1. Introduction
1.1 Hardware Overview:
The WEGA Board for phyCORE-AM335x is a low-cost, feature-rich software development platform
supporting the TI AM335x processor families. At the core of the phyBOARD-WEGA-AM335x is the
PCL-051/phyCORE-AM335x System On Module (SOM) in a direct solder form factor, containing the
AM335x processor, SDRAM, NAND Flash, power regulation, supervision, transceivers and other core
functions required to support the phyBOARD-WEGA-AM335x. Surrounding the SOM is the PBA-CD-
02/ phyBOARD-WEGA-AM335x Carrier, adding power input, buttons, connectors, signal breakout
amongst other features.
The PCL-051 System On Module is a connector-less, BGA style variant of the PCM-051/phyCORE-
AM335x SOM. Unlike traditional PHYTEC SOM products that support high density connectors, the PCL-
051 SOM is directly soldered down to its Carrier Board using PHYTEC's Direct Solder Connect
technology. This solution offers an ultra-low cost Single Board Computer for the AM335x processor,
while maintaining most of the advantages of the SOM concept.
Adding the phyCORE-AM335x SOM into your own design is as simple as ordering the connectored
version (PCM-051) and making use of our phyBOARD-WEGA-AM335x Carrier Board (PBA-CD-02), or
RDK Carrier Board (PCM-953) reference schematics. A summary of the phyBOARD-WEGA-AM335x
features, along with a block diagram are presented below.
