AntRouter R3-LTC, a WiFi Router and Clock That Mines Too

25, Feb 2018

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.

BitMain AntMiner U3 Available Again, Comes With New Design

16, Jan 2015

BitMain has started selling the AntMiner U3 Bitcoin ASIC miner again with a slightly different design than the original first batch, other than that the specifications remain pretty much the same (with some minor differences in cited power usage). The new AntMiner U3 Batch 2 is available with a minimum order quantity of 20 units at a price of 38 USD (0.185 BTC) and the Batch 3 is with a minimum order quantity of just 5 units available at a price of 39 USD (0.19 BTC). The BitMain AntMiner U3 ASIC miners provide 63 GHS at about 60W with 1 Watt per GHS in the new specifications that are published by BitMain with a low noise level.

BitMain AntMiner U3 Specifications:
– Max Hash Rate: 63 GH/s ±5%
– Power Efficiency: 1Watt/GH/s on wall at 0.83V
– Voltage: DC 12V input, 6A
– Chip Quantity per unit: 4
– One 80mm fan
– Noise: ~25 DB at 25 °C ambient temperature
– Hashrate and VDD core voltage can be adjusted via cgminer command line
– USB connection
– 12V AC/DC power brick of 6A, but power line not included
– Certificate Compliance: FCC/CE

BitMain has these miners available for home users that want to have access to affordable priced and silent Bitcoin ASIC miners that want to play with them just for hobby, they are not designed to ROI due to their lower hashrate and not so great power efficiency. Since they are running batch 2 and 3 this means that there is interest in these little devices from users, though you probably would want to get a single unit to play with it and not buy a minimum of 5 or 20 units. This means that most end users will probably not be interested in directly buying AntMiner U3 from BitMain, but will look for some company reselling these at a single piece quantities.

BitMain AntMiner U3 Bitcoin ASIC Miner for Home Miners

BitMain has revealed a new 63 GHS AntMiner U3 SHA-256 ASIC miner designed for home users as the successor of the previously available USB stick miners that the company offered. The device is apparently made for home users that do not want serious noise levels or high power usage. It is more of an interesting and affordable device for users that are new to ASICs or just for a fun “toy”, don’t expect the U3 USB miner to actually make you some serious profit or something like that. The Antminer U3 is based on four BM1382 ASIC chips resulting in 63 GHS worth of hashrate and is priced at $56 USD per unit or 0.151 BTC at the moment (without shipping). The AntMiner U3 USB miners (connected to a PC via USB, not powered by USB) should start shipping on November 5th, or with other words less than 2 weeks from now. There is however a catch, if you want to order the BitMain AntMiner U3 directly from the manufacturer you will not be able to get a single unit, the minimum order quantity is 20 units. So this kind of defeats the purpose of directly ordering it from BitMain if you are an end user, but we are probably going to see some of BitMain’s partners also offering the miner for people that might be interested in purchasing single units.


BitMain AntMiner U3 ASIC Miner Specifications:

– Hash Rate: 63 GH/s at 0.75V
– Power Efficiency: 0.8 Watt/GH/s on wall at 0.75V
– Voltage: DC 12V input, 6A
– Chip Quantity per unit: 4
– One 80mm fan
– Noise: ~25 DB at 25 °C ambient temperature
– Hashrate and VDD core voltage can be adjusted via cgminer command line
– USB connection
– 12V AC/DC power brick of 6A, but power line not included
– Certificate Compliance: FCC/CE

Note that the noise level of these should be pretty low indeed at just about 25 Decibels, there is no exact power usage quoted, but it should be less than 70W which the supplied power adapter is apparently capable of as maximum. With the cited power usage of 0.8W per GHS the actual power usage should be close to about 50 Watts for the whole unit or maybe slightly more. The devices should be overclockable apparently through the cgminer command line, so there should be some headroom for increasing their hashrate with the expense of a bit more power usage. Again do note that these miners are low hashrate and low powers, designed to be silent and used by home miners just for fun and not as a means to make profit as they many not even be able to get you a return of investment in the foreseeable future.
