Arduino UNO Q gets a 10.1-inch touch display with integrated speakers, audio jacks, camera connectors

Waveshare UNO-Q-DSI-TOUCH-10.1A is a 10.1-inch touchscreen display designed for the Arduino UNO Q single board computer. The Arduino UNO Q exposes its MIPI DSI interface through the 60-pin JMEDIA and JMISC headers, and for all practical purposes, you normally need a board like the Arduino UNO Media Carrier to make use of it. The UNO-Q-DSI-TOUCH-10.1A display solves that by integrating the headers so users can simply insert the Arduino UNO Q into it without an additional adapter board or special wiring. Waveshare UNO-Q-DSI-TOUCH-10.1A specifications: Screen Size – 10.1-inch Panel type – IPS panel Native Resolution – 1280 x 800 Refresh Rate – 60 Hz Colors – 16.7 millions Viewing Angle – 178° Brightness – 300 cd/m² Contrast Ratio – 800:1 Response Time – 35 ms Multi-touch support Capacitive multi-touch (we’re told the actual number of touch points somehow depends on the software system) Interface I2C Tempered glass, optical bonding Camera […]
