Aurum versions 1.0 and 1.1
The Aurum v1.0/v1.1 are PIC18F4550-based boards designed to cater to the academic requirements of an electrical engineering undergraduate student, in a basic course in microprocessors and microcontrollers. Aurum is an easy-to-use board that is USB programmed and powered, and hence can function almost as a stand-alone unit, requiring only a connection to a host computer. The programming protocol is free and easy-to-use, using standard Microchip-Technology tools. The following table shows some differences in architecture of the two versions.
||Based on a DIL-Packaged PIC18F4550
||Based on a TQFP-Packaged PIC18F4550
||29 I/O lines available for user's configuration
||29 I/O lines available for user's configuration, with dedicated connectors made available for LCD and switch/LED connections.
||USB programmable and powered
||Powered and programmed through USB, but can also be programmed using a PIC emulator (connectors are provided for that purpose)
||Light weight and portable
||Light weight and more easily portable
It should be noted, that in principle, the Aurum v1.0 and v1.1 do not differ in architecture or programming. The difference lies only in device packaging, layout and features to consider a user's convenience.
