BeagleBoard.org BeagleBadge is a compact, affordable open source
hardware single board computer based on the Texas Instruments AM62L3
SoC designed for IoT and embedded applications with low power
consumption. Expansion is provided over open standards based headers
including QWIIC and GPIO interfaces.
