Add some jazz & pizazz to your project with a colour touchscreen LCD. This TFT display is big (3.5" diagonal) bright (6 white-LED backlights) and colourful! 480 x 320 pixels with individual RGB pixel control, this has way more resolution than a black and white 128 x 64 display, and double our 2.8" TFT. As a bonus, this display has a resistive touchscreen attached to it already, so you can detect finger presses anywhere on the screen. This display has a controller built into it with RAM buffering so that almost no work is done by the microcontroller. The display can be used in two modes: 8-bit or SPI. For 8-bit mode, you'll need 8 digital data lines and 4 or 5 digital control lines to read and write to the display (12 lines total). SPI mode requires only 5 pins total (SPI data in, data out, clock, select, and d/c) but is slower than 8-bit mode. In addition, 4 pins are required for the touch screen (2 digital, 2 analogue) Of course, we wouldn't just leave you with a datasheet and a "good luck!". Check out our detailed tutorial for wiring, testing and example code! For 8-bit interface fans, we've written a full open-source graphics library that can draw pixels, lines, rectangles, circles, text, and more. For SPI users, we have a library as well, it's separate from the 8-bit library since both versions are heavily optimized. We also have a touch screen library that detects x, y and z (pressure) and example code to demonstrate all of it. Revision History * As of February 10th, 2025 - We've updated the backlight driver as the previous chip was discontinued. * As of December 27, 2022 – we've updated this PCB to use TSSOP instead of SOIC versions of the 74-series level shifters, and to use a TPS61040-based backlight driver instead of FAN5331. We've also used Adafruit Pinguin to make a lovely and legible silkscreen. You may get the new PCB or the older version - both are identical other than the component swaps & fancy silkscreen. Specifications * PCB may come in blue or Adafruit black * 3.5" diagonal LCD TFT display * 320 x 480 resolution, 18-bit (262,000) colour capable - our code uses only 16-bits since it's faster. * 8-bit digital interface, plus 4 or 5 control lines (12 pins minimum) or SPI mode with 4 or 5 SPI data/control lines (4 pins minimum) - not including the touch screen. * 5V compatible! Use with 3.3V or 5V logic such as an Arduino * 3.3V @ 150mA LDO regulator * 6 white LED backlights with DC/DC constant-current boost. You can PWM dim the backlight * 1 x 20 headers for easy breadboarding * 4-wire resistive touchscreen * Screen: 56mm x 85mm x 4mm * PCB: 56mm x 97mm x 2mm * Weight: 52g Resources * Tutorial and Downloads https://elecena.pl/product/22711917/3-5-tft-320-x-480-touchscreen-breakout-board-with-microsd-socket-hxd8357d 2023-03-06 https://elecena.pl/product/22711917/3-5-tft-320-x-480-touchscreen-breakout-board-with-microsd-socket-hxd8357d 2023-12-27 https://elecena.pl/product/22711917/3-5-tft-320-x-480-touchscreen-breakout-board-with-microsd-socket-hxd8357d 2024-09-19 https://elecena.pl/product/22711917/3-5-tft-320-x-480-touchscreen-breakout-board-with-microsd-socket-hxd8357d 2024-11-29 https://elecena.pl/product/22711917/3-5-tft-320-x-480-touchscreen-breakout-board-with-microsd-socket-hxd8357d 2024-11-30 https://elecena.pl/product/22711917/3-5-tft-320-x-480-touchscreen-breakout-board-with-microsd-socket-hxd8357d 2025-04-09 https://elecena.pl/product/22711917/3-5-tft-320-x-480-touchscreen-breakout-board-with-microsd-socket-hxd8357d 2025-11-28 https://elecena.pl/product/22711917/3-5-tft-320-x-480-touchscreen-breakout-board-with-microsd-socket-hxd8357d 2025-11-29
