Yes, but there is no ready made project, with files etc. They all just talk. I'm looking for something that is ready made and works! Thanks anyway!

I'm looking for a schematic for LED Christmas tree run by Arduino and eagle files as well if possible? Thx!

Does anyone have seeeduino ADK pcb board design files ready for external power supply that has 24 V, with a switching power supply or something like that, to avoid overheating due to 24 V to 5 V conversion?

The reason I'm asking this is I'm going to redesign power supply part on the PCB and I would like to know max current it has to provide, if let's say all the outputs are loaded....

What is the maximum current needed for powering the Seeeduino Mega?
8  Using Arduino / General Electronics / Re: Powering ATMEGA 2560 on: September 28, 2012, 08:16:16 am
Yes, I was thinking to replace this part with a new voltage regulator, since I will make a custom made PCB board for arduino. I don't want to have a separate PCB with voltage regulator and separate arduino board.

You mean the round jack input?

Dear SurferTim,

I will redesign the PCB of Arduino Mega and change the power supply part on it, since my external voltage supply is 24V and I have to convert it down to 5 V. So, basically I will make a new circuit or better to say replace the existing power supply part (with LM2734) on the PCB with a new one (maybe LM317 or something...). Therefor there is a lot of option now available and I would like to have the best one. You have some idea what would be the best to do?

Since it will be surface mounted, is it enough to use PCB as a heat sink?
12  Using Arduino / General Electronics / Re: Powering ATMEGA 2560 on: September 28, 2012, 07:31:31 am
Then it is probably better to use LM 317?
13  Using Arduino / General Electronics / Re: Powering ATMEGA 2560 on: September 28, 2012, 07:20:01 am
Does 7805 convert from 24V to 5 V?
14  Using Arduino / General Electronics / Powering ATMEGA 2560 on: September 28, 2012, 05:34:49 am
I will have to adjust the power supply for the Arduino Mega, since my voltage supply is 24 V. I'm thinking of using LM 317 voltage regulator. Any comment or advice very much appreciated!
15  Using Arduino / General Electronics / Re: Arduino UPS on: September 10, 2012, 08:44:43 am
What about 3.3 V Arduino? The LiPo shield boosts the voltage  from 3.7 V to 5V, but I need 3.3 V for the Arduino Pro Mini.
