Pocket size Linux single-board computer is $29.95
The PocketBeagle Linux computer - which is just like the BeagleBone Black but small enough to fit in a wallet - is available for $29.95.

A small sized computer, a small price tag, open source…it is all in the pocket with the new Pocketbeagle. This new board from Adafruit is now available and promises a wealth of possibilities to learn, teach or experience.

It has a fully-integrated chip that combines the processor and RAM all on one chip, so it's super small. Despite the compact shape, there's 72 total breakout pads, a microSD card slot for your filesystem and OS, and a native USB connection.

Compared to other single board Linux computers, what differentiates the BeagleBone is that it has multiple I2C, SPI and UART peripherals (many boards only have one of each), built in hardware PWMs, analog inputs, and two separate 200MHz microcontroller system called the PRU that can handle real-time tasks like displaying to RGB matrix displays.

It comes with 72 expansion pin headers, high-speed USB, 8 analog pins, 44 digital I/Os, and plenty of digital interface peripherals. You can also add a USB host connection by wiring a USB A socket to the broken out USB host connections labeled VI, D+, D-, ID and GND. Then plug in any USB Ethernet, Bluetooth, and Wi-Fi device with available Linux drivers.
