assembled PCB "SCIMO V1.2"
  


features:

• Standalone device: video analysis and control of the LEDs is done in hard realtime by powerfull microcontroller
• Video input (PAL, NTSC, SECAM): S-Video (Y/C) or Composite (CVBS)
• USB full speed device (for initial configuration via PC)
• Included receiver for infrared remote control
• up to 240 RGB LEDs (zones) can be separately controlled
• supported digital LED / ICs and protocols: WS2811, WS2812, WS2812B
• Firmwareupdate via USB
• automatically wakes up or goes into standby depending on video signal (e.g. if TV, PC switched on/off)
• adjustable LED delay time (to compensate TV input delay)
• precise adjustable LED colors (red, green, blue, gamma) to match color on TV

Video Processing:

• Video analysis: done by very powerfull 32-bit ARM Cortex-M4 microcontroller with DSP (Digital Signal Processor) and FPU (Floating Point Unit)
• realtime operation system used in microcontroller are optimized for best performance and needed resources
• Video deocder: TVP5150AM1 from Texas Instruments digitizes analog video signal
• internal Video Data Format: ITU-R BT.656 ( 8 data bits at 27 MHz pixel clock )
• analysing each video frame (50/60 Hz) which gives very responsive and dynamic LED colors
• processing ~22 MByte/sec. of video data

technical data (SCIMO V1.2 board):

• Indicator Panel : Power , Videosignal
• Supply Voltage : 5 VDC +/- 5 %
• Input Power (Powered up, without external LEDs) : 5 V * 0.19 A = 0,95 W
• Input Power (Standby) : 5 V * 0.06 A = 0,3 W
• Board Dimensions = 50 mm * 60 mm
• Operating Temperture : 0 °C to 40 °C
• StorageTemperture : -40 °C to 70 °C
• Humidity : 10 % to 90 % (non-condensing)
• Weight : 35 g
• max. current for LEDs : max. 11 A @ 5VDC

supported color formats:

• PAL (B, D, G, H, I, M, N, Nc)
• NTSC (J, M, 4.43)
• SECAM (B, D, G, K, K1, L)

connectors:

• S-Video or Composite input (video signal)
• USB 2.0 (for initial configuration)
• power supply input ( 5 Vdc / max. 11 ampere )
• LED stripe connector (for digital RGB LED stripes)

hardware feature:

• automatic low-power standby mode
• multi video connector (S-Video or Composite or dual Composite)
• 5V pass-through power supply for LED stripes
• power supply of LEDs are switched off if SCIMO is in standby mode -> eliminates idle current of LEDs
• infrared remote control receiver
• two dual colour LEDs shows current status (video signal detection, power mode)
• onboard microswitch
• ESD protection

LED1: power state (on/off)
LED2: video signal available

Enclosure

The enclosure was produced by technology SLS "selective laser sintering" and can be ordered directly from a company which is specialized for 3D printing : SCIMO_V1.2 enclosure @ trinckle.com

The prototypes were designed and tested using the techonolgy SLS, so i strongly recommend to choose the option "Plastic Sintering" when ordering a enclosure from this company. There you can also choose a color you prefer.

Additional there are some parts needed like screws, rubber feet and so on, please check table below to see what else is needed.
