ASIC miner Antminer L3+: characteristics, profitability and payback

Appearance and technical characteristics of Antminer l3

Antminer l3 was developed by specialists who had previously created a chip for mining BTC. With a performance of 250 Mh\sec, it consumes about 800 W of electricity, which is a very economical indicator.

The model uses 288 microcircuits, which is almost twice as many as competitors. The result of the introduced innovations was an increase in mining efficiency by 100%.

Using Antminer l3 allows you to minimize overhead costs when calculating the Scrypt algorithm and thereby increase the profitability of your work.

The device is housed in a durable and compact steel case. This solution provides protection from mechanical damage and extends service life.

Main characteristics of Antminer l3:

• computing power - 250 Mhash-sec.;
• number of chips on the processor - 288;
• energy consumption level - 800 W;
• noise level - 75 dB;
• operating voltage - from 11 to 13 V;
• operating temperature range - from 0 to +40 degrees;
• case dimensions: 130 x 352 x 197.5 mm;
• weight - 4.4 kg;
• efficiency - 1.6 J;
• price - from $1,500 to $2,000.

On the front and rear panels there are fans for the cooling system with a blade radius of 6 cm, operating at a speed of 3 thousand revolutions. They are indispensable in cases where it is necessary to use the full amount of computing power.

The design provides additional slots for connecting integrated circuits. This allows you to turn the Antminer l3 into an entire mining rig housed in its small and lightweight body.

In the center of the panel there are two color indicators that instantly signal device malfunctions, a button for automatic IP address detection, and an input for an RJ-45 cable.

One of the technical features of the ASIC is a two-level setting of the cooling system, which works using special software. The correct choice of settings can significantly reduce energy consumption and reduce noise levels.

Miner Antminer L3 +: profitability and payback

The asic Antminer L3+ miner with USB 2.0 was developed in 2020 to calculate Litecoin, this currency will have the highest return. This is due to the relative ease of production and the well-increased exchange rate. Some users interpret the Scrypt algorithm as a reason to connect equipment to mine other digital versions. But at the moment there is no alternative to LTC profitability.

The data for calculating the profitability of Litecoin mining on a video card is changing. Based on numbers such as:

1. The network hash coefficient is 22177 GR/s.
2. Exchange rate LTC/USD 55–56.
3. Block reward 25 LTC.

All that remains is to subtract the cost of electricity and it turns out that the asic miner Antminer L3 + brings its owner from 0.7–0.9 LTC units per day. This figure must be multiplied by the current coin exchange rate in dollars. The payback period is from 5–6 months, although taking into account the increase in complexity and possible exchange rate fluctuations, it is better to round this period to 6–7 months. In addition, breaking even depends on the purchase price and quality of the device.

Users who work with several Antminer L3+ note a pattern - if the ASIC miner has worked for 2 months, then you can be sure of further operation without complaints. Failures that occur with the ASIC miner Antminer L3 + in the first weeks are repaired under warranty. Chinese manufacturers set a service period of 3 months. So it is better not to remove warranty seals during this time. Miners who are just starting to work in the field of computing should carefully consider the choice of their first machine and take care of guarantees.

What coins can be mined on Antminer l3

As already mentioned, l3 was tailored specifically for the popular ltc cryptocurrency.

This is a universal coin with a larger block size compared to BTC, which makes online payments much faster. Other coins that can be mined on l3:

• dogecoin;
• syscoin;
• belacoin;
• einsteinium, etc.

An increase in the number of resources involved in computing Scrypt significantly complicates the hardware implementation of specialized mining devices. Such a solution, according to the developers of the algorithm, should prevent the possibility of developing cheap ASICs that would allow large amounts of power to be concentrated in one hand.

But Antminer l3, which, judging by user reviews, shows excellent results, became a real technological breakthrough and actually pushed video cards out of the market. Even despite the fairly high price, buying a new ASIC is much more profitable than buying outdated GPUs.

Weight and size of Antminer L3+

The weight of the L3+ is ~5kg, which makes it less cost effective compared to the A4+ at ~4kg. This difference may not seem like much, but when calculating shipping costs, it makes the L3+ significantly more expensive.

L3+ is slightly larger (352mm * 130mm * 187.5mm) than LTCMaster (350mm * 125mm * 155mm). This is another thing to consider when deciding on delivery. However, taking into account the very uncompetitive price difference, L3+ is still the better value.

Learn more about the benefits of ASIC Antminer L3

1. Simple and reliable connection and startup of the device.
2. The minimum necessary additional elements required for operation (only a power supply and twisted pair).
3. The presence of a restart function that automatically restarts the device after eliminating unexpected power failures.
4. Compact body, thanks to which Antminer l3 can be easily placed in an ordinary room and just as easily transported to another place.
5. Fast payback achieved through high energy efficiency and excellent price-benefit ratio.
6. Reliability in the robot. Firmware updates are required very rarely, and there is virtually no downtime.

Connection and configuration procedure

For a stable, uninterrupted connection to the miner, it is recommended to purchase a proprietary Bitmain APW3 power supply. The second condition is the availability of reliable high-speed Internet. It can be connected via twisted pair (there is a connector for it on the l3 case).

The ASIC case must be located at a distance of 20-25 cm from the wall for the fans to operate normally, otherwise the cooling will be ineffective.

After launch, you need to scan the local network through the settings in the interface and determine the IP of the device, and then enter the address in the browser.

To get started, you need to go to the settings of the selected mining pool, enter the address, come up with a password and login, and click Save. After this, the ASIC will reboot and mining will begin.

Note: when setting up the equipment, pay attention to an important parameter that is responsible for the reliability of operation: opposite the line “Stop running when temperature is over 80”, enable the “chack-box” protective function - turning off the miner when it overheats. After all mechanisms have cooled down to acceptable values, system operation automatically resumes.

Briefly about other devices for mining ltc and comparison with L3

1. Antminer L3+ was created by Bitmain based on the VM1485 microprocessor. It has a performance of 504 mh\sec (an increase of 5% is possible), equipped with 288 chips, two powerful coolers and a power supply. Like other Bitmain models, it is small in size, simple and reliable in operation.
2. A4+ LTC Master. ASIC manufactured by Innosilicon for ltc mining with a performance of 620 mh\sec, power consumption level of 0.75 kW, two powerful fans. Sold in small quantities, after pre-order you need to wait for production and delivery. Features of the model: high hashrate, low noise, reliability.
3. Innosilicon A6 LTC Master. An improved version of the previous 2020 model with higher performance (1.23 gh\sec) and electricity consumption (1.5 kW). The main disadvantage of the A6 is the high price ($6.3 thousand)
4. L21. 2020 model from BW. Average performance - 550 Mh\sec, 28 NM chips, two cooling fans, power consumption level - 0.95 kW. A reliable device with fairly high performance at a price of $2,640.

Characteristics of antminer L3

Antminer l3 weighs only 2.5 kilograms, while A4 Dominator weighs about 9 kg. This is another advantage of L3 - due to weight, delivery speed is significantly reduced. Another distinctive advantage of L3 is its relatively low noise level: 60 dB. While L3+ produces between 75 and 95 dB. The device will not be heard by your neighbors, but it is still impossible to keep it in the bedroom. In terms of dimensions, L3 is also quite convenient - 23x13.5x16 cm. However, L3+ is still somewhat smaller. The device uses BM1485 chips. There are 14 chips per device. Each device has 4 boards. L3 operating temperature ranges from 0°C to 40°C. L3 will use the Scrypt algorithm.

How Antminer l3 appeared

Bitmain has been hatching plans to create a miner for Litecoin mining since 2014. It was then that rumors first appeared about the imminent launch of Antminer l1 for script mining. But at that moment something grew together, and the ASIC was never born. And now, three years later, at the beginning of 2017, publications about ASIC for scrypt resumed in the media. This time everything worked out: soon miners could already make an advance payment for the Antminer l3 model - an improved version of the never released l1 from the same manufacturer.

Sales of the scripted device began in April 2020 and coincided with the beginning of the active growth of the ltc exchange rate. This led to a rush of demand for a new ASIC. Surprisingly, even the super-productive Chinese were unable to meet the needs of everyone, and a shortage formed on the market. Many miners even had to travel to China to buy equipment locally, since there was no other way to do it.

As a result, counterfeit l3 antminers appeared on sale, which were quite effective, but failed very quickly. Used equipment was sold on the market at a speculative price, far exceeding the manufacturer's price. This is not surprising, because the new devices provided speeds of up to 250 Mx/sec, which significantly exceeded the speed of GPUs running the Scrypt algorithm.

Price and payback of Antminer L3

Of course, every potential buyer of Antminer l3 is interested in how quickly the investment will pay off. During 2018, Litecoin gradually lost value, as did almost all other cryptocurrencies. Today, one ltc is trading at about $54, which is almost six times less than the January peak ($300). Of course, this directly affects the profitability of mining.

Litecoin rate over the last three months according to Coinmania

To have an idea of ​​the amount of possible income, use an online mining profitability calculator, for example, WhatToMine.

Those who did not have time to order a new ASIC at the time of release can today only purchase it on the secondary market: on Ebay, Amazon and similar trading platforms, or in specialized companies - official distributors of such equipment. The light weight and dimensions of the device allow you to save on delivery, especially when it comes to long distances.

But taking into account the decrease in mining profitability and the fact that an improved and more productive Antminer l3+ model has already been released, you should not pay more than $1 thousand, and even then with a guarantee of fast delivery, because the formula “time is money” is especially relevant in mining. It may be better to wait for the stable positive dynamics of the cryptocurrency market, which, according to experts, should come very soon.

Payback of Antminer L3

The rate of the Litecoin cryptocurrency is constantly growing, upward trends are characteristic of all coins included in the TOP of the most popular. At the moment, 1 LTC token is valued at approximately $120, naturally, if the price continues to rise, then mining efficiency will increase.

Don’t forget, L3 – HR 540 Mh/s miners were released last year, are they capable of making a profit now? To get an objective answer to this question, you should carefully analyze the profitability of the ASIC device. You can do this manually or use an online calculator.

On average, the mining equipment in question can bring 0.7-0.9 LTC per day. These values ​​should be multiplied by the current cost of the cryptocurrency = 0.7 * 120. On average, the device will pay for itself in about six months. However, it is worth taking into account the increase in network complexity and cryptocurrency fluctuations, so an error of 1-2 months is allowed. Do not forget that the payback period depends on the initial cost of the ASIC.

In general, even in 2020, the miner is capable of generating impressive income for its owner.
