Bitronics review
NerdMiner and Bitaxe, built in Barcelona
The story
Bitronics started in Barcelona in July 2023, set up by the electronics designer who goes by Bitmaker, and is the shop behind the NerdMiner and a series of its own open-source home miners: Bitaxe, NerdAxe, NerdQAxe and NerdOctaxe, from a 78 kH/s lottery miner to over 12 TH/s. Unlike a reseller, the team designs, builds and assembles the devices itself and ships from Spain, so within the EU without import duties, with prices in euros. The flip side is the size: a small team, terms that only mention returns for transport damage or defects, and no separate warranty page. If you want a home miner built in Europe, this is a good address; if you want an industrial ASIC, it is not.
What they stand for
- Own design and assembly, open-source hardware
- Ships from Spain, free from €150 (ES) or €350 (worldwide)
- Barcelona — active since 2023
Returns only for transport damage or defects, by email; the terms state no period and no warranty length. Small batches, so sometimes sold out or on pre-order.
