First Version 417duino Schematic

This is the full-feature schematic for 417duino, designed for Radio Shack PC board 276-150 (417 holes - get it?). Power supply, ICSP, FTDI are all optional modules, depending on desired functionality.

This image was created in EAGLE 5.10.0 Light PCB design software.  I used a trial and error and error methodology to generate this schematic.  I make no claims of expertise with EAGLE, and there are decided errors that will not translate to a circuit board design.  While I consider this to be a trivial issue (this circuit is intended for a generic prototyping PC board, and have no intention of creating yet another Arduino-compatible circuit board), I reserve the right to modify and improve all documents relating to the 417duino. 

The 417duino Arduino-compatible is intended to be assembled from off-the-shelf components, in a variety of configurations for maximum versatility and economy.

0001 minimus

Rock-bottom basic support for a pre-programmed ATmega328 microcontroller, for use with appropriate regulated power supply.  Intended for least-expensive embedded applications.  Options: Indicating LEDs, Reset switch, headers for I/O pins (soldered connections recommended for embedded applications).

0010 medius

On-board regulated 5V power supply for pre-programmed ATmega328 microcontroller.  Intended for  embedded applications. Options: Indicating LEDs, Reset switch, headers for I/O pins (soldered connections recommended for embedded applications).

0011 magnus

On-board regulated 5V power supply, FDTI USB-Serial programming interface, Reset switch, Indicating LEDs, headers for I/O pins .  Intended for rapid prototyping, educational applications. 

0100 maximus

On-board regulated 5V power supply, FDTI USB-Serial programming interface, Reset switch, Indicating LEDs, headers for I/O pins .  Intended for rapid prototyping, educational applications, custom bootloader / ICSP programming and development. 

417Protoshield
The 276-150 PC board is too narrow to connect with the pin headers on Arduino-compatible shields, but an inexpensive shield can easily be assembled from another (that's right!) 276-150 PC board.

Plans and detailed instructions coming soon!
