The Antminer L3 series is a line of Litecoin mining hardware developed by Bitmain. The series was first released in 2017 and has since become one of the most popular Litecoin mining ASICs on the market. The Antminer L3, L3+, and L3++ are all part of this series and offer different levels of performance and efficiency.

Antminer L3

The Antminer L3 was the first in the series and was released in 2017. It has a hash rate of 270 megahashes per second (MH/s) and consumes 800 watts of power. The L3 is a relatively noisy miner and is not ideal for home use.

Antminer L3+

The Antminer L3+ was released in 2018 and is an improved version of the L3. It has a hash rate of 504 MH/s and consumes 800 watts of power. The L3+ is slightly more efficient than the L3 and is also quieter.

Antminer L3++

The Antminer L3++ was released in 2019 and is the most efficient miner in the L3 series. It has a hash rate of 580 MH/s and consumes 800 watts of power. The L3++ is also the quietest miner in the series.

Profitable Custom Firmware for L3, L3+, L3++

In addition to the stock firmware from Bitmain, there is also custom firmware available for the Antminer L3, L3+, and L3++. This firmware can increase the hashrate by 20-30%, making the miner more profitable. However, it is important to note that custom firmware can void the warranty and may damage the miner if installed incorrectly.


The following table compares the three miners in the Antminer L3 series:

Feature Antminer L3 Antminer L3+ Antminer L3++
Hashrate 270 MH/s 504 MH/s 580 MH/s
Power consumption 800 watts 800 watts 800 watts
Noise level Loud Moderate Quiet
Custom firmware Available Available Available
Hashrate increase 20-30% 20-30% 20-30%

The Antminer L3 series is a popular choice for Litecoin miners. The L3++ is the most efficient miner in the series and is also the quietest. However, it is also the most expensive. The L3+ is a good choice for those looking for a compromise between performance and efficiency. The L3 is the least efficient miner in the series, but it is also the cheapest.

Which Antminer L3 Series Miner is Right for You?

The best Antminer L3 series miner for you will depend on your individual needs and budget. If you are looking for the most efficient miner, the L3++ is the best option. If you are looking for a compromise between performance and efficiency, the L3+ is a good choice. If you have a limited budget, the L3 is the cheapest option.
