Group,
Besides wanting to add the buffer chips in a low profile out of the way fashion, I was also thinking to make a few other small changes. Presented here for your approval. -Add some power on LED's to top of board. -Add a DB-9 foot print over top the .1" matrix of holes, if the space is needed for a chip, it can be placed over top the DB-9. -Add the buffer chips, but keep them as close as possible to the edge card connector, thus allowing maximum space for prototyping. -Redo the silkscreen so there are lines in a grid of 10 by 10 holes (presently, I think it's 20 by 20) I'm not sure if KiCad can be switched to a manual mode to allow such overlapped pattern of components/holes. Time to learn. Regards, Josh |
