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.
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).
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).
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.
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.
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!
