Re: Help with RGB LEDs

You can do that if the SAIO outputs that state in one form or another. You just need a chip that supports the number of inputs that you need while having enough outputs to drive the LED.

Re: Help with RGB LEDs

Sota mentions it here: http://www.sudomod.com/forum/viewtopic.php?f=9&t=1615&hilit=attiny&start=20#p18125 . He also has a wiring diagram here: http://www.sudomod.com/forum/viewtopic.php?f=9&t=1615&hilit=attiny&start=20#p18133 . I imagine it will be similar with Kite's board except you'll use the exi...

Re: Help with RGB LEDs

He actually uses an ATMega (I think an ATMega328P). He uses it because the way the powerboost works. If he would have used an ATTiny, he would only have gotten two statuses to work. I'm not sure how your board operates (if it needs the ATMega or if an ATTiny will do). As for the programmable aspect,...

Re: Help with RGB LEDs

Sota did a build with an RGB LED. The concept should be similar to yours. http://www.sudomod.com/forum/viewtopic. ... iny#p18098

Re: X/Y Button Template

Someone already did something similar, but there is a bit of room for error with their template: http://www.sudomod.com/forum/viewtopic.php?f=8&t=1167

Re: [For Sale] Safe Shutdown v1.2 (for PowerBoost)

Hi! Is there a way to connect external led that will light up when there is low battery power? Btw ordered 2 powerboost :) Not something I've experimented with yet, but you may be able to connect an LED between 3.3v and LBO. As LBO drops to ground, the LED should light. I'll investigate further. Th...

Re: SD card help

I have exactly the same problem and I've checked several times my wiring and I think it's ok. I can't imagine in which part I'm going wrong It has been said that not all SD cards work without additional filtering. Unfortunately isn't always enough to just have the one bypass cap to get it to work. ...

Re: [Guide] Graceful shutdown switch without Pololu

I will be trying it either way! I got a few different brands of JFETs on the way to test. Looking to make a few pcbs that include this plus a few other features to save some space.

Re: [Guide] Graceful shutdown switch without Pololu

Are official Fairchild JFETs a problem then with the original schematic? I was reading the datasheet for their JFETs and it says the source and drain are interchangeable.
