Helium RAK Miner review

Rak Wireless Helium Miner v2

Rak Wireless is one of the Helium miner provider, currently the main one. This miner is based on a Rapsberry PI 4 but we will see that it’s not the only part in the miner as Helium Blockchain is not about computing but radio communications.

So the Rapsberry Pi is not the most important parts of the machine, it’s the LoRa concentrator, a piece of technology capable to listen simultaneously on 8 different radio channels and decode really low level signals around -139dBm, basically 0.00000000000001 mW of signal power…

In this post we will detail the technical details about this miner and the interesting aspects. I will also detail my installation experience, this one is not especially specific to RAK as the installation process is quite similar with all the different miners.

In term of radio, the different miner are equivalent and in term of processing the power of a Raspberry Pi 3 is good enough to run the blockchain. More over in the coming month the addition of the Validator in the block chain will drastically reduce the number of complex operation inside the miner. As a consequence, the performance is not an important criteria. This is to say, currently the tech specifications are not really important in the miner choice and I won’t detail a lot that part.
