Ordering the Alpha board

Wow Exxos that is quite a feat of engineering. I just compared your new board to my 520 STM board.

Cool! well actually base form as STF of course

but all that now "blank space" will be where all the expansion ports will go

Well I am shipping sockets for them all anyway. Problem is, if a chip gets red hot , then unsoldering it will be a pain.. also if something is wrong somewhere, might need leg bending, track cutting etc...

Soldering direct is best for sure, but not a good idea on a test board..

Cool, sockets it is then

Glad you are all getting them pretty quick! Thanks for everyone's support!

I will be listing 4 more boards in my store shortly... those are the last ones... I'm not producing anymore of these boards as of course it is un-tested.

See the roadmap for clues on whats to happen over the next year... viewtopic.php?f=19&t=1028

I will list the last 3 boards in my store later today.. but please don't order any other parts as I can only send the board in a jiffy bag and can't pack other items in there as well (not without being crushed)..

Chris I've been looking for the schematics for the board, I have enough parts to start building. I want to check the resistance on the pullups prior to starting full build up. Also is the DiagROM image up some where? Maybe we could have a thread for debug tools. Hope to have power on by next week end. The memory board and processor I just ordered from your store is going to be my long pole.

Thx

Hi PaulJ

When building the board I used a combination of the following to help:

Schematics diagram is here - viewtopic.php?f=19&t=199
Parts List is here - viewtopic.php?f=19&t=1040#p7982
Silk screen layer image to help with placement (in parts list area) - viewtopic.php?f=19&t=1040#p7984

I found that printing the schematic out and the silk screen layer (inverting so black background is white) helped when working on the board
