The Adafruit Feather ecosystem is so rich with hardware diversity, we wanted to share them, one each day. Today is the Adafruit 14-Segment Alphanumeric LED FeatherWing – STEMMA QT / Qwiic!
Display, elegantly, 012345678 or 9! Gaze, hypnotized, at ABCDEFGHIJKLM – well it can display the whole alphabet. You get the point.
A Feather board without ambition is a Feather board without FeatherWings! This is the Adafruit 0.54″ 4-Digit 14-Segment Display FeatherWing! This 14-segment FeatherWing backpack makes it really easy to add a bright alphanumeric display that shows letters and numbers in a beautiful hue. It’s super bright and designed for viewing from distances up to 23 feet (7 meters) away.
Works with any and all Feathers!
14-Segment Matrices like these are ‘multiplexed’ – so to control all the fourteen-segment LEDs you need 18 pins. That’s a lot of pins, and there are driver chips like the MAX7219 that can control a matrix for you but there’s a lot of wiring to set up, and they take up a ton of space. Wouldn’t it be awesome if you could control a matrix without tons of wiring? That’s where these Alphanumeric LED Matrix FeatherWings come in, they make it really easy to add a 4-digit alphanumeric display with decimal points.
The LEDs themselves do not connect to the Feather. Instead, a matrix driver chip (HT16K33) does the multiplexing for you. The Feather simply sends i2c commands to the chip to tell it what LEDs to light up and it is handled for you. This takes a lot of the work and pin-requirements off the Feather. Since it uses only I2C for control, it works with any Feather and can share the I2C pins for other sensors or displays.
This product kit comes with:
A bit of soldering is required to attach the matrix onto the FeatherWing but its very easy to do and only takes about 5 minutes! Note: Feather board and 14-segment display are not included, but we have lots available in the shop.
Of course, in classic Adafruit fashion, we also have a detailed tutorial showing you how to solder, wire and control the display. We even wrote a very nice library for the backpacks in both Arduino & CircuitPython so you can get running in under half an hour, displaying letters or numbers on the 14-segment. If you’ve been eyeing matrix displays but hesitated because of the complexity, this is the solution you’ve been looking for.
USEThe 14-Segment Alpha-numeric LED FeatherWing Guide provides details and use examples.

This is CircuitPython 9.2.0-beta.1, a beta release for 9.2.0. It has known bugs that will be fixed before the final release of 9.2.0.
WARNING for nRF52 boards only: If your board has an nRF52 UF2 bootloader whose version is before 0.6.1, you will not be able to load CircuitPython 8.2.0 and later, due to increased size of the firmware. See these instructions for updating your bootloader.
Highlights of this releaseFirmware downloads are available from the downloads page on circuitpython.org. The site makes it easy to select the correct file and language for your board.
InstallationTo install follow the instructions in the Welcome to CircuitPython! guide. To install the latest libraries, see this page in that guide.
Try the latest version of the Mu editor for creating and editing your CircuitPython programs and for easy access to the CircuitPython serial connection (the REPL).
DocumentationDocumentation is available in readthedocs.io.
Port statusCircuitPython has a number of “ports” that are the core implementations for different microcontroller families. Stability varies on a per-port basis. As of this release, these ports are consider stable (but see Known Issues below):
These ports are considered alpha and will have bugs and missing functionality:

★This week’s EYE ON NPI is loud and proud – it’s the Diodes Incorporated PAM8019E Class-D Audio Amplifier and Headphone Driver a combo audio amplifier that will add high quality analog audio output to your next design without breaking the bank.
We’ve stocked and used the PAM series of audio amplifiers for over a decade, one of our best sellers is the PAM8302 breakout which is a monophonic class D amp for basic projects. Things we like about it: its very inexpensive, it’s rock solid, 3~5V power, hard to ‘pop’ and can drive 4~8 ohm output. But it’s only one channel and we often get asked if we can stock a stereo Class D. Also, it’s pretty common for us to get requests for headphone drivers. The PAM8019E can do both, and has a lot of nice little details.
First up, this is an analog in/out amplifier – no PDM or I2S or TDM. So this is good for either all-analog setups or when you have already converted your digital audio to ‘line level’, about 1Vpp. Since it’s stereo out, there’s also stereo input: don’t worry about DC bias because you can couple in with 1uF and it will internally bias to half-VDD. Unlike the PAM8302, this isn’t differential input, reference is ground. You can use either the Headphone amp or Speaker amp, but not both: the selection is done with with a digital input pin which will do a smooth pop-free hand off.
For the outputs, there’s the stereo Class D outputs. These come as two tied-load bridges which means you can just tie the two sides of each speaker to positive/negative without any capacitors. Class D is an efficient amplification architecture and if done at a high enough frequency – in this case around 400KHz – the inductive load of the speaker acts as a filter so no separate RLC is required. For EMI purposes, the datasheet recommends a simple 100MHz 600ohm ferrite bead plus 1uF capacitor just to reduce the sharp square waves.
For headphone, the chip uses a Class AB, these are going to give cleaner output because there’s no intermediate PWM stage: speakers tend not to be good enough to notice the hiss added from Class D, but headphones are much more sensitive. Also, at the ~50mW output we’re talking about, there’s not a lot of benefit to optimizing power. Since headphones are by design ‘single ended’, you will need 220uF caps on the output for high-pass filtering. Some modern audio amps have a ‘floating’ ground generated to sink the current for cap-less output but these tend to be more expensive and also wouldn’t be compatible with line-level inputs.
Some nice details we like to see in an amp, especially one this affordable: spread-spectrum so the high frequency PWM isn’t centered on one spike, undervoltage-lockout, short-circuit on all outputs, pop-free, non-clip power limiting and separate not-in-line audio level selection. The last one is particularly nice because on the PAM8302 we have to put an analog rheostat in-line with the input pins to reduce the gain from 15x down to 1x or 2x. This would require a stereo pot, which can get scratchy and fail over time.
On the PAM8019E, the gain is set with a DC voltage which means you can set it with a potentiometer or a DAC output, and you don’t have to worry about jitter or scratchiness because there’s hysteresis over 64 points.
We’ve already ordered 10 pieces of the Diodes Inc PAM8019E to design a breakout. DigiKey has tons in stock so we recommend you buy some too, at 34 cents a-piece at reel quantity it’s hard to say no! They’re available in 3x3mm or 4x4mm package sizes, both are QFN-20. Order today and you can be bumpin’ and boppin’ with either speakers or headphones by tomorrow. afternoon.

Lawrence Abrams, reporting for Bleeping Computer:
Internet Archive’s “The Wayback Machine” has suffered a data breach after a threat actor compromised the website and stole a user authentication database containing 31 million unique records. News of the breach began circulating Wednesday afternoon after visitors to archive.org began seeing a JavaScript alert created by the hacker, stating that the Internet Archive was breached.
“Have you ever felt like the Internet Archive runs on sticks and is constantly on the verge of suffering a catastrophic security breach? It just happened. See 31 million of you on HIBP!,” reads a JavaScript alert shown on the compromised archive.org site.
The text “HIBP” refers to is the Have I Been Pwned data breach notification service created by Troy Hunt, with whom threat actors commonly share stolen data to be added to the service.
Hunt told BleepingComputer that the threat actor shared the Internet Archive’s authentication database nine days ago and it is a 6.4GB SQL file named “ia_users.sql”. The database contains authentication information for registered members, including their email addresses, screen names, password change timestamps, Bcrypt-hashed passwords, and other internal data.
As if that weren’t enough to make for a bad week for the Internet Archive — a seemingly irreplaceable stalwart resource of the web — they’re also under a DDoS attack. Jason Scott, archivist at Internet Archive, on Mastodon:
Someone is DDOSing the internet archive, so we’ve been down for hours. According to their twitter, they’re doing it just to do it. Just because they can. No statement, no idea, no demands.
