BlueBox Micro is a small replica of the [[BlueBoxEnglish|BlueBox]] project. The circuit board was manufactured by JLCPCB with the 686 LEDs soldered already, so only the control circuitry on the back side had to be soldered by hand.

BlueBox Micro is a small replica of the BlueBox project. The circuit board was manufactured by JLCPCB with the 686 LEDs soldered already, so only the control circuitry on the back side had to be soldered by hand. A 3D printed enclosure was designed to roughly correspond to the shape of the original BlueBox building.
Features
- 98x7 = 686 pixels, aspect ratio 7:22
- SD card
- MCUF stream via RS232
- 115200 baud (max. 16 fps)
- stream output for all displayed frames (no matter whether they come from the microcontroller's flash memory, the SD card or an incoming stream)
- power supply: Mini-USB socket, 5 V, max. 1.1 A
Hardware
- Schematic Rev. 1.0 (PNG image)
- PCB Layout Rev. 1.0 (Gerber files)
- BOM file for JLCPCB (LED side only)
- CPL file for JLCPCB (LED side only)
- Kit Instructions Rev. 1.1
- Case v2 (OpenSCAD)
- Case front v2 (STL)
- Case back v2 (STL)
The case front should be printed with a 0.25 mm nozzle as the walls between the windows are very narrow. For the back, a standard 0.4 mm nozzle is sufficient. For assembly, three self-tapping screws (for plastic or sheet metal) with 3 mm thread diameter, 10 mm length (excluding head) and a head diameter of less than 6 mm are required. In a pinch, M3 machine screws can be used.
For better light distribution, a grey diffusor foil (e.g. Lee Filters 225 "neutral density frost") can be glued in front of the windows.
Software
This project uses the BlinkenPlus firmware.
