Stamp carrier board dual row 20-pin connector
Archiver
Posts: 46,084
Hello all,
This is the first time I tried sending a message to this group as I am new
to the parallax basic stamp so bare with me.
I am working on a project in which I wish to interface to my basic stamp
super carrier board as solder-free as possible to maintain a modular
design. I am currently planning on using a ribbon cable with a db-25
connector (like a parallel port) on one end and a dual row 20+ pin
connector on the other end. (the type of connector that you connect an ide
hard drive or floppy drive with but shorter). The db25 connector will then
be used to interface to existing project circuitry.
My problem lies in connecting the other end of the ribbon cable to the
super carrier board. Unfortunately, the isn't a male dual row 20 pin
header on the carrier boards but instead a 20 pin female socket that a
header would fit into. I can't plug a dual row 20 pin female socket of the
ribbon cable into the 20 pin female socket on the super carrier board. I
am looking for any ideas about how others have solved or would solve this
issue. Does it make sense to plug a male header into each female connector?
Thank you in Advance,

I bought some single row headers from Digi-Key, #929647-02-36-ND. Both ends
of the header pins are probably long enough to connect female to female. I
am not familiar with the carrier board. If it has dual row sockets, the
plastic header support may be too thick, but no problem if it's single row.

With a super carrier board I have used a 20 pin terminal board and
connected with a ribbon cable with connectors at each end. Makes for great
screw connections.
Not on drop of solder in this project.
The 20 pin terminal board is available with AutomationDirect, Newark,
McMaster Carr and Alliend Electronics.
Parallaxinc also has an industrial board which can plug onto an OPTO22
rack.
The 50 pin female header is on the bottom side.
The industrial board can also plug on to male headers on your custom
board.
I also used the ParallaxOEM board which has a 20 pin single row
connection which can plug directly into 20 pin female headers. Actually these
plug in great into a solderless bread board.
These approaches may not be what you are looking for, but I thought you
may want to know of the options that are out there for plug and play.
However after 30 years of fighting soldering I just recently bit the
bullet and learnt soldering on a ParallaxINC OEM stamp. Believe me it worked
the first time and life has never been the same since. So why not remove the
female header on the super carrier board and solder in male headers just for
the fun of it [noparse]:)[/noparse]. Just kidding there.
Jameco offers a great solder starter kit.

Warning: note that the pin numbers move around if you do that. The two
rows swap, so the order becomes 2,1,4,3,6,5,8,7, etc instead of
1,2,3,4,5,6,7,8, etc. This is not a problem if you know about it and plan
for it.
