Built with be best Open Source EDA - KiCAD
Carefully built schematic to minimize part count, SKU count, and cost while maximizing functionality.
Features:
- ESP32C3 can run any modern embedded OS such as ESPHome or WLED
- IR Control
- RGB LEDs Support (2A per Channel)
- Addressable LEDs (Up to 4 if using RGB channels as open drain outputs)
- USB-C 5V Input (3A Max)
- 5V-24V Input Through Barrel Jack
- User LED and Button

Improvements
Schematic
Addressable RGB Digital channel didn't need Opto-Isolation, a simple NPN transistor would have sufficed
MOSFETs and Protection Diodes were oversized
Support for USB-PD would increase usability
Layout
User LED and Button positions were not ideal (Made Case Design Challenging)
All SMD components could have fit on single side
