There are several developers working towards this right now! Unfortunately most of these projects are still in the "Crowdfunding" or "Pre-order" stages. One promising board, the "UP-Board" currently on Pre-Order: http://www.up-board.org/ $99 2GB RAM 16GB EMMC memory Intel processor (Compatible with Windows 8.1/10, Unknown if compatible with Linux) ...

A Raspberry Pi might be an option, esp. considering it's low power consumption, as well as low cost. WebGL is somewhat experimental, but HTML or Java would work. The Pi 2 has good specs ($35 gives you 1GB RAM and a quadcore CPU), and additionally it has a large community around it so many things are better documented and better supported. Additionally, ...

To measure the signal integrity all you need is an oscilloscope. Your requirements aren't in the (old) I2C specifications, but need to be found in the data sheets for your particular devices connected to the bus. For sniffing and analyzing the bus I'd recommend a Saleae Logic. (http://www.saleae.com). Later versions can perform analog measurements, too. All ...

PocketChip (http://getchip.com/pages/pocketchip) may satisfy your needs, but may be overkill. It has a very small QWERTY keyboard, a 4.3" screen and a battery, for $50. It is not clear whether the USB output is exposed or not, only the GPIO is mentioned... The other gotcha is that it has not been released yet, and there is no specific launch date for it yet ...

I would recommend the Arduino. Arduino chips are absolutely the way to go! The Arduino MEGA uses the ATmega16U2 chip and meets all of your requirements. It can easily run on USB power or less. Features • High Performance, Low Power AVR® 8-Bit Microcontroller • Advanced RISC Architecture – 125 Powerful Instructions – Most Single Clock Cycle Execution – 32 ...

You might consider looking for a used point of sale system. I've played with PARs, Microses, and Alohas and have never had any trouble with Debian. Even the touchscreens generally work with out of the box installations. Certainly not as fuel efficient as a Pi (though POSes do still use processors designed for efficiency rather than performance), but ...

I assume that you are looking for TV in UK. All TV's I listed below have VESA mount so you can mount them on the wall. If you are looking for cheapest solution I would recommend this TV's (all of them meet your requirements): LG 50LF652V - £537.55 on transparent-uk.com Philips 50PFH5300 - £440.33 on www.lambda-tek.com LG 50LF5800 - £439.08 on www.lambda-...

Atomic Pi, ~$35 on Amazon. Runs an Atom X5 Z3850 CPU (quadcore, with 2GB of RAM, and 16GB SSD), very energy efficient. Good for Linux, not Windows.

You can buy used. For example, This - HP DC7800 Ultra Small Form Factor Desktop Computer (Refurbished) - is an extremely cheap x86 platform that does actually have some upgrade potential. It costs $50, but is more powerful than some SBC options and certainly more configurable. It is the cheapest such machine I am aware of from large suppliers online. You ...

I've successfully written and ran a Qt/QML application (albeit with a simple interface) on a custom baseboard for the CM3 running Raspbian Lite without X. Not through framebuffer but using the VC .sos provided for the Pi. If you used framebuffer on the Pi you likely used Qt without hardware acceleration. Qt has a separate QPA backend using VC libraries ...

A quick search shows you might have some luck with Beaglebone or Beagleboard with regards to emulation. OTOH those boards are cheaper then most JTAG debuggers. I know of three companies manufacturing Cortex-A processors which have openly downloadable documentation: Texas Instruments (theirs are in the Beaglebone) NXP ST Microelectronics

I was wondering how the real systems do start immediately? They don't? A simple Google search reveals, for instance, that Tesla boot time is ways longer than the one of a Raspberry Pi. I'm not even talking about devices other than cars. Most home routers need a minute or two to boot, and where I work, a Xerox machine takes up to ten minutes to boot. In a ...

Have a look at this: https://store.open-electronics.org/index.php?route=offers/salescombopge&page_id=6 Its from a quick Google search. A plus of going with a Pi is having ModemManager (software for controlling modems). Ive seen a working SMS manager connected to ModemManager written in around a hundred lines of Python. Or if you have access to a regex ...

Yes, I was looking for the same requirement last month, I found e-con Systems who make cameras for NVIDIA Jetson TX1. They have a 360degree solution for TX1. I can see that they run 6 MIPI CSI-2 Cameras simultaneously. Please refer : https://www.e-consystems.com/blog/camera/?p=1709

Another possible solution, if you need even less processing power and more cost savings, might be the ALIX.3D2. This is a dev board which supports linux and runs an AMD Geode x86 processor at 500mhz - very low power, very low performance, but also very small and rather inexpensive - though you'll have to source the enclosure and power supply as well, of ...

One solution with which I am familiar is to buy an older thin client such as the HP t5740e WES. This machine is low-power and fairly cheap, but it has your RS-232 and ethernet as required. It also has some other neat perks, like 4gb of internal flash storage (not as fast as a conventional SSD for sustained reads/writes, but should make for a good swap ...

$14.95 will get you this: It has a plug & play Grove connector, so you can easily add on GPS for a further $12. If you can live without GPS, or can solder, then I also recommend LilyGo. They have a slim wristband, like an activity tracker for about $20: and a wristwatch with a larger screen for about $25: All three of these are ESP32 based, so have ...

One important question you need to ask yourself is if you need industrial build quality and long term hardware support, or a research/prototype platform. If you need an industrial PC, I don't have any <100 dollar options for you, but you might spend 100-200 dollars on a Compulab product. I have pretty good experiences with them, the hardware design seems ...

The Arduino is probably one of the best options out there. Another board that you might find interesting is the SimpleLink Wi-FI CC3200 Launchpad. You can program the board via two ways, which are Code Composer Studio (CCS) by TI and Energia (which is basically an Arduino IDE fork). There is a MOD version of this board, but the only major difference is that ...
