Firmware
<Must-still-be-uploaded> System administrator, please find a way to allow me to upload a file called:
hopebadge-0.8.14.bin
...if you want I will compress it in some way or modify its filename or file extension. Nothing I've tried so far has worked. If you want to test this, just make a empty file with the name above and try to upload it.
Description
===>This photo should, of course,
be replaced by a spiffy photo of the HOPE XV badge <===
Features
The HOPE XV Electronic Badge has lots of cool features!
- Lots of colored blinky lights (16 WS2812 or similar)!
- ESP32-C3 microcontroller
- MCP73871 LiPo LiPo battery charge controller.
- Feature 2
- Feature 3
- Feature etc
Open Hardware
The HOPE XV Electronic Badge is totally Open Hardware!
- The repository linked appears to be correct (REL_0.8.14), but does not specifically mention HOPE, so looking for confirmation.
It is also totally hackable.
BOM
This bill of materials is based on the KiCAD project. There are a number of components that are not populated on the badges distributed to attendees.
