Bedeck your Feather project with a beautiful Adafruit TFT FeatherWing, 3.5″ 480×320 Capacitive Touchscreen. This TFT display is 3.5″ diagonal with a bright white-LED backlight and a built-in microSD card socket. You get a massive 480×320 pixels with individual 16-bit color pixel control. This display comes with a multi-touch capacitive touchscreen to detect up to 5 finger presses anywhere on the screen.

The Adafruit 3.5″ Capacitive Touch TFT FeatherWing guide has everything you need to get started with using this FeatherWing. There’s pages for overview, pinouts, CircuitPython, Arduino and resources for download.

The Adafruit USB Host FeatherWing makes it easy to add USB Host support, especially now that TinyUSB supports it in the Arduino library as a ‘native’ interface for host support. This Wing uses the MAX3421E – a tried and true USB Host chip. It uses SPI plus an IRQ pin to send data to just about any USB device.

Spice up your Feather project with a beautiful 2.4″ touchscreen display shield with built in microSD card socket. This TFT display is 2.4″ diagonal with a bright 4 white-LED backlight. You get 240×320 pixels with individual 16-bit color pixel control. It has way more resolution than a black and white 128×64 display. As a bonus, this display comes with a resistive touchscreen attached to it already, so you can detect finger presses anywhere on.

The Adafruit 2.4″ TFT FeatherWing guide has been updated for rev B of the board. As of Oct. 11, 2023, we’ve updated this hardware to use the TSC2007 instead of the discontinued STMPE811 touchscreen controller. The screen and micro SD card are the same but any touchscreen code will need to be updated to use our Arduino or CircuitPython library. We’ve also updated the reset button to be right-angle and added a STEMMA QT port. Lastly, we’ve also updated it with Adafruit Pinguin to make a lovely and legible silkscreen. We have a new Pinouts page, new Arduino example, new CircuitPython example and updated resources on the Downloads page.

[Andy Geppert] sends in his incredibly clever interactive core memory shield. 

In a great display of one hacker’s work being the base for another’s, [Andy] started out with [Jussi Kilpelainen]’s core memory shield for Arduino.  As he was playing with the shield he had a desire to “see” the core memory flipping and got the idea to add an LED matrix aligned behind the individual cores.

The first iteration worked, but it only showed the state that the Arduino believed the core memory to be in. What he really wanted was a live read on the actual state. He realized that an Adafruit Featherwing 8×8 matrix display also fits behind the core memory. Now the LEDs update based on the read state of the core memory. This allows him to flip the individual bits with a magnetic stylus and see the result. Very cool.

You can see a video of it working after the break.
