XStamp board

Version: 1
Status: Under development
License: Custom Licence
The proposed XStamp board is based on the XS1-L1-64QFP XMOS chip, and will be a self-contained 40-pin DIL prototyping module, 0.8" wide. On-board 3.3 V and 1.0 V regulators will be provided, and a miniature connector which will allow debugging with a the XTAG-2 unit, via a small adapter board and cable.
Pin spacing will be 0.1", so the module may be used with solderless breadboards and standard prototyping boards.
A prototyping board designed specifically for the XStamp will be available.

I could not reach to see the final size of the board on uploaded picture. could you please mention it here?
how many layers will contain this board? 4?
thanks!

The uploaded image isn't at all clear for some reason. Overall it's 1" x 2.1". It'll be two layers.

It looks forward to a stamp board because it is useful for the experiment!
I want to help you, but I have no technology to create new PCB......

Just to put it out there, I'm intending on ordering at least 5. More interest means a bigger run which probably means lower prices. Who else wants some? :-)

I'm sure there will many takers. I'll take a couple if the price is right.

Leon, have you any pin out details you can post?

It will be something like:
Pin Function
1 X0D2
2 X0D3
3 X0D4
4 X0D5
5 X0D6
6 X0D7
7 X0D8
8 X0D9
9 X0D12
10 X0D13
11 X0D14
12 X0D15
13 X0D16
14 X0D17
15 X0D18
16 X0D19
17 X0D20
18 X0D21
19 X0D22
20 GND
21 X0D23
22 X0D24
23 X0D25
24 X0D26
25 X0D27
26 X0D32
27 X0D33
28 X0D34
29 X0D35
30 X0D36
31 X0D37
32 X0D38
33 X0D39
34 NC
35 NC
36 NC
37 NC
38 +3.3V Output
39 +5V Input
40 +5V Input
I think that is every available pin. X0D0, X0D1, X0D10 and X0D11 are needed for the SPI flash memory.
I might have to juggle the pins to help with the layout, but it would be nice if I could keep them sequential.
There will be four spares (NC). I could make it a 36 pin module, but might not have room for everything.

Hi Leon
Any update on your board?

is this dead in the water? Would like to see it with no pins, suitable for SMT mounting
