NEW PRODUCTS – Small, Medium and Large White LED Backlight Modules
NEW PRODUCTS – Small, Medium and Large White LED Backlight Modules – These pretty strips of light are plastic diffused backlights, often seen in LCD displays. Normally they’re tucked behind the LCD and shine white light from below. Here, we’ve got the LEDs available individually and they’re really cool! Each LED is encased in a 3.5mm thick strip of a acrylic. The acrylic strip is a special type that is very good at diffusing light, so even though there is only one single white LED, it provides near-uniform lighting. The other flat side of the strip has a reflector on it so you only get light from the top (otherwise the backlight would lose 1/2 the brightness unnecessarily).
You can treat this backlight just like an LED, light with ~3V at 20mA current and you get a pretty shape that you can mask with vinyl or draw over with marker. Gels can be used to change the color. We think these would make great wearables without the need for EL or inverters, they’re much brighter than EL and use less battery. The trade-off is these are not flexible at all.
The small backlight has a 0.5″ by 1.5″ (12mm x 40mm) lit area, the medium has a 0.8″ by 3″ (23mm x 75mm) lit area and the large has a 1.7″ by 3.4″ (45mm x 86mm) lit area
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.

I just ordered a couple of these – they look very cool! Can you advise if the acrylic away from the leads is inert and safe to cut/grind? I might need to round the corners for example.
Cool! I just bought a few of these. Any idea if it is safe to cut or grind the corners of the acrylic if I need to resize slightly? I.e. is the LED just embedded in one end and the rest of the acrylic is just inert for diffusion?
