Re: Higher power from L298 etc.

Mariss -

No problem - I can understand that the G2002 would have demanded a
considerable amount of attention! Sounds like it will, as you say,
prove to be a very exciting project; I wish you well with the rest of
its development.

Glad to hear that the G298 is going to get some attention soon - I
would be most interested in taking a look at one of the betas when
they are available, as I have an immediate application need for the
extra power.

Regards,
Tony
