#HELIUM FOR MAC REVIEW HOW TO#

The first one (orange) seems to be the power indicator. There are two leds on the front of the miner.

The pairing seems not working a second time : during the 2 tries I had to do, pairing process was an immediate success on the first time but then I had to reboot and wait before being able to pair again with the miner.

The pairing button is placed between power supply and antenna so once everything is connected it is a bit complex to access (this is a really little issue).

The pairing process with the miner has been complex: I had some difficulties but they seems to come from the Helium application more than the Nebra Miner. The installation is like for any hotspot, it is made with the helium application.

Seeing this, I immediately through about unsoldering it and see how to use it in a DIY ! LoL But right know it’s not the time to investigate such kind of hack: The way it has been soldered is also quick and dirty.

You can’t miss the secure element on the board. This will be more difficult than getting a new SDCARD. This is good as this flash is fast and reliable but in case of problem all the CM3 will have to be changed. There is no SD CARD so the miner run on the CM3 internal Flash. It is a compute module 3 with 1 GB of RAM and 32GB of Flash. On the top right, you can see the raspberry PI. For an indoor usage with the WiFi access point located 5 meters around, this is not a problem. So It is really better to use it with the Ethernet cable. Compared to the RAK miner where the metallic box was a problem, here, we have a plastic box but a really low quality WiFi antenna in the dongle located inside the box. As a consequence the WiFi performance will not be really good. The 2 USB connectors are used for the WiFi connectivity and the BLE connectivity. There are 2 leds and the power connector also. You have the Ethernet connector and Radio connector on the front side. 2 USB connectors on the left and the secure element on the right. The Nebra motherboard has also the LoRaWan concentrator connector. You can see the Nebra mother board in the center, this one has a large connector for the Raspberry Pi handler on the back. You don’t really need to open it (once the radio connector is correctly screwed) so, I did it for you to see what it inside. Some miner has larger assembly problem according to the social network but nothing you can’t arrange on your own. But you need to make sure your antenna connector is correctly screwed or you will have to open the box and screw it correctly. The Batch #1 has some problem in the inside, I’m quite sure they will be fixed really quickly. It’s correctly finished from the outside, the big Nebra brand on it. The Nebra miner is a plastic box, a bit big compared to the RAK miner but nothing problematic. The WiFi is not the recommended solution for connectivity so it is better to have the cable coming in the package. It’s a really good choice to add a network cable as not all the miners have one and it is frustrating to be stuck because of it. Inside the Nebra box, a pretty nice package, you have the Nebra miner, the power supply with all the connectors for using it anywhere in the world (but this is a 868Mhz version) the radio antenna, a network cable and 2 stickers !
