Universal SPI Box

A quicker way to program microcontrollers

Published in issue 353, April 2006

Universal SPI Box
Lots of microcontrollers can be programmed over an SPI bus. Driving this interface from a PC’s serial port using a couple of extra components is economical but slow. A better solution is the SPI Box described here, which gives acceptable speed even when used with a USB-to-serial converter.
Q: Hi did you realise that both the printed & downloadable PCB layouts for the SPI box project (April 2006) have no holes marked for the components ? Do you have a file which has the holes correctly shown which you could email me ?
A: Due to conversion problems experienced with the PCB files supplied by the author of the SPI Box project we have been unable to print PCB artwork with holes. As an alternative solution we are now offering Gerber files for the relevant board. The Gerber files are supplied free of charge and contain all PCB drilling information.
