PocketBeagle Photos and Graphics

23 Feb 2018

I finally purchased a couple of PocketBeagles, I knew they would be small, but it is still amazing to see it close-up!

image

It is very thin too, it measured 4.60mm (the highest point is the surface of the Octavo module).

image

For connections, I purchased 2x9way total 18-way header pins2x9way total 18-way header pins because these are cheaper than 2x18way. A total of four of these are needed to fully connect to the PocketBeagle, although that might not be necessary for all projects. Note that the header pins are connected to the underside of the PocketBeagle, not to the top side like the larger BeagleBone Black. The pins won't fit on the top side, because the Octavo module hits the plastic surround of the header pins. It seems to make sense, that the PocketBeagle would be plugged on top of a larger board.

 

The very helpful silkscreen shows the pin descriptions on the underside:

Here are some graphics of the top and bottom side, perhaps useful for documenting projects:

    Nice. What have you got planned for them?

    Hi Brian, I'm hoping to develop them as a kind of test tool. Still only a half-thought out idea : )

    That is small.! No I don't need one, so I'm resisting

    It is right, I think the same. Then the undoubted advantage of the beagle is the availability of manage DSP ideal for audio and some other embedded applications. But also, in this case, I have not experienced the new audio features of the PI 3B+

     

    Anyway, if you are interested you can take a look at the project I have developed with NodeJS on the Beaglebone interfaced with other IoT devices at the following links on GitHub:

    Found a photo I took of the sensor on my hard drive..

    It's tiny : )

    Hi Enrico,

     

    For me there's a few benefits, but as you say sometimes it's easier to use the Pi.

    Apart from the SoC differences (PRU etc) which sometimes are not needed, the reason I used the PocketBeagle was to make the transition from a prototype to a custom PCB, because the CAD files for PocketBeagle are available, so it's an easy way to get Linux onto a custom board (Pi compute module didn't suit my particular scenario), i.e. take the PocketBeagle CAD files, delete the headers, and add custom circuitry instead.

    Also the PocketBeagle tiny size could be useful for handheld projects (and also can be powered/charge a LiPo like the larger BBB as I understand).

    On the other hand a lot of things are very mature in Raspbian, so that can be quicker to work with sometimes.

    I have never approached the small version of the BB but the bigger. Frankly, I continue having problems to imagine something that can be done without less effort on the Beagle than on the Raspi. Instead, I have used one as an IoT server to secure a network of sensors, and was perfect for this use.
