The TSL2591 luminosity sensor is an advanced digital light sensor, ideal for use in a wide range of light situations.

That means you can separately measure infrared, full-spectrum or human-visible light. Most sensors can only detect one or the other, which does not accurately represent what human eyes see (since we cannot perceive the IR light that is detected by most photo diodes) This sensor is much like the TSL2561 but with a wider range (and the interface code is different).

So small and simple, you can use this board as an all-in-one display driver for TTL displays, or perhaps decoding HDMI\/DVI video for some other project.

We've used this breakout with 800x480 displays, so we have not specifically tested it with higher resolutions.

With the backlight off, the decoder and display itself draws 250mA.

You can power the driver over USB and then feed it video via the HDMI port. It's a very small board so great for tucking into an enclosure. It can drive our 4.3\", 5.0\" or 7.0\" displays but we really only recommend the 5\" or 7\" 800x480 as some computers do not like the low resolution of the 4.3\" and the TFP401 does not contain a video scaler, it will not resize\/shrink video!\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003eWe ship this board with an 800x480 resolution EDID, so it will be auto-detected at that resolution.

With the internal gain set at the minimum of div8, the max current is ±400mA and the resolution is 0.1mA.

The other end is sealed. The wires are even nicely color-coded: black for ground, green for signal, red for 3-5VDC power. We use SK6812 LEDs on these strips so you don't need an inline resistor and they work down to 3V logic+power.\u003cbr\u003e\u003cbr\u003eNeoPixels are addressable LEDs. That means, there are 60 RGB LEDs per meter and the strip is half a meter long so you get 30 individually-controlled RGB LEDs! You can set the color of each LED's red, green and blue component with 8-bit PWM precision (so 24-bit color per pixel). The LEDs are controlled by shift-registers that are chained up down the strip so you can shorten the strip if you like by cutting it. Only 1 digital output pin are required to send data down. The PWM is built into each LED-chip so once you set the color you can stop talking to the strip, and it will continue to PWM all the LEDs for you\u003cbr\u003e\u003cbr\u003eThe strip is made of flexible PCB material, and comes in a weatherproof sheathing. You can cut this stuff pretty easily with wire cutters. Of course, you can also connect strips together to make them longer, just watch how much current you need!
