Introduction
###############

PocketBeagle2 is based on `Texas Instrments AM6232 SoC <https://www.ti.com/product/AM623>`_, it's dual A53 cores can 
provides more than double the performance of the classic PocketBeagle. The new design comes with pre-soldered headers, 
3-pin JST-SH 1.00mm uart debug port, USB-C port, MSPM0L1105, 512MB RAM, LiPo Battery charger, and optional eMMC storage.
