University of California San Diego

4.2 (153 ratings) | 12K Students Enrolled

Do you want to develop skills to prototype mobile-enabled products using state-of-the-art technologies? In this course you will build a hardware and software development environment to guide your journey through the Internet of Things specialization courses. We will use the DragonBoard™ 410c single board computer (SBC). This is the first in a series of courses where you will learn both the theory and get the hands-on development practice needed to prototype Internet of Things products. This course is suitable for a broad range of learners. This course is for you if: • You want to develop hands-on experience with mobile technologies and the Internet • You want to pivot your career towards the design and development of Internet of Things enabled products • You are an entrepreneur, innovator or member of a DIY community Learning Goals: After completing this course, you will be able to: 1. Configure at least one integrated development environment (IDE) for developing software. 2. Make use of git, adb and fastboot to flash multiple OS and repair bricked boards. 3. Install Android 5.1 (Lollipop) and Linux based on Ubuntu. 4. Create, compile and run a Hello World program. 5. Describe the DragonBoard™ 410c peripherals, I/O expansion capabilities, Compute (CPU and Graphics) capabilities, and Connectivity capabilities.

Great content, the guys although young, nailed the subject. Hope the next course is as good as this.

Very good course, it has a decent mix of theory and practice to dive into the board's specifics.

From the lesson

Board Bring up

The new and exciting DragonBoard™ 410c is now available! In this module you will get introduced to the new all-in-one board, get an overview of all its amazing features and find out how you can get one yourself. We will then walk you through the registration process, and how to get your board started up for the first time! By the end of this module you will know enough about the DragonBoard™ 410c to begin using it for the fun projects that are to come later in this course and in the rest of the courses in the Internet of Things specialization.

Transcript

I think it's time to talk about the board and all of the components on the board.

Kinda getting you familiarized like we promised earlier.

With everything on there.

>> We want to get chance you just kinda point out where everything is on the board

so you can see where it's at and get a kind of feel for it.

>> Alright.

>> First off, we have the Qualcomm Snapdragon 410 processor.

This is the shining star of the Dragon board because it's the brain of the board.

>> I like what you did there.

>> I got really excited because I've used other boards in the past and there's so

many problems with having lots of lag and glitching and

trying to move around and it kind of jumps around awkwardly.

But we don't have any kinds of those problems using this board so

it's been really exciting.

>> Oh, so you have to see it for yourself.

>> [LAUGH] >> But there is one gigabyte of RAM

on board, and there's also a little slot to be able to put in

a micro SD card and so there's a lot of options with that.

>> I'd actually like to talk about that real quick.

We have experience with other boards,

like the SD card slot can't be used for anything.

You're either running your operating system off it, you're running boot disks

off of it, you're running a boot file off of it or an image.

With this board, you can not only boot an operating system or flash an operating

system onto the board, you can also use the micro SD card as extra storage space.

At least a few of the boards that I've had experience with you can't do that.

So that's a really cool feature about the micro SD card slot.

>> Yeah, and also one of the most exciting things for

me was that if you look you can see that there is wireless

internet, GPS and Bluetooth all built into the board, and

I have never seen another one that had all three of them already pre-installed and

that comes with it so it's been really exciting.

Again the Micro SD slot and there's different dip switches so

you control how to boot from the card or not, and

so you can use that to be able to install different operating systems on the board.

There are two USB ports.

We haven't found a much need to have more than that because again,

no extra dongles to plug in WiFi, no extra dongles to plug in Bluetooth,

don't have to deal with that, just got a mouse and a keyboard and

also keyboards available that have a little touch pad included so

it hasn't been a problem at all.

Now, there is a micro USB port.

This is to connect to a computer.

It does not work at the same time as the mouse and the keyboard, but then,

you don't need the mouse and the keyboard if you're connected to a computer.

So, again, no problem there.

Yeah.

>> Another cool thing about that is

you have basically a PC host to manipulate aspects of the board.

So- >> Connect through a terminal.

>> Connect through a terminal.

Do all sorts of cool things through there.

In fact that's how you're gonna be importing your applications from Android

studio onto the board.

Yeah. >> Yeah I guess that's important to note

that if you're more Android you'll probably use the micro USB and

if you're more Ubuntu you'd use the USB slots.

>> Yeah, so as you can see up there, number 7,

also the 40 pin expansion header which is the low speed expansion header.

That's where you're gonna find all of the GPIO interfaces,

especially the ones that we're gonna be using for this course, and

we're gonna talk to you way more in detail about all that later on.

>> Yeah, I take it back.

This is one of the most exciting things in the course.

[LAUGH] >> Yeah.

>> There's so many things.

>> For this course, this is gonna be one of the things we're gonna be using

the most, at least for course three.

But, yeah, definitely.

We have a 16 pin analog expansion header,

which is located right next to the 40 pin expansion header.

On this header you have access to audio, you have access to

microphone jacks, so essentially you're able to solder in a 3.5,

for example, 3.5 millimeter audio jack and

plug in some speakers or solder on a jack for a microphone.

There's lots of other interesting things on there.

We won't go too much into detail in this course but just so

you know it is there and there's plenty of documentation on this header.

We have a 60-pin, high speed header which is gonna be used for

a lot of other things that we won't be covering in this course.

Possibly in later courses, but just so you know it's there and

there again is a lot of documentation on this header.

You have the power button right there, you can see the power symbol there.

Pretty straightforward, but you're gonna be using that mostly for Android,

powering off your board on Android.

You most likely won't be touching it when you're running the Ubuntu.

>> Yeah there's shut down menus on Ubuntu.

>> When you picture your cell phone, you picture, you have your sleep/power button,

you have your volume buttons, which are located right next to the power button and

that's mainly what that's gonna be for on Android.

The minus button is used later on for

booting into fast boot, but you'll be taught how to do that later.

The DC barrel jack, basically how you power your board.

Pretty self explanatory.

You're gonna need to stick between a 6.5 volt and

a 18 volt DC power supply, or

power adapter and two amps.

So you can find all that information in the spec sheets for the board.

But you definitely want to make sure you look at that so

that you don't burn out your board by plugging in too high of a voltage.

>> Yeah. >> So stick between 6.5 and 18.

>> The nice thing here, though, is it has a lot higher voltage than most

boards customly have, cuz if I took an 18 volt adapter and

plugged it into something else, it would probably burn it out.

>> Oh yeah, no, we've actually done that.

So, yeah [LAUGH].

Yeah. >> [LAUGH] Well,

this one's a bit safer so [LAUGH].

>> Yeah, and definitely being able to put higher voltages in there.

>> Plus it's nice cuz then you get a high voltage

power rail out of the 40 pin expansion header which can be very useful if you're

running certain things like- >> Oh yeah,

we're gonna actually talk about that.

So sometimes you might need to run a really high voltage to power

a certain device.

This board's already got that, so no need for batteries or extra adapters.

>> Yeah. For example, powering a motor.

>> Oh, yeah.

>> Yeah.

>> Yeah, and then last but not least, the HDMI port.

It's how you're gonna see everything right?

So, a full sized HDMI, two HDMI, really cool.

So, yeah, there's your board, at least, some of the main components.

I'd recommend looking at it and kind of getting familiar with it.
