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 recent return of interest in Litecoin (LTC) and the growing price has apparently also sparked interest for more up to date ASIC miners and there is one more contender now available apparently. Here comes the BW-L21 Litecoin (Scrypt) ASIC Miner from BW.com promising to deliver up to 550 MHs with 950W of power usage. The ordering process for these devices however is not that easy apparently, there is a minimum order quantity of 100 units and the price is about 2500 USD. You need to contact BW by email in order to arange an order and make the purchase, though with 100 units MOQ this is hardly interesting for small home miners. Bitmain’s AntMiner L3+ Scrypt ASIC miner is still much more attractive to small miners that want to get just one or a couple of units, that is if you manage to buy one when new batches are being released.

BW.com BW-L21 Specifications:
– Hash rate: 550 MHS +/- 10%
– Power consumption: 950 W +/- 10%
– Power efficiency: 1.727 J / MHS
– DC voltage input: 12 VDC +/- 5%
– ASIC chip type: 28nm LTC ASIC chip by BW.com
– ASIC chip quantity per unit (miner): 144 chips
– Number of hash boards per unit: 4 hash boards
– Cooling: 2x 120mm x 38mm fan, 3000rpm (front and back, in a push-pull configuration).
– Weight: 4.8 kg
– Dimensions: 329mm (L) x 127mm (W) x 159mm (H)

We have been keeping track on the development of the new Innosilicon A4 Dominator Scrypt ASIC miners since the initial announcement back in November last year and it is time for another update. It seems that Innosilicon is starting to take pre-orders for the final ASIC miners with shipping expected to start in September and there is already a thread on Bitcointalk about a group pre-order that you might want to check out if interested. In the past we have tested the previous generation of Innosilicon A2 Scrypt ASIC miners in the form of the 86 MHS A2BOX Innosilicon A2 Scrypt ASIC Miner that was consuming about 1000 Watts of power, so we can see what the development is and how good actually the new generation is going to be. A solid first generation Scrypt ASIC miner that was built well and performed really good when it was released with the only drawback being the very high initial price of the device, so we were anticipating another good solid product with much better specs when the first A4 details surfaced.

The initial announcement from last year claimed that the A4 Dominator is so efficient that it should be able to deliver about 850 MHS for Scrypt mining with 1020W of power usage. This was really impressive number and really caught our attention, especially considering that the first generation A2 Terminator miners were able to achieve just about 1/10 of that hashrate with the same power usage. A little bit later, in March this year, there was an update on the power usage and efficiency of the new A4 ASIC chips that has significantly lowered the initial numbers – down to 400 MHS from 850 MHS per kilowatt of power. Although the expected performance was lowered more than half it was still a pretty impressive number, but unfortunately this was not the final change and now we have a new number available. Apparently the final product will only be capable of about 260 MHs per 1 KW of power and be available for about $1800 USD without shipping and with power supply not included in the price. While the final performance per KW of power usage is not that bad either, we are not as excited as we were with the initial announcement or the March update. At 260 MHS per 1000 Watts things aren’t that bad, but with these specs we are not going to be pre-ordering one of these miners for sure. Maybe we are going to try to get one unit to test when they come out if it is not a pain in the ass to secure a single unit order.
