The PocketBeagle is an ultra-compact, open-source Linux single-board computer powered by the AM3358 processor running at 1 GHz. Using a system-in-package design with integrated processor and RAM on a single chip, it delivers full BeagleBone functionality in a pocket-sized form factor.

Despite its compact size, the PocketBeagle breaks out 72 expansion pins with extensive I/O: multiple I2C, SPI, and UART peripherals, hardware PWMs, 8 analogue inputs, and 44 digital I/Os. It also includes two 200 MHz PRU (Programmable Real-time Unit) microcontrollers for handling time-critical tasks such as driving RGB matrix displays or NeoPixels.
