The MYD-Y6ULX-HMI Development Board is specially designed for MYIR’s MYD-Y6ULX-CHMI Display Panel for Human Machine Interface (HMI) applications. It is powered by MYIR’s MYC-Y6ULX CPU Module which is a compact System-on-Module (SoM) integrated with 528MHz NXP i.MX 6UL / 6ULL ARM Cortext-A7 processor, 256MB DDR3, 256MB Nand Flash and Ethernet PHY.


In addition to the core components provided by the MYC-Y6ULX core board, the MYD-Y6ULX-HMI has extended multiple peripheral interfaces like RS232, RS485, USB Host/Device, 10/100Mbps Ethernet and TF card to its base board to allow communications with other devices. It also features a Camera interface and supports 16-bit LCD & 4-wire resistive or capacitive touch screen driven directly from the board circuit. The board provides two 2.0mm pitch 2*20-pin headers for IO extension. User can customize their own IO boards to connect with the MYD-Y6ULX-HMI to further explore more functions. MYIR offers an IO board MYB-Y6ULX-HMI-4GEXP as an option for users which has extended Ethernet, WiFi & BT, USB based 4G LTE Module interface, Audio and GPIOs. A 7-inch LCD with capacitive touch screen is also available as an add-on option, thus making a complete solution for HMI applications.


The MYD-Y6ULX-HMI is preloaded with Linux OS. MYIR has provided plenty of resources including kernel and drivers in source code, application examples and an MEasyHMI QT demo for developers to start their development rapidly.
