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.
