40pin DIP Module Using XS1-L1-48

[Omer]

This is pretty cool, thanks for publishing it Corin!

I ordered a few of each set of gerbers, will report when I build them (which might take a while).

Now, if only I could get my hands on some chips... ;)

Does it matter to people that it doesn't have an xtag? That is, you would need an xtag as well to really use it?

What would the preference be generally - to have a wider module with 2 48-pins on it (one for xtag) and a mini USB, or to just keep it as simple as possible and have it as proposed so far?

XTAG is (IHMO) essential.
You can see the power of the toosl if you debug! I would not be able to get anything done without debug. & IWould rather skip USB than skip XTAG. Or is the XTAG exposed over USB??

BTW: why not skip FTDI for the Serial<->USB and use the same solution as the arduino (AT90USB)?? It is a tad more compatible to my experience.

I think what Dan was getting at is, should:

- The XTAG2 be separate (as it currently is) on the 48 board - this lowers the cost, and is better when it is integrated into systems, but you require an external XTAG2
- The XTAG2 be integrated onto the same PCB - this increases the unit cost, but makes it much easier as a starter kit as it's all there in one PCB.

Option 1 for me. So long as the 48 board is available to purchase seperately. At which time also sell the XK-1A seperately and then people can buy any configuration of boards and the number of XTAG2s required. :)

Yes, I would prefer option 1. Cheaper and saves board space.

I vote for external XTAG2 as well!

[Omer]

Another vote for external XTAG!

In peoples opinion are DIP modules are good way to go for development?
Hence, would anybody be interested in bigger DIP type modules (e.g. 64-pin with more I/O)?

A larger (yet still compact) module with an L2 (or even a G4!), some SRAM, Ethernet and/or USB connectivity would be awesome (something along the lines of this module, preferably with a sensible I/O connector). IMO it doesn't make much sense to have an L1 on a bigger DIP module.

A module like this would simplify the design process for utilising multi-core XMOS devices in custom designs quite significantly.
