The Beagleboard Foundation has released their smallest BeagleBone to date. What can this $25 SBC do?

You've probably heard of BeagleBones and the Beagleboard Foundation by now (check out that link if you're not familiar with them). They make open source SBCs and have an online community much like the Raspberry Pi Foundation.

While Beaglebones don't have as large of a community or market share as Raspberry Pi, their boards are still quite popular because they tend to be more application-focused than Raspberry Pis. For example, there's the general-purpose Beaglebone Black, the sensor-oriented Beaglebone Green, and the Beaglebone Blue for robotics applications.

The newest member of the BeagleBone family is much smaller, but it still packs a punch for certain applications and has a lot of potential for modification with all those pins.

Like its BeagleBone predecessors, the PocketBeagle is geared toward applications like drones, CubeSats, robots, and robotics industrial equipment like 3D printers, CNC mills, and laser cutters. Most news outlets are comparing it to the Raspberry Pi Zero, but I don't find that to be entirely accurate. Like the Raspberry Pi Zero, it has a GUI, it's Linux-based, it stores its operating system in an SD card, and it's powered through a micro USB port (the microUSB on the PocketBeagle doubles as a host/client).

Unlike the Raspberry Pi Zero W, however, the PocketBeagle has no RF module for wireless communications, no standard-sized USB port, and one fewer microUSB port. What the PocketBeagle has that the Pi Zero W is lacking is a lot more pin headers (72 on the PocketBeagle versus 40 on the Pi Zero W). These 72 pin headers each have power and battery I/Os. Of these pins, there are 8 analog inputs, 44 digital I/Os, and "numerous digital interface peripherals."

The other major difference is that the PocketBeagle's processor has a 3D accelerator, which allowed BeagleBone to make this board geared toward navigation and 3D printing applications. The PocketBeagle is available for order now through Mouser, Arrow, and Digi-Key.
