RE: [Project] Where now ?

["Keith Doxey" <ukha@xxxxxxx>]

John,

I'm OK for assisting with PCB design and the company I use for my KAT5
PCB's
are very reasonable. Board quality is excellent. For a Microcontroller
board
is it not practical to make them yourself due to the complexity and large
number of holes to be drilled.

Even for KAT5 I recon that the prototype boards I made cost me well over
£50
each in time, materials and broken drillbits. That was excluding
components.

Just looked at the Rabbit site and realised there wont be that many holes
because its Surface Mount. That makes it all the more important that the
board is professionally produced as the solder resist mask will be
essential.

Keith
