MatchX M2 Pro LPWAN Crypto-Miner Supports LoRaWAN and Cryptocurrency Mining

A few years ago, I received MatchBoX outdoor LoRaWAN gateway for review, and eventually tested it with RAK811 LoRa tracker once I got a node to play with, and made sure I did not break any local laws.

But now the company has come up with an unusual gateway with its MatchX M2 Pro LPWAN Crypto-Miner that acts as a traditional LoRaWAN gateway, as well as a cryptocurrency miner. I’m a bit perplexed by the solution as miners are notoriously power-hungry, but let’s have a look.

MatchX M2 Pro specifications:

  • SoC – NXP i.MX 6UL (MCIMX6G2CVM05AB) single-core Arm Cortex-A7 processor @ up to 528MHz
  • System Memory – 256MB DDR3 RAM
  • Storage – 256MB NAND FLASH, optional SSD up to 32GB or industrial SD-Card
  • Networking & Wireless Connectivity
    • LoRa Radio – SX1302 chipsets, 16 frequency channels Supports EU868, US915, AS920, AS923, AU915, KR920, IN865 regions
    • 2.4Ghz 802.11b/g/n WiFi 4
    • GPS via UBlox Max 7Q GNSS receiver with additional LNA
    • 10/100 Mbit Ethernet with 24V POE support
    • 4x SMA waterproof antenna connectors
  • USB – 1x USB Type-C port with USB PD power and console UART support, 1x USB Type-A host port
  • Sensors – 3-Axis accelerometer, pressure sensor, temperature sensors, voltage, and current monitoring
  • Misc – Reset Button,
  • Power Supply – 24V DC passive PoE or USB-C PD rev 2.0 up to 22V
  • Power Consumption – 3.5W on average, peak 6W
  • Temperature Range – -40ºC to 85ºC
  • Enclosure – ASA plastic, anti-UV
  • Dimensions – 226 x 101 x 73mm (without antenna)
  • Weight – 400 grams

There’s no ASIC for cryptocurrency mining, and from a hardware point-of-view, this looks like a typical LoRaWAN gateway. But then we have this comparison table between a crypto-miner and MatchX M2 Pro gateway.

That looks like a non-sensical comparison to me as besides the acquisition cost of ~3,000 Euros, both are completely different beasts. But I think the important part is at the asterisk under the table: “comparisons are difficult when comparing PoW and PoS models”. I’m not really knowledgeable in cryptocurrencies so let’s find out what this means:

In POW (Proof-of-Work), the miners solve cryptographically hard puzzles by using their computational resources. In POS (Proof-of-Stake), instead of miners, there are validators. The validators lock up some of their Ether as a stake in the ecosystem. Following that, the validators bet on the blocks that they feel will be added next to the chain. When the block gets added, the validators get a block reward in proportion to their stake.

So the way I understand it, PoS does not require lots of processing power, while PoW used with cryptocurrencies such as Bitcoin does. This seems much more sustainable since Bitcoin’s electricity consumption matches the one of the Czech Republic as of August 2020.

If you read further we’ll find out MatchX M2 Pro relies on MXC DataDash App for Android and iOS which allows you to monitor your earnings via MXC, a “secure and reliable cryptocurrency exchange for trading Bitcoin, Ethereum, Litecoin, EOS, TRON, USDT, XRP, etc”.

So I suppose companies can set-up a network of MatchX M2 Pro LPWAN crypto-miner gateways in order to get some income from their gateways. There’s no mention of expected returns, and if I understand correctly it will depend on the number of transactions going through the gateway. The company claims over 20,000 LPWAB crypto-miners have been pre-order so far. More details may be found on the product page.
