The phyCORE-AM68x/TDA4x [1] is a SoM (System on Module) featuring TI's
AM68x/TDA4x SoC. It can be used in combination with different carrier
boards. This module can come with different sizes and models for DDR,
eMMC, SPI NOR Flash and various SoCs from the AM68x/TDA4x (J721S2) family.

A reference carrier board design, called phyBOARD-Izar is used for the
phyCORE-AM68x/TDA4x development kit [2].

Supported features:
* Debug UART
* 2x SPI NOR Flash
* eMMC
* 2x Ethernet
* Micro SD card
* I2C EEPROM
* I2C RTC
* 2x I2C GPIO Expander
* LEDs
* USB 5 Gbit/s
* PCIe

For more details see the product pages for the SoM and the
development kit:
