The Lascar Electronics SGD 43-A Programmable panel meter is a 4.3 in. capacitive touch display designed for use with PanelPilotACE Design Studio, a free drag and drop style software package for rapid development of advanced user interfaces and panel meters. The SGD43A's low-profile display features a 4.3 in. capacitive touchscreen and a Cortex ARM 9 processor running embedded Linux. The display for the SGD 43-A can be powered from either USB or a 5V to 30V DC supply. This unit also offers users a wealth of hardware interfaces which include four 16 bit bi-polar analog inputs (to a maximum of +/-40V DC), eight digital input/output pins, two alarm outputs (maximum current sink 10 mA) and four PWM outputs. The SGD43A also includes the free PanelPilotACE Design Studio Software. The design software provides several building blocks which allow users to drag and drop elements onto the screen to quickly create advanced user interfaces. This programmable panel meter allows users to build up multi-screen interfaces without needing to write a line of code. Users can build background images, text elements, analog style meters, touchscreen navigation elements, and even complex logic statements. There is a library of pre-defined elements such as meters, buttons, and switches, and users can create their own content by combining elements or importing graphics in a few formats (including jpg, png, tif, bmp, and gif). The SGD43A's software includes support for transparency and multiple layers.
