According to the website, which monitors bitcoin node performance worldwide, the Bitnodes Hardware B1 model comes equipped with the latest version of Bitcoin Core and is said to be a "low footprint quad-core single-board computer built and configured to operate a dedicated bitcoin full node".

In interview, Yeow said:

Consuming 2.5 watts during normal operation – a typical desktop computer uses  65 watts – the $168.00 node will enable users to contribute to the bitcoin network by relaying bitcoin transactions across the globe

Its rival, Bitseed, launched it's first plug-in node launched in March. That product, slightly cheaper at $149, is credited with using less than 10 watts of power – four times more than Yeow's node.

Earlier this month, Bitseed also announced it was open-sourcing the creation of its new plug-in node, asking contributors to help develop its product in exchange for rewards.
