MYIR has launched an HMI touch panel priced at $239 with a 7-inch resistive screen, which can run Linux on TI AM335x, and provides -10 to 70°C support and 4G LTE module. MYIR Linux-based "MY-EVC5100S-HMI" touch screen computer is designed for HMI systems in industrial control, manufacturing, vending, food and beverage, automation and utility applications. MYIR has used this platform to develop a charging display application for electric vehicle charging piles. MY-EVC5100S-HMI (left) and integrated in the electric vehicle charging station (click the picture to enlarge) MY-EVC5100S-HMI is built around Texas Instruments Sitara AM335x SoC, the system provides a single 800MHz Cortex-A8 core. The device may run on MYIR's MCC-AM335X-Y or MCC-AM335X-J modules, which are built on the same energy-efficient TI SoC.
The system is equipped with 256MB or 512MB DDR3 RAM and 256MB to 1GB of NAND flash memory. The microSD slot provides storage expansion. The system’s 7-inch resistive touch screen provides 800 x 480 resolution and 1,000 nits of brightness. There is also a Fast Ethernet port, a USB 2.0 host port, a serial debug port, and an audio jack.
The rugged Phoenix connector also provides other interfaces, including 2x CAN, 2x RS485 and 2x RS232 interfaces, one of which is "reusable with WiFi/BT." There is also an interface for the built-in power failure detection circuit and the optional super capacitor battery module.

Options include 802.11b/g/n and Bluetooth 4.1 BLE modules, and Si4432 RF ISM transceiver modules. The external antenna supports all wireless options. MY-EVC5100S-HMI side panel details (click the image to enlarge) MY-EVC5100S-HMI is further equipped with watchdog, buzzer and RTC. There is a 12V power input, as well as power, reset and start buttons. The rated temperature range of the system is -10 to 70°C.
The Linux stack is based on Linux 3.14 and includes driver interfaces for various I/O and wireless devices. MYIR also provides Qt 4.8.6 GUI with source code and various demonstration examples.
The MY-EVC5100S-HMI touch panel is now "priced by sample", with a unit price of US$239. More information can be found on MYIR's MY-EVC5100S-HMI announcement and product page.
