XangleBoard

Raspberry Pi Hat for Xangle Camera Server: light control for multi-camera installations (bullet-time, photogrammetry, etc.)

Features

• 4 stereo outputs for strobe lights (delay setting from Xangle)
• Neopixels connector (optional)
  
• Auto-detection from Xangle (status panel)
• Daisy chain ports (future extension modules)

Applications

• Sync strobes with Android devices at 1/6s (can vary depending on model)
• Fire multiple flashes within the same custom trigger sequence
• Control multiple Neopixel LED strips, as seen on https://www.instagram.com/p/CNi1DruBnAu/
• Use as a simple flash trigger instead of the usual sacrifice-camera

Compatibility / requirements

• Raspberry Pi 3b, 3b+ or 4b
• Xangle Camera Server v21.04.27+ (Pro or Capture license only)
• Your Xangle license must allows a number of nodes (or cameras) equal or above your total number of XangleBoards (get a 12-cameras license for 12 boards)

Neopixels features and limitations

• Power up / drive up to 120 RGB or RGBW pixels on a single board (one board on one Raspberry Pi)
• Adafruit Mini Skinny NeoPixel Digital RGB LED Strip: https://www.adafruit.com/product/2969
• Suggested power supply: 
  - https://amzn.to/35JZBdd: 60 RGBW pixels per power supply - 5V 6A 40W
  - https://amzn.to/3AyuT51: 120 RGBW pixels per power supply - 5V 10A 40W
  - https://amzn.to/3y4oJbH: 120 RGB pixels per power supply - 5V 8A 40W
• Any other NeoPixel product should work but might require some custom connectors and/or a different power supply. Contact us if you need any help

Neopixels control from Xangle

• Create unlimited groups of lights to assign colors, bmp files, or brightness level.
• Individually control the brightness of the white (W) pixels vs the RGB pixels
  
• Presets system per global group configurations
• Master on/off switch ("L" key from the dashboard, or "next" key on a bluetooth powerpoint presenter)
• Automatically change the preset at trigger time (demo: https://www.instagram.com/p/CPUdUOIBLQW/)
• Renaming per Pi (for easier grouping)
• "Identification" button (makes one strip blinks for visual identification across your system)
• Upload BMP files for animation, with speed control (BETA)
• Auto turn on/off with exposure and/or countdown duration (see demo here: https://youtu.be/iECjM9Vvmi0)
• Upcoming: API control
