Last year we have tested and reviewed the FutureBit MoonLander USB Scrypt ASIC Miner and have found it to be a well-designed and working miner. Unfortunately with hashrate maxing at just about 1 MHS at that time it was not very up to date for practical use with mining profitability in mind. The good news is that there is a new version of the miner in the works – FutureBit Moonlander 2 and the new device will be more interesting specifications wise.

The FutureBit Moonlander 2 USB Scrypt ASIC miner is supposedly offering an efficiency of about 1.3 Watts per MHS and the device should be capable of delivering between 3 and 5 megahashes for Scrypt mining (depending on settings). With the recent peak of the interest in Litecoin we could be seeing increased interest in these devices as well. The new version of the USB Scrypt ASIC should most likely be available for orders in October with deliveries starting at the end of October or early November. The price is not yet fixed, but it will most likely be in the range of $40-$60 USD per miner.

Preliminary specifications of the miner:
– Hashrate: 3-5 MHS Scrypt performance per miner
– Power usage: about 1.5W per MHS for most of that range
– Operating frequency: core clock from 500 MHz to nearly 1 GHz!
– Operating voltage: fully customizable core voltage range from 0.6V – 1V
– Fully redesigned 5v->core voltage stage with about 95% efficiency
– Heavy duty/over speced parts were used to ensure wide range of operation (stick can be pushed to nearly 6mh if you can cool it)
– Status LEDs for power, TX and RX transmission
– Uses latest bfgminer 5.4 for control
– Will work with all Mac OS, Linux, and Windows based PCs, as well as RPi’s etc (and I will be offering easy to use pre-compiled binaries)

The crypto currency mining ASIC maker Bitmain is getting ready to launch a new Scrypt ASIC miner with shipping expected to start a bit later this month. The new device capable of mining Litecoin (LTC) and other Scrypt-based crypto currencies is called AntMiner L3+ and should be capable of delivering a hashrate of 504 MHS with a power usage of 800W. With the recent jump in interest and the price of Litecoin we are seeing a bit of a revival of the interest in Scrypt-based coins and this is apparently also the reason why Bitmain has prepared a new more powerful device.

The new Antminer L3+ is essentially double the performance and power usage of the regular AntMiner L3 model announced earlier this year. It offers essentially doubled performance by doubling the number of BM1485 ASIC chips from the 144 units in the L3 to 288 in the new L3+. The English website of Bitmain still hasn’t got the product listed, but their Chinese one has the device already listed with a price of 1.686 BTC per L3+ device that does not include a power supply. The shipping should start sometime in between April 15th and April 20th based on the data on the website. Early May deliveries (May 1st – May 10th) are also possible with a lower price of 1.261 BTC per L3+ device.

Bitmain AntMiner L3+ Scrypt ASIC Specifications:
– Scrypt mining hashrate: 504 MHS

– Power efficiency: 1.6J/MH ± 10% (at the wall, AC / DC efficiency of 93%, 25°C ambient temperature)
– Rated voltage: 11.6 ~ 13.0V
– Chip Type: BM1485
– Chip quantity per unit: 288 chips
– Number of boards in the whole machine: 4 pcs
– External dimensions: 352 mm (L) * 130 mm (W) * 187.5 mm (H)
– Machine weight (without packaging): 4.4kg
– Operating temperature: 0°C to 40°C
– Operating Humidity: 5% RH-95% RH, non-condensing
– Network connection: Ethernet
– Noise level: 75dB

Another interesting piece of information about the popular ASIC manufacturer Bitmain as apparently the company is planning to launch their first Antminer L3 Scrypt Miner. Some of you might remember that back in 2014 Bitmain was planning to launch Antminer L1 Sctypt ASIC miner, but that one never came into existence. Apparently back then the company reached a stage that allowed even without launching a product to continue working and get an even more efficient solution and here comes the L3. There is some information available about the device already, even though it is not yet officially listed on the English website of Bitmain (you can find a product page on the Chinese one).

You can find some photos and even some early performance results online from peopel that managed to get some early units apparently, including a tweet from charlie Lee who created Litecoin (LTC) about getting one of these devices. More general availability is expected sometimes in February probably because of the incoming Chinese New Year, so we are going to have to wait some more time. What is the most interesting thing about the Bitmain AntMiner L3 Scrypt ASIC miner is the efficiency that the device not only apparently promises, but also delivers – 250 MHS hashrate with just 400 Watt power usage. This makes is significantly more power efficient compared to its only competitor with a recent generation of Scrypt ASIC hardware available – Innosilicon A4 Dominator (280 MHS at 1000W). The price listed on the product page is 1.825 BTC or a little over $1600 USD at the current exchange rate. Do note that the Antminer L3 ASIC does come without a power supply, but with the power usage the device has it does not require expensive and harder to find power supply, a decent 500W PSU should do just fine.
