USB Flash Board

An 8051-based system for rapid software development

Published in issue 371, November 2007

USB Flash Board

Flash microcontrollers are easy to program, which makes them suitable for rapid software development environments and educational uses. In the past, program code was usually downloaded via a serial interface, but nowadays many PCs (especially laptops) only have USB ports. Our versatile Flash Board provides a solution to this problem.
