Unexpected Maker Bling by Unexpected Maker

There are 3 versions of BLING!

All versions of BLING come with a wonderful 40x8 RGB LED matrix made up of tiny 1x1mm addressable LEDs. They are all also the same size (99x22m) and come with 2.5mm half cut holes to allow for easy mounting using M2.5 screws.

What makes each version different is what components and features come on the back.

Hello BLING!

The full version of BLING comes with an ESP32-S3 with 8MB of Flash, 2MB of PSRAM, and a bunch of onboard features and peripherals. Want to build a cool RGB Clock with custom alarm sounds? No problem! Want to build a portable Web Radio device? Yup, you can do that too! Want to play with captured audio? Maybe a nice audio level display? BLING has you covered!

Bling also comes with a user programable power switch to enable or disable the power to the LED matrix (more on that below), plus 4 user programmable buttons and a USB-C connector for power and for charging a battery, if you connect one.

Hello TinyBLING!

TinyBLING doesn’t have an included ESP32-S3 + peripherals on the back, but instead provides headers to plug in an Unexpected Maker Tiny board (TinyPICO, TinyS2, TinyS3 and the new TinyC6) to act as the brains for your project.

You also get a STEMMA/QT connector and a bunch of IO and power broken out on an extra header, for easy expansion. TinyBLING still has a user programable power switch to enable or disable the power to the LED matrix (more on that below), plus 4 user programmable buttons.

Finally, hello SoloBLING!

SoloBLING is just the 40x8 RGB LED matrix on its own. It provides the BLING, you provide everything else.

CircuitPython 10.0.0-beta.0

This is the latest development release of CircuitPython that will work with the Unexpected Maker Bling.

Alpha development releases are early releases. They are unfinished, are likely to have bugs, and the features they provide may change. Beta releases may have some bugs and unfinished features, but should be suitable for many uses. A Release Candidate (rc) release is considered done and will become the next stable release, assuming no further issues are found.

Please try alpha, beta, and rc releases if you are able. Your testing is invaluable: it helps us uncover and find issues quickly.

Absolute Newest

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. These releases are even newer than the development release listed above. Try them if you want the absolute latest and are feeling daring or want to see if a problem has been fixed.

Previous Versions of CircuitPython

All previous releases of CircuitPython are available for download from Amazon S3 through the button below. For very old releases, look in the OLD/ folder for each board. Release notes for each release are available at GitHub button below.

Older releases are useful for testing if you something appears to be broken in a newer release but used to work, or if you have older code that depends on features only available in an older release. Otherwise we recommend using the latest stable release.

Install, Repair, or Update UF2 Bootloader

Latest version: 0.35.0

The UF2 bootloader allows you to load CircuitPython, MakeCode, and Arduino programs. The bootloader itself is not CircuitPython. On Espressif boards, the UF2 bootloader is called TinyUF2. If the TinyUF2 bootloader is installed, you can check its version by looking in the INFO_UF2.TXT file when the BOOT drive is visible (FTHRS2BOOT, MAGTAGBOOT, HOUSEBOOT, etc.)

In general, it is not necessary to update TinyUF2 at every version change. You can read the release notes on GitHub to see what has been changed. Update if you've been told about a necessary change or a bug fix.

Note: CircuitPython 10 and later, on Espressif boards with 4MB flash, requires TinyUF2 0.33.0 or later. The flash partition layout has changed (details).

If TinyUF2 has never been installed on the board, or it was removed by erasing or overwriting the flash, it must be installed in order to flash .uf2 files onto the board. But you don't need the TinyUF2 bootloader to upload .bin files. They can be uploaded using the built-in ROM bootloader, with the Adafruit WebSerial ESPTool or esptool.py.

Warning: Installing the TinyUF2 bootloader will erase everything that was previously on the board. Save any files in CIRCUITPY for which you don't have backups.

There are several ways to install the TinyUF2 bootloader on your board. Check to see if your board's manufacturer provides specific instructions. For Adafruit boards, consult the Factory Reset page in the Learn Guide for your particular board (example).

The easiest way to install TinyUF2 is to use the OPEN INSTALLER button (see above, in the CiruitPython sections). You can also use the Adafruit WebSerial ESPTool, or esptool.py, as described in the Factory Reset page.

  • If you are not using the OPEN INSTALLER button, download the combined.bin file using the DOWNLOAD BOOTLOADER combined.bin button below. (If you use OPEN INSTALLER, it will do the download itself.)
  • First, place board in ROM bootloader mode:
    • Plug board into a USB port on your computer using a data/sync cable. Make sure it is the only board plugged in, and that a charge-only cable is not being used.
    • Press and hold the BOOT button (sometimes marked "B0").
    • Press and release the RESET button (sometimes marked "RST").
    • Release the BOOT button. This starts the ROM bootloader.
  • Then proceed with OPEN INSTALLER or one of the other tools.
  • After the TinyUF2 firmware installation is complete, press the RESET button on the board. A new drive BOOT drive should be visible in your file browser.

    • After installing TinyUF2, enter the UF2 bootloader by double-clicking the RESET button. On boards with an RGB status LED, you usually tap reset once, wait for the LED to turn purple, and tap again before the purple goes away. On other boards, consult the board documentation.

    If you are updating TinyUF2, look at INFO_UF2.TXT to verify the new version of TinyUF2, by checking the version number. Then you will need to copy the CircuitPython.uf2 file to the BOOT drive.
