Som-am437x-pm Basic Evaluation Kit (model: sbc-ph8800)

summary: 

Som-am437x-pm single board computer (model: sbc-ph8800, hereinafter referred to as sbc-ph8800) is a basic development tool based on the core board som-am437x-pm (model: som-ph8800, hereinafter referred to as som-ph8800). It adopts the inbert custom ph180 standard form factor and signal definition. It is composed of the compact CPU core board module som-am437x-pm (Part No: som-ph8800) and the simplified bottom board Bb-sph1800. This kind of core system and the bottom extension separate structure design makes sbc-ph8800 not only be a development platform, but also can be directly used as the core functional components of terminal products, so as to shorten the customer R & D cycle, make electronic products put into production quickly and accelerate the time to market. Sbc-ph8800 provides a lot of peripheral resources, such as Gigabit Ethernet interface, USB interface, one channel 24bit LCD interface, one channel HDMI, TF storage expansion, RS232, can, RS485, etc. At the same time, sbc-

ph8800 has 40pin dual in-line pin, which can expand I2C, I2S, UART, MMC, Gigabit Ethernet and other signals.
