If you remember a while ago we have talked about the 550 MHS BW-L21 Litecoin (Scrypt) ASIC Miner as an interesting alternative to Bitmain’s AntMiner L3+ Scrypt ASICs. Unfortunately back then these were hard to order as there was a minimum order quantity of 100 units and not an easy and straightforward way to order them. This is apparently about to change as the manufacturer of the devices Biwang Electronic Commerce Co. (BW) has appointed the Australian company Block Assets Limited trading as HyperBit as their Worldwide Retail Distributor for the L21 ASIC miner. So finally some competition for BitMain in the home mining segment and more options for the small miners to get back into the Litecoin mining…

You can currently order the 550 MHS BW-L21 Litecoin ASIC miner from HyperBit at a price of $2690 USD in single unit quantities and get it delivered worldwide with a shipping set to start on 30th of November for the current batch of miners. The L21 is apparently the current leader in terms of performance Litecoin Application Specific Integrated Circuit (ASIC) miner on the market with 550 MHS hashrate and with just 900W of power usage. It is not clear what the situation with the power supply is at this point however, is there one included (no mention), but a PSU does appear on one of the product photos. Most likely you would need to buy the PSU separately, one that does provide at least 1000W of power and comes equipped with at least 6x 6-pin PCI-E power connectors. Do note that all orders are being shipped directly from the manufacturers location – Shenzhen, China.

BW-L21 Scrypt ASIC Specifications:
– Hash rate: 550MH/s (+- 10%)
– Power consumption: 900W (+- 10%)

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.

– Rated voltage: 11.6 ~ 13.0V
– Chip Type: BM1485
– Chip quantity per unit: 288 chips
– Number of boards in the whole machine: 4 pcs
