Questions on making a minimal/custom Arduino circuit @ 3.3v/8Mhz?

Riva-

thanks.. sorry I thought I had read it was set to be at external 16Mhz..

Crossroads-

thanks..

so its just like burning a bootloader for a 5v/16Mhz set-up?

oops..post while I was typing---

I dont think I'll be doing any writing.. its to house the audio files only (going to use the PWM Audio lib posted here a while back to play some sounds...the pcb is an ODD shape..and extremely small form factor)

if a regulator can be 'had' great.. SMD of course..
but how many are that smallw ith enough current..

and that brings me back to the batteries you bring up.. something small/flat enough current for an Arduino, 8 x SMD leds (running at 10-15mA tops) but not all on at once.. max would be 5.... and the SD card

thanks!

  • Open IDE, (I use v.23 still..but have 1.0 installed if needed)

**TOOLS >> BOARDS >> **(I see Lilypad Arduino w/Atmega328 & Arduino Pro or Arduino Pro Mini (3.3v / 8Mhz) w/Atmega328)

(about the only thing that would match up...)
**I dont see a Lilypad 00 or 01.. just the Lilypad entry as denoted above)

TOOLS >> BURN BOOTLOADER >> w/ARDUINO AS ISP

QUESTION 1:
Does this mean I can just 'direct connect' with a SD card then? no buffer/logic shifter needed? and no resistor based voltage divider either?

QUESTION 2:
I use an FTDI cable like this one from eBay:

thanks.

when I eventually get to the part where I have a bootloader and I can upload sketches.. do I use the 5v or 3.3v volt pin for FTDI/sketch uploading?
