It isn't enough to publish schematics, board designs and BoMs under an Open Source license. It must be feasible for an individual to make the board themselves, using less than a couple of hundred dollars/GBP/Euros/equivalent of equipment, preferably less than $100.</p> <p>It leaves me feeling sad. </p> <p>I have always trusted the Arduino team to maintain the spirit and possibility of DIY-able Open Source hardware. IMHO, the ability for normal people to be producers of hardware, and not just consumers, is essential. Otherwise we are just unpaid design-drones for companies with the capital to make boards in economic quantities.</p> <p>The Arduino Yún seemed to lose it. AFAICT it is "Dual Row MicroLeadFrame ©" which would be hard to make.<br /> Worse this: <a href="http://wiki.openwrt.org/toh/tp-link/tl-wr703n/ar9331_pinout#ethernet.interface" rel="nofollow">http://wiki.openwrt.org/toh/tp-link/tl-wr703n/ar9331_pinout#ethernet.interface</a><br /> says the pin-out isn't even publicly available from the manufacturer!</p> <p>The Intel-duino ball-grid package is even further away from anything I could make :-(</p> <p>IMHO another bad day for Open Source hardware. </p> http://forums.leaflabs.com/topic.php?id=39294#post-60436 Thu, 03 Oct 2013 12:30:28 +0000 ala42 60436@http://forums.leaflabs.com/ <p>I/O is made with external chips, e.g. a SPI AD7298 12-bit A/D converter and a I2C CY8C9540A 40-bit port extender.

So it'll look like a 'real' Arduino board, though it is far, far away architecturally. (I am assuming the IDE is using gcc for x86. I am not assuming Intel has implemented an AVR or ARM emulator, which would be genuinely amusing if they had :-)</p> <p>It also looks like Intel have jumped through the essential hoops to be Arduino hardware compatible. The diagram shows the board has ADC and PWM chips (external to the processor SoC).</p> <p>Some of the documentation reads like it is 'bare metal' with no Linux or OS mentioned.</p> <p>Edit: I had a look at Intels's FAQ: <a href="http://www.intel.com/support/galileo/faq.htm" rel="nofollow">http://www.intel.com/support/galileo/faq.htm</a><br /> and it says that the board has a small Linux on-board:<br /> " Intel® Galileo runs Linux* out of the box. It comes in two flavors; the default is a small Linux. If you add an SD card to your kit, you can add a more fully-featured Linux."</p> <p>It has quite a lot of storage:<br /> - 8 MByte Legacy SPI Flash<br /> - 512 KByte embedded SRAM<br /> - 256 MByte DRAM<br /> - micro SD<br /> - USB storage<br /> - 11 KByte EEPROM</p> <p>8MB would be a big Arduino program.</p> <p>It sounds quite power hungry: "... recommended output rating of the power adapter is 5V at up to 3Amp." but that might be for the power it can supply to user electronics. It doesn't run off USB power.</p> <p>Intel must be worried to go to this much effort. I imagine in Intel budget terms, it is a small effort. However, I can imagine their legal department alone is costing more than a kickstarter project to do a similar project :-)</p> <p>I wonder what price Intel will sell the chips at for anyone wanting to make their own board?<br /> Might they absorb a loss for a while hoping to get lock-in?</p> <p>I guess IBM will need to follow up with the 'duino-PowerPC, or a Raspberry-PiBM?</p> <p>(Full disclosure: I am not a member of Leafabs staff.
