Capacitive Touch Panel
The EPC-CM3-070 has a 5-point capacitive touch screen, with a 1024×600 resolution, that offers stable and accurate control over the device and great image clarity. They are also very durable and resistant to environmental contaminants like dust and water. These types of screens work best with either a finger or a stylus with a conductive tip.
Software and OS
The EPC-CM3-070, like other Raspberry Pi® based products, supports the Debian operating system.
Chipsee software engineers have created all the drivers, so every hardware feature is readily available for any standard development tool.
Of course, if your project requires an OS that is not on the list, please contact us, and we’ll make a customized version that suits your needs.
