The Adafruit PyBadge an all-in-one compact dev board programmable in CircuitPython. Full of features squeezed onto a 3 3⁄8 × 2 1⁄8 inch rounded credit card sized rectangle. It’s a perfect wearable badge, but can be used for many projects.
The PyBadge is powered by our favorite microcontroller, the ATSAMD51, with 512KB of flash and 192KB of RAM. There is an additional 2 MB of QSPI flash for file storage, handy for images, fonts, sounds, or game assets.
On the front, there is a 1.8” 160x128 color TFT display with dimmable backlight. There is fast DMA support for drawing, so updates are incredibly fast. There are 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 are also 5 NeoPixel LEDs to dazzle or track activity.
On the back, there is a full Feather-compatible header socket set, so you can plug in any FeatherWing to expand the capabilities of the PyBadge. There are also 3 STEMMA connectors - two 3-pin with ADC/PWM capability and one 4-pin that connects to I2C - you can use this for Grove sensors as well.
For built-in sensors, there is a light sensor that points out the front, and a 3-axis accelerometer that can detect taps and free-fall. To make bleeps and bloops, there’s a built in buzzer-speaker. For projects where you need more volume, you can plug in an 8 ohm speaker.
You can power the PyBadge from any of Adafruit’s LiPoly batteries, but this 400mAh one is suggested. An on-off switch will save battery power when not in use. Or power the board from the Micro USB port - it will also charge the battery if one is attached.
There is a variant on the Adafruit PyBadge, the Adafruit PyBadge LC, which has a subset of the PyBadge features.

Every time we commit new code to CircuitPython we automatically build binaries for each board and language. The binaries are stored on Amazon S3, organized by board, and then by language. Try them if you want the absolute latest and are feeling daring or want to see if a problem has been fixed.
All previous releases are listed on GitHub, with release notes, and are available for download from Amazon S3. They are handy for testing, but otherwise we recommend using the latest stable release. Some older GitHub release pages include the same binaries for downloading. But we have discontinued including binaries as assets on newer release pages because of the large number of files for each release.
Update UF2 Bootloader
Latest version: v3.13.0
The bootloader allows you to load CircuitPython, MakeCode, and Arduino programs. The bootloader is not CircuitPython. You can check the current version of your bootloader by looking in the INFO_UF2.TXT file when the BOOT drive is visible (FEATHERBOOT, CPLAYBOOT, etc.).
It is not necessary to update your bootloader if it is working fine. Read the release notes on GitHub to see what has been changed. In general, we recommend you not update the bootloader unless you know there is a problem with it or a support person has asked you to try updating it.
To update, first save the contents of CIRCUITPY, just in case. Then double-click the reset button to show the BOOT drive. Drag the update-bootloader .uf2 file to the BOOT drive. Wait a few tens of seconds for the bootloader to update; the BOOT drive will reappear. After you update, check INFO_UF2.TXT to verify that the bootloader version has been updated. Then you will need to reload CircuitPython.
