Biemme Italia is proud to present a new touch panel that support Android 5.1 technologies. This powerful board comes with a capacitive 4.3″ touch screen that is well suited to interact with industrial and home automation systems. It supports many communication interfaces such as WiFi,Ethernet, Bluetooth,RS485,USB 2.0 and it has a special GPIO header. Ingress protection code IP54,  stainless steel frontal frame and stainless steel rear cover.
In order to leverage the flexibility of the Android OS, the board has a native modus RTU library for Android that is able to communicate with every device through RS485.

The mirror stainless steel frontal frame encloses a capacitive display 4.3″ with resolution 480×800 with an excellent brightness.

This Ltouch43 board features a Samsung cortex A53 processor 64 bit Octa Core with frequency from 400MHz to 1.4GHz

The Ltouch43 has a RAM memory 2GB 32bit DDR3 and storage eMMC of 16GB and more external storage up to 128GB.

The eMMC architecture integrating the flash memory controller in the same package simplifies the application interface design and frees the host processor from low-level flash memory management. This benefits product developers by simplifying the non-volatile memory interface design and qualification process – resulting in a reduction in time-to-market as well as facilitating support for future flash device offerings. In other words, eMMC memory hides the complexities of flash memory technology in a convenient “plug-and-play” package. Obviously, this reduces time and effort for developers.
Secondly, eMMC eliminates the need to develop interface software for all types of NAND memory by integrating the embedded controller into the memory chip and providing an easy-to-use memory solutions package for high-speed data transmissions by devices


RS485 and new Library

Full optoisolated RS485 and through a convenient switch it is possible to configure the polarization of the 485 line by inserting or excluding the end-of-line resistance The customers that need specific customization on top of our base package, can use the usual frameworks for Android app developing, for instance Eclipse or Android Studio. The device supports Android NDK, for native programming. The Android kernel is already configured for working with serial ports, without any constraints. The product will comes with a free Android modbus library that can be used to communicate with any commercial products such as PLC, I/O modules, temperature controllers and in general with any device that support the modbus protocol through rs485.

4 Relay on “board

on board there are 4 relays with exchange contact that can be edited with the library. Simple to connect thanks to the removable terminals.

Power Supply voltage recognition

24 Vdc power supply, the hardware architecture recognizes the supply voltage when there is a difference of 20% Ltouch43 and turns off
