HTC Reportedly Manufacturing Google's Nexus 9 Tablet

HTC Reportedly Manufacturing Google’s Nexus 9 Tablet

WSJ.D reports today that Google’s upcoming Nexus 9 tablet will be manufactured by HTC. The last HTC tablet was the Flyer back in 2011, so the Nexus 9 marks the end of HTC’s three year hiatus from the Android tablet market. This also reflects Google’s desire to team up with a variety of partners for their Nexus devices, so as to avoid becoming dependent on any one particular company. HTC manufactured the original Nexus One smartphone back in 2010, but in the interim we’ve seen Nexus devices from ASUS, LG, and Samsung. Samsung in particular has made more Nexus devices than any other company, but considering Samsung’s already large presence in the Android market it’s understandable that Google might want to look for other options.

There’s little in the way of official specifications for the Nexus 9, but if you remember earlier this month when NVIDIA announced it was suing Samsung and Qualcomm, the legal documents (since redacted) made specific mention of the Nexus 9 and the Tegra K1 processor. That’s a particularly interesting choice, as NVIDIA already has their SHIELD Tablet with Tegra K1, which ships with an 8-inch display. What we don’t know is if the Nexus 9 will use the same Tegra K1 that’s currently in the SHIELD Tablet, or if it will be a new variant sporting Denver CPU cores. The latter would seem more likely, as otherwise the Nexus 9 would essentially be a slightly larger version of the SHIELD Tablet, albeit with different styling (and of course no MicroSD slot).

Putting a Tegra K1 in the Nexus 9 may also be something of a “mea culpa” from Google to NVIDIA. After the Tegra 3 NVIDIA had little success in getting Tegra 4 into devices other than the SHIELD handheld, and while NVIDIA has been somewhat infamous for saying, “Wait for the next Tegra – that will be the one to beat,” Tegra K1 for a change is actually living up to the NVIDIA hype. The result is that it can be difficult to find the SHIELD Tablet at its $299 MSRP (though Newegg has inventory it appears), so supply at present has not been able to fully keep up with demand. It’s also not too much of a stretch to imagine the Nexus 9 being the launch vehicle for Android L, and at the recent NVIDIA Editors’ Day where we were briefed on GM204, there was at least one conversation that suggested Tegra K1 would be one of the first (if not the first) SoCs to get Android L.

Whatever the hardware inside the Nexus 9, Google’s Nexus devices have traditionally sold quite well so HTC should see much better sales figures compared to their Flyer tablet. Google also tends to be very hands-on with the designs of Nexus devices, the result being that there generally aren’t any major flaws compared to other smartphones or tablets. There’s no information or screenshots for the Nexus 9 at present, but this collaboration has clearly been going on for more than a few months so we expect an official announcement of the Nexus 9 can’t be too far off – just in time for the holiday shopping spree. Will we see Nexus 9 + HTC + Tegra K1 + Android L this fall? Yeah, it’s looking that way.

MediaTek Labs and LinkIt Platform Launch Targeting IoT and Wearables

MediaTek Labs and LinkIt Platform Launch Targeting IoT and Wearables

Companies such as Motorola, Apple, Nest, and Fitbit have been targeting the Internet of Things (IoT) and wearables market with devices for the past several years. However, if the smartphone revolution was any indication, we are merely at the tip of the iceberg for these devices. Even Apple acknowledged as much by naming the processor inside the Apple Watch the “S1”, clearly planning for future revisions.

Today, hoping to capitalize on this next wave of technology proliferation, MediaTek is formally launching their Labs program for IoT and wearables. This is one of many announcements we will see over the next year as companies look to enter this market.

MediaTek Labs’ goal is to be a central hub for developers to collaborate on everything from side-projects to big business device production. With Labs, MediaTek provides software and hardware development kits (SDKs and HDKs), technical documentation, example code, and discussion forums. MediaTek was a late entry into the smart phone market in 2009/2010 but has since exploded in popularity largely due to very complete reference designs and aggressive pricing. MediaTek aims to reproduce this success, only earlier, for the IoT and wearables space.

When discussing hardware, it’s important to keep in mind there are actual several sub markets. I’ve reproduced a slide and table from MediaTek that does a decent job laying out the differences.

Focus for MediaTek LinkIt and Aster (MT2502) chipset

Multiple apps and functions

Sophisticated UI with more powerful graphics and multimedia features

One thing I do not like about this table is it insinuates these markets are mutually exclusive. While I agree there are indeed hardware and software differences between sub markets, with low enough sleep power and smart enough software, a single device could contain both a high performance applications processor (AP) as well as a low power microcontroller (MCU). In fact, that’s exactly what Intel’s Edison platform and many smart phones do, such as the Moto XNevertheless, hybrid devices are certainly more complicated and there is a lot of success to be had focusing on a single task.

For example, the popular Pebble smart watch and Nest thermostat each contain a simple MCU with no high performance AP.  This is exactly what MediaTek is targeting with their first platform release on labs: LinkIt. LinkIt actually refers to MediaTek’s new MCU operating system, which is launching alongside a new SoC named Aster or MT2502. Additionally, a hardware development kit from partner Seed Studio is available through Labs, as well as a software development kit to aid in firmware development and to help port existing Arduino code.

The core of this kit is of course the new Aster MT2502 SoC. MediaTek feels it is uniquely positioned with an SoC that contains an MCU, Power Management Unit (PMU), Memory, Bluetooth 4.0, and a GSM and GPRS Dual SIM modem (850/900/1800/1900MHz). The total size of the SoC is 5.4×6.2mm. If GPS/GLONASS/BEIDOU or WiFi b/g/n are desired, MediaTek provides compatible external ICs for each.

MediaTek Aster MT2502 SoC
Size 5.4mm x 6.2mm
Package 143-ball, 0.4mm pitch, TFBGA
CPU ARM7 EJ-S 260MHz
Memory 4MB RAM integrated
Storage 4MB Flash integrated
PAN Dual Bluetooth 4.0
WAN GSMS and GPRS dual SIM modem
Power PMU and charger functions
Low power mode and sensor hub function
Multimedia AMR speech codec, HE-AAC music codec, Integrated audio amplifier, JPEG decoder/encoder, MJPEG decoder/encoder, MPEG4 decoder/encoder
Interfaces LCD, VGA camera, I2C, SPI, UART, GPIO, SDIO, USB 1.1, Keypad, Serial Flash, JTAG, ADC, DAC, PWM, FM Radio

Developers eager to get their hands dirty can do so as of today for $79. The LinkIt One development board is available and shipping from Seed Studio. This board combines the Aster MT2502A SoC, MT5931 for WiFi, MT3332 for GPS, audio codec, SD card, many I/O interfaces similar to Arduino, and Arduino shield compatibility.

It will be a while before we see non-prototype designs featuring LinkIt and Aster hit the market, but if MediaTek has its way that will only be the start. MediaTek plans on releasing more SDKs, HDKs, and chips through their Labs website and partners over the next few years. As of this writing MediaTek has already posted a beta SDK and emulator for Android targeting the higher performance IoT and wearable devices. While I am not personally sure just what additional smart devices I need in my life right now, I actually think that gets me more excited about the future than otherwise.

Corsair Gaming K70 RGB Mechanical Keyboard Review

Today is the dawn of a new era for Corsair, as the company has multiple announcements. Corsair is establishing their own gaming brand, announcing the availability of the new RGB keyboards and mice, and they’re also releasing a new software engine for their input devices. We’re focusing mostly on the new RGB keyboards, and Corsair is dropping the “Vengeance” series name with the new keyboards simply use the brand name and model. So how does the newly christened Corsair Gaming K70 RGB keyboard fare? This keyboard probably had more hype than any other keyboard in history, so let’s find out if it can live up to expectations in our full review.
