MYD-C437X-V2 Development Board
MYD-C437X-V2 Development Board
The MYD-C437X-V2 Development Board is a complete evaluation platform for Texas Instruments (TI) Sitara AM437x family (AM4376, AM4377, AM4378 and AM4379 ) of ARM Cortex-A9 Microprocessors (MPUs) with optional 3D graphics acceleration and a quad-core Programmable Real-time Unit (PRU) as well as dual camera support. Typical applications are patient monitoring, navigation equipment, industrial automation, portable data terminals, bar code scanners, point of service, portable mobile radios, test and measurement and more others.
The MYD-C437X-V2 development board is using the MYC-C437X-V2 SOM as the core controller board which integrates the core components including the AM437x processor, 512MB DDR3, 4GB eMMC, 32KB EEPROM, Gigabit PHY and PMIC (TPS65218). The MYC-C437X-V2 is mounted onto the MYD-C437X-V2 base board through two 0.8mm pitch 2*50-pin board-to-board connectors. In addition to those functions provided by the SOM, the base board has extended a rich set of peripherals through headers and connectors from the SOM and some extended controller chips including two serial ports, four USB Host ports, one USB Device port, dual Gigabit Ethernet ports, one CAN, one RS485, two camera interfaces, one Micro SD, HDMI, LCD, Touch screen and more others.
