The Adafruit Feather ecosystem is so wealthy with {hardware} variety, we wished to share them, one every day. In the present day is the Adafruit 0.54″ Quad Alphanumeric FeatherWing Show – Blue!
Show, elegantly, 012345678 or 9! Gaze, hypnotized, at ABCDEFGHIJKLM – effectively it will possibly show the entire alphabet. You get the purpose.
That is the Blue Adafruit 0.54″ Twin Alphanumeric FeatherWing Show Combo Pack! We even have these combo packs in Inexperienced, Crimson, White, Yellow-Inexperienced and Yellow.
This can be a good, shiny alphanumeric show that exhibits letters and numbers in an exquisite hue. It’s tremendous shiny and designed for viewing from distances as much as 23 ft (7 meters) away. Every of the digit units have 14 segments on a darkish background and we offer you a set of two alphanumeric shows in addition to a Featherwing driver board so you can also make a clock or a 4 letter phrase.
Works with any and all Feathers!
14-Phase Matrices like these are ‘multiplexed’ – so to regulate all of the fourteen-segment LEDs you want 18 pins. That’s loads of pins, and there are driver chips just like the MAX7219 that may management a matrix for you however there’s loads of wiring to arrange they usually take up a ton of house. Wouldn’t it’s superior in the event you may management a matrix with out tons of wiring? That’s the place these Alphanumeric LED Matrix FeatherWings are available, they make it very easy so as to add a 4-digit alphanumeric show with decimal factors.
The LEDs themselves don’t connect with the Feather. As a substitute, a matrix driver chip (HT16K33) does the multiplexing for you. The Feather merely sends i2c instructions to the chip to inform it what LEDs to gentle up and it’s dealt with for you. This takes loads of the work and pin-requirements off the Feather. Because it makes use of solely I2C for management, it really works with any Feather and may share the I2C pins for different sensors or shows.
