New Products 2/9/22 Feat. Turing Complete Labs 10 Digit Monochrome LCD Display - STEMMA QT /Qwiic!

I had a pretty cool idea to use those wireless LEDs inside of the resin keycap molds that y'all sell. Would be cool AF to have keycaps that light up as well as the rest of the keyboard.

As always, the new products video is the highlight of my week! Thanks AdaTeam!

There are finer pitched LED matrices out there, but they're in the late prototype stage, intended for use in signage billboards and such. Typical pitches for these signage modules are like 1.2mm to 1.6mm, but the finest pitches in that market are less than 1mm. Tricky thing about these is, when the pitch and dot size becomes smaller, so do the traces, and things like power, noise, and RF become much more troublesome, particularly when you're dealing with video content. You _can_ gang up a bunch of them to make a big bright video wall, but you're going to see differences in each matrix, even if you have a controller that can calibrate for manufacturing differences. Depending on how the LED drivers are set up, you might see some wild color artifacts as well, again, with things like photorealistic video content. Naturally it's much less of an issue with matrices with coarser pitches. Another thing I've learned is, each matrix or module in a big LED signage display has multiple driver boards, whereas an LCD or OLED monitor only uses 1, which lets the LED modules become any size and shape display, but it also means that you need to calibrate all those panels which is at most a single process for a typical computer or TV display. The guys who were working on the signage modules told us that they should have these complications worked out "soon", so we might see crazy high resolution displays at stadiums in the near future (think 16K+). They'll cost a pretty penny, of course. They're getting to the point where it's similar to transistors on CPU dies, except with LEDs, so I'm thinking they're really really going to want an Intel or AMD engineer to help them sort out some of the stuff related to really small circuits/traces.

I'm also curious about that lcd's current... I suspect it would have to be pretty low for the panel, which just leaves the driver chip.

[@beatadalhagen]

Curious if you can get either wireless LED size in UV.

[@travismiller5548]

eager to order a bunch of these wireless LEDs and print tiny (waterproof) translucent enclsures... and put them in a bong.

[@RandomBogey]

I think casting them in resin, unless you have a resin printer, might work better. But, I like the idea of dropping them in a bong. Lol

[@AdityaMehendale]

Would the LCD-display persist even when the main MCU sleeps? (i.e. the onboard h/w handles the LCD voltages) --> In this case, an ultra-low power display would be possible without needing e-paper. Curious what the power-consumption of this module is... Who remembers Atmel's "AVR butterfly" modules? (which used to be a pain in the @$$ to program, btw)

[@rpavlik1]

Quite possibly, if it doesn't need i2c refreshes regularly

[@rpavlik1]

Looks like the driver chip BL55077(A) has a max power consumption of 400mW, which is 80mA at 5v, pretty far from eink. However it also says that the typical current in the most power hungry mode is 25uA, so that's pretty good. Answer: we need ladyada to use the ppk2 to get us good data 😁

What's with the emphatic "Not LEGO!" ?

[@CalebSkurdal]

They mentioned getting emails from Lego when they reference them

[@rpavlik1]

Lego is very defensive of their trademark, especially when you're using non-Lego, but compatible, bricks.

[@PatrickRankin]

It's an ongoing joke. It's mostly fans of Adafruit warning about Lego copyright infringement all the time, not Lego themselves.
