Prototype Header Project

Eagle library with header. (Atmel_Prototype_Header.LBR) Updated July 2 2006

The old version can be downloaded at http://www.cadsoftUsa.com/  under Downloads->Librarys
You can freely use the library.


Eagle Schematics and layouts for AtMega16 and AT91Sam7S64-256 (Atmel_Prototype_Header_Files.ZIP) Updated Sept 4 2005
PDF's are included in the zip file.
Updated parts list
You may copy, use and/or manufacture the boards provided you leave the "BillArden.com" note in.
I will be adding links to manufactures from the www.billarden.com page.

Goals:
 1. To make it easier to create prototype and low production run products.
 2. To be able to reuse otherwise wasted processors.
 As with any kind of prototype it is a given that the first couple version will eventually end up in the scrap bin. If you have extra PCB space you can give them new life by adding a Processor header and drawing a line on the PCB showing where to saw it at.
  The result is a nice processor board with support hardware that you can use in Perf board prototypes.

Notes: The headers must be placed on a .1 grid

Atmel Stepper (on hold)

The atmel servo is similar to the JrKerr PicStep.
It takes commands from a PC via a serial port and controls stepper motors.
Features
  • 2 limit switch inputs for alignment.
  • 1 Halt/stop input
  • 2 PWM Stepper motor outputs for 6-wire stepper motors.
  • daisy chain 5 volt serial bus
  • Software compatible to JrKerr devices.


  • Atmel Servo  (Project is On hold)
    The atmel servo is similar to the JrKerr PicServo.
    It takes commands from a PC via a serial port and controls motors, however it is designed to be more R/C compatible.
    Features
  • 1 R/C input for manual control. (Standard .5 to 1.5 ms pulse)
  • 1 Quadrate encoder input. (500K transitions per second max)
  • 1 R/C output or PWM output
  • daisy chain 5 volt serial bus.
  • Software compatible to JrKerr devices.
  • The Set output command can be used with the R/C output version to position a R/C servo motor.
