Powering badge
You can power badge with either three AA-battery or through USB-C(5v).
First time usage
Badges come with pre-flashed firmware (we call it minimal) that includes two functions:
- Hardware test
- OTA update
When you turn the badge on for the first time, you will see following screen:
This means that we have tested that screen, LEDs and buttons work (or worked before we packaged them back to boxes).
In the event there will be Wifi for the badges and it’s preconfigured. So all you need to do is to proceed by pressing button A. This starts OTA process. It might take a while to complete for the download, so be patient!
If you want to change Wifi-settings, check how to do it in here.
Connecting to computer
Make sure power is turn to USB. Plug badge with cable to computer and it’s should be visible as serial device.
Buttons
Badge has joystick for navigation and four push buttons: Start, Select, A and B.

What information we need:
- Contact information how we can reach to you if we need to see the submission in live and/or let you know that you have won
- All relevant information we need to judge your submission. So videos, links to repos etc
- Information you want us to link your entry in here after the event
For the #2, if you have built miniapp on top of our game firmware, please submit PR also so we can compile it to the firmware for the others too!
#1: BEST HARDWARE MOD
Simple put: we’re looking bets hardware mod for the badge. As long as it’s connected to the badge, we’ll judge it!
#2: BEST (MINI)APP
For the second badge competition, we challenge you to develop a game or application (or firmware) for the badge.
Your app/game can be bundled in the game firmware or it can be totally standalone. The only rule is that the custom code you write has to run in the badge.
Post-event usage
WLED
WLED’s ESP32-S3 support is in experimental phase and we haven’t had success with flashing latest stable or alpha to badges.
