What’s the size of a credit card and can run CircuitPython, MakeCode Arcade or Arduino even when you’re on a budget? That’s right, it’s the Adafruit PyBadge LC! We wanted to see how much we could cram into a 3 3⁄8 × 2 1⁄8 inch rounded rectangle, to make an all-in-one dev board with a lot of possibilities, and this is what we came up with.
The PyBadge is a compact board, like we said, it’s credit card sized. It’s powered by our favorite chip, the ATSAMD51, with 512KB of flash and 192KB of RAM. We add 2 MB of QSPI flash for file storage, handy for images, fonts, sounds, or game assets.
This is the Low Cost versionof our more fully featured Adafruit PyBadge. We pared down the hardware to make it even more affordable, and you can still use it with MakeCode Arcade, CircuitPython or Arduino! The LC version has the same processor chip, QSPI Flash, on/off switch, buttons, buzzer, light sensor and battery circuit. It does not have Feather headers, JST STEMMA connectors, LIS3DH accelerometer, or optional speaker connection. Instead of 5 NeoPixels there is only one in the center front.
On the front you get a 1.8″ 160×128 color TFT display with dimmable backlight – we have fast DMA support for drawing so updates are incredibly fast. There’s also 8 silicone-top buttons, they are clicky but have a soft button top so they’re nice and grippy. The buttons are arranged to mimic a gaming handheld, with a d-pad, 2 menu-select buttons and 2 fire-action buttons. There’s also a NeoPixel LED in the front to dazzle or track activity.
For built in sensoring, there’s a light sensor that points out the front. To make bleeps and bloops, there’s a built in buzzer-speaker.
CircuitPython lets you draw graphics, play wave files and print out text in any fonts – all in Python! There’s tons of sensor support as well.
Arduino is low level, powerful, but a little more challenging. You can use Adafruit Arcada to interface with the hardware and it will abstract some of the nitty-gritty details like reading buttons for you.
Here’s a list of everything you get
ATSAMD51J19 @ 120MHz with 3.3V logic/power – 512KB of FLASH + 192KB of RAM
2 MB of SPI Flash for storing images, sounds, animations, whatever!
1.8″ 160×128 Color TFT Display connected to its own SPI port
8 x Game/Control Buttons with nice silicone button tops (these feel great)
1 x NeoPixel for badge dazzle
Light sensor, reverse-mount so that it points out the front
Built in buzzer mini-speaker
LiPoly battery port with built in recharging capability
USB port for battery charging, programming and debugging
We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @ adafruit.com/blacklivesmatter
