The MYD-AM437X 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-AM437X development board is using the MYC-AM437X CPU Module 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-AM437X CPU Module is mounted onto the MYD-AM437X base board through two 0.8mm pitch 2*50-pin board-to-board connectors. In addition to those functions provided by the CPU Module, 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.

MYD-C437X Development Board

The MYD-AM437X board series have four models with different AM437x processors. They are sharing the same pin-out with software fully compatible. And the minor differences are mainly from the processors features.

TI AM437x Devices

The MYD-C437X board is able to run Linux OS. It is delivered with some necessary cable accessories and a product disk containing Linux 3.12.10 software packages and detailed documents. MYIR also offers optional 4.3- and 7-inch LCD module (with touch screen), USB based Wi-Fi and Camera modules and BUS based Camera modules for the MYD-C437X board. The complete platform provides a quick AM437x starter kit for users when getting the goods out-of-the-box right away.
