracker - TTGO T-Beam

A TTGO T-Beam is an ESP32 development board that also integrates a SemTech chip for LoraWAN communication, and a Neo-6M GPS receiver...
Sounds boring right..?

Well in this case, we have turned it into a HELIUM NETWORK MAPPER (or Tracker)!

With this, you will be able to contribute to the Helium Coverage Mapping Project, or GPS track random cargo/assets through the Helium Network.

What does Mapping Network Coverage for Helium mean?

In short, you will be reporting physical areas that can send and receive LoraWAN signals within the Helium Network.
If you are old like me, you should remember some of the old Verizon TV commercials, and the "Can you hear me now?" guy. That's exactly what we are doing here, making sure there is network coverage and reporting that to the mappers.helium.com database.  So please join us in mapping out the coverage of the Helium Network, so we too can start bragging about the LoraWAN coverage we have!


What setup is involved?

When you receive the TTGO T-Beam, it will come loaded with a Fiz-Tech revision of an open source code modified to be used for the Helium Network.  So no programming of the actual device is needed.   
You will need to add the device to the Helium Console (console.heloium.com) using the 3 strings of numbers included with the device, the DEV EUI, APP EUI, and APP KEY. And then using functions and integrations, route that traffic/data to the Mappers or Cargo platforms.
If you do not have a Helium Console account, you can signup free and currently upon setup you will receive 10,000 Data Credits (0.10 USD).  These Data Credits are used to every time a end-device (such as the T-Beam) sends data through the network.  If you are just using the T-Beam, this will last you quite a while. You will be amazed on how cheap it costs to run devices on the Helium Network. 
A guide will be included with purchase. 


Can I use this for other things?

Yes!  You may use this device however you wish (so long as it is legal).  Use it to track fleets of vehicles, or hikes along a trail.  You may choose to reprogram it for any other purpose if you have the knowledge to do so.

 

What is the Warranty and Support?

- Up to 30 days after purchase, repair or replace deflective units. Buyer will pay for shipping defective unit back, and Fiz Tech will pay for shipping the repaired/replacement unit. 
- Most common issue can be related to screen, such as no display or freezes; though unit itself still operates.  Most of the time, a power cycle will correct.  If you have a solder iron, this can be a quick fix.
- Support for initial setup within console.helium.com and mappers.helium.com provided via YouTube / Written guide.  Live support within Official Helium Discord, and community support in #mappers channel.


All cases may have some small "defects" in the printing, such as burnt areas, or areas where print layers may not have formed correctly.  This has no effect on the integrity of case, just consider them "Birthmarks".   :)
