It seems that Bitmain is moving more into the direction of making smaller and lower power miners that do more than just mine crypto currencies and their upcoming AntRouter R3-LTC is a proof of that. The company has previously released a WiFi router that mines Bitcoin and then Litecoin, but these were pretty low power devices. The upcoming AntRouter R3-LTC adds improved specs for mining Litecoin and as a WiFi router and even adds a handy clock on the front of the device. The device is based around the BM1485 Scrypt ASIC chip, Bitmain’s Litecoin Application Specific Integrated Circuit (ASIC). We cannot say there is no potential in devices that do something useful and mine as well, these however have to be cleverly designed and made in a way so that mining does not impact their normal use.

The device offers 300 Mbps 2.4 GHz 802.11g/n WiFi as a router and comes with 6x BM1485 ASIC chips for mining inside capable of delivering 9.9 MHs as Scrypt hashrate with a power consumption of 23.2 Watts according to the specs. On yes and it comes with a LED clock on the front to show you the time, so it is essentially a 3-in-1 product that can sit on your desk and mine while it provides you with Internet connectivity and shows yo the time. The only not so great thing about the device is the noise level rated at 50dB at 1m from the ventilation ducts, at an ambient temperature of 30°C, in a silent room. We highly doubt anyone will be willing to have a noisy WiFi router on the desk, even if the device is also earning some money by mining Scrypt cryto currencies such as Litecoin. The last and most important thing as usual is the price of the device, we don’t know how much it will cost you as Bitmain has not yet announced pricing.

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%)

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 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-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
– 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)
