NerdMiner V2 Dongle 78Kh SHA-256 Bitcoin Miner: Product Overview
What Is the V2 Dongle 78KH and What Does It Mine?
The NerdMiner V2 Dongle 78Kh is a dedicated SHA-256 ESP32 learning miner for Bitcoin & Bitcoin Cash. Based on the open-source NerdMiner project. This model belongs to the NerdMiner V2 Series.
Is the V2 Dongle 78KH Right for Your Setup?
Mining starts with power. A competitive electricity tariff or surplus renewable generation can give your operation a useful cost advantage, while higher electricity prices can make an otherwise capable miner uneconomic. Compare your rate and chosen coin in the earnings table, allowing for cooling, pool fees and any other operating costs.
Prefer to avoid the day-to-day work of running your own mining site? Our managed ASIC hosting services offer an alternative, with power, cooling and monitoring handled at the facility. Explore current locations and rates, then speak to our team to confirm compatibility, availability, minimum quantities and any additional fees.
Check the manufacturer’s electrical, cooling and environmental requirements before choosing an installation location.
Confirm the power supply, leads and cooling equipment included with your exact variant, and obtain its manufacturer’s installation manual before arranging the installation.
Which Coins Can the V2 Dongle 78KH Mine?
Mining Compatibility
Mining on the SHA-256 algorithm, you can secure Bitcoin (BTC), Bitcoin Cash (BCH) and AuxPoW siblings such as DigiByte SHA (DGB), eCash (XEC), Peercoin (PPC) and Fractal Bitcoin (FB); you can also earn Bitcoin and other coins by selling your SHA-256 hash-power on the NiceHash Hashpower Marketplace (Nicehash-SHA-AB).
How SHA-256 Mining Works
SHA-256 is the cryptographic hash function used in Bitcoin mining. Bitcoin applies it twice to a block header, and miners repeatedly test candidate headers until a result meets the network difficulty target. Dedicated ASIC hardware performs this work at scale. For equipment comparisons, hashrate describes the amount of hashing work a machine performs, while efficiency describes the energy needed for that work. Compatibility also depends on the network and mining protocol supported by the device and pool.

Coin and merged mining support depend on the network, pool and firmware. Selling hashpower through a marketplace is different from directly mining its payout coin.
About NerdMiner
NerdMiner V2 Dongle 78Kh is based on the NerdMiner project, part of the NerdMiner V2 Series.
Project Background
NerdMiner is a free, open-source project maintained by BitMaker-hub. It uses small ESP32-based devices to demonstrate Bitcoin solo mining and display mining and network information. The project is primarily intended for learning and experimentation, with publicly available firmware and support for several boards. NerdMiner identifies the project rather than a single manufacturer, and its microcontroller-based hardware should not be confused with a high-performance ASIC miner.
