I can’t understant which voltages it works with. Does it works with a 3V button cell? Or does it need 5V and then it regulates to 3.3V?
Does this display contain internal current-limiting resistors or would each RGB pin need it’s own resistor? It would be great if someone…
OK, so with a little knife and solder work, I was able to use the addressable LEDs. Man, they are cool. I think SF should really consider…
That’s a neat trick, but my goal is to take the pi-top on the road with me as very light laptop with great battery life. A bit like a DIY…
This is trickier than it looks, since the LEDs are arranged in a 16x9 matrix - they have to be driven in a matrix scanned configuration.…
The LEDs are Multiplexed, not driven individually. You need 25 bits, not 144, if I’m reading the data sheet properly.
For 7-Segment LEDs, I’ve used 74HC595 as a shift register for bit shifting, and when I need to display several 7-segment LEDs, I wired…
The Teensy 3.6 does not fit in this adapter, does it? If not, how could I connect a Xbee with a Teensy 3.6?
Are there Arduino and RPi libraries for these? If so, where can they be found?
