Tue Jun 25 11:54:02 PDT 2024
The phyCORE-AM62Ax [1] is a SoM (System on Module) featuring TI's AM62Ax 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 AM62Ax family.
A development Kit, called phyBOARD-Lyra [2] is used as a carrier board
reference design with a mapper board being used to allow the phyCORE-AM62Ax
to fit the phyBOARD-Lyra.
Supported features:
* Debug UART
* SPI NOR Flash
* eMMC
* 2x Ethernet
* Micro SD card
* I2C EEPROM
* I2C RTC
* GPIO Expander
* LEDs
* USB
* HDMI
* USB-C
* Audio
