The MYD-YM62X development board is a versatile testing and evaluation platform for TI AM623 and TI AM625 microprocessors which among the TI Sitara AM62x MPU family and feature up to 1.4GHz Quad ARM Cortex-A53 and 400MHz Cortex-M4F cores, dual-display support and 3D GPU (only for AM625) graphics acceleration, along with an extensive set of peripherals.

The MYD-YM62X development board is built around the MYC-YM62X SOM and has explored many features of the AM62x SoC through the 1.0 mm pitch 164-pin Castellated-Hole and 58-pin LGA Expansion Interfaces. It has rich communication interfaces including dual RS485, dual CAN, dual Gigabit Ethernet, dual USB Hos, one OTG, one USB based 5G/4G module interface, one WiFi/BT module and one GPMC external memory bus. It also has advanced multi-media capabilities to support dual LVDS display, audio and camera as well as HDMI display support via a RGB conversion chip. With the excellent performance of AM62x, the MYD-YM62X can be used for various industrial and display applications. The board is preloaded with Linux image and provided with complete development package. The MY-CAM003M MIPI Camera Module and MY-LVDS070C LCD Module can be used as options for the MYD-YM62X board which allows customers to acquire better development experience.
