(Heaven Zhuhai Branch rudder Note: Do not with me count punctuation oh), two words "very expensive!", three words "very expensive!" ", four words" a catty cut cake! ", five words" a tea egg! ". You see, like Raspberry Pi and Arduino these just offer a limited set of features and simple extensions such as GSM shield and so on can sell to 80 American knives. For the "10 Jin Cut Cake" You may not be anything, but for us only 10 of the wealth value of ice cream is not the same, because compared to a full function of the smartphone only sell a 30 U.S. knife, the price can die a person. So why not turn your smartphone motherboard, which is worth a few ice cream, into an IoT platform for embedded project development? A few ice cream can be changed to a powerful function, why not?

FAQ

• can I put a sensor or led on it ? Most of the phones have some gpio pins that let you mount some extra electronic originals onto their motherboard, such as LED lights. We have previously published a blog post describing how to attach an led to the Geeksphone Keon Firefox phone and control it.
• this stuff can run native code no ? You can use the Android ndk/toolchain to compile any binary code for the ARM architecture for the motherboard, and you can invoke the binary code using the Mozos.exec API. Please click to view examples.
• brother, does this thing save electricity ? It depends on how you use your phone. In general, the idle 2G network consumes approximately 5-10ma per hour of power. You can try using an electronic USB ammeter to check the power consumption. For more information, see here.
• does this guy want a battery ? Demon! Have you ever seen a mobile phone that can run most applications (boot, wifi network detection, etc.) without a battery? Of course the battery. Is it not easy to pick up a battery? It's not easy to weld a battery behind a few of your ice cream motherboards.
• introduce a debugger with a chant ? Use Webide, which is part of the Firefox development tool, designed to connect your device for debugging.
