TOUCH PANEL EA TOUCH240-3 An analog touch panel is available as an accessory. It has a selfadhesive material on its rear side that makes it simply to stuck onto the display. The connection is made by means of a 4-pin flexible cable for a ZIF connector (e.g. EA WF100-04S) with a grid of 1.0 mm. Bending radius is defined with min. 5mm. For optimum readability we recommend that you use a backlight with the display. Interfacing to a µC can be either done via external touch panel controller or directly with a µC that is featured with analogue inputs. How to work with it ? The touch panel is similar to a potentiometer: connecting a voltage of e.g. 3.3V to the pins Top-Bottom makes it possible to read out a voltage on pin Left or Right which is linear to the Y-coordinate of the pressed point. The Xcoordinate will result when the voltage will be supplied to Left-Right and measurement is done at Top or Bottom. The pinout of the connecting cable is shown in the drawing. https://elecena.pl/product/9718250/ea-touch240-3-touch-panel-analog-for-gluing-on 2017-08-06 https://elecena.pl/product/9718250/ea-touch240-3-touch-panel-analog-for-gluing-on 2018-03-06 https://elecena.pl/product/9718250/ea-touch240-3-touch-panel-analog-for-gluing-on 2018-12-17 https://elecena.pl/product/9718250/ea-touch240-3-touch-panel-analog-for-gluing-on 2019-04-09 https://elecena.pl/product/9718250/ea-touch240-3-touch-panel-analog-for-gluing-on 2021-06-08 https://elecena.pl/product/9718250/ea-touch240-3-touch-panel-analog-for-gluing-on 2021-12-23 https://elecena.pl/product/9718250/ea-touch240-3-touch-panel-analog-for-gluing-on 2022-10-14 https://elecena.pl/product/9718250/ea-touch240-3-touch-panel-analog-for-gluing-on 2023-01-06
