Convex Glass Lens with Edge - 40mm Diameter

by Adafruit

The eyes have it! Add this little lens to make a big expression with the Spooky Eyes demo for microcontrollers or Raspberry Pi.

These are gorgeous glass (not plastic/acrylic!) lenses, with brilliant clarity and a nice convexity (is that a word?) They've even got a lip-edge so you can mount them easily with a 38mm cutout.

This product is just a single glass lens. Perfect for use with the Raspberry Pi Snake Eyes Bonnet guide or the Electronic Animated Eyes guide. Check out both of those for the full listing of what you'll need. Of course, these work great for other purposes when you need a convex lens.

See my review of the Adafruit Perma Proto Bonnet Mini Kit. I used this to separate a prototype weather sensor from the heat of the CPU works a treat I have purchased a number of these boards from Pimoroni, they are excellent quality, and will order again when needed

I have purchased a few of these with unpopulated GPIO. They are great for adding various hardware especially ones that would otherwise block the GPIO. Helps keep a nice flat form. I recommend with the Pi Zero for builds that will use a GPIO tft/lcd like the Iuniker 2.8.

I needed something that would allow me to attach multiple hats and this was perfect for the job. The build quality is excellent and it was really easy to set up. Pimoroni makes the best products for people who like to tinker with side projects!

Happy with this. Delivery was fast. Works perfectly and gives a more accurate temperature reading now that the SenseHat is attached to it and not the RaspberryPi.

Prodotto buono e di buona fattura; permette di “moltiplicare” la gpio del raspberry e quindi di poter usare due prodotti in contemporanea. Consigliato per fare combinazioni interessanti
