21 pin solder pad breakout board

(1/1)

G8B4Life:
While looking around for ways to avoid hardwiring my latest purchase (thanks for the mass of same colour wires Athearn!) I found what I was looking for, a proper 21 pin solder pad breakout board. I haven't bought any at the moment as the board is too long for the space available to me; and I've not used AliExpress before and I'm a bit loath to try them, so I'm putting them out there to the group incase anyone else sees a use for their installs:

The board length isn't given but it appears to be about 5 time the width of the plug itself so the approximate length of the board could be worked out from the NMRA DCC standard.

I know TCS and SoundTraxx sell something similar, but they are only 9 + 2 (speaker) solder pads and they are not well priced for what they are.

These TCS boards appear to have enough pads to cover a Railpro install.  Not the cheapest, but available a bit cheaper elsewhere.  I just ordered a pack tonight for my own installs, I'll try to let you know how it goes.

G8B4Life:
Those TCS boards must have changed very recently, this is what it used to be; only enough pads for the 9 pin JST.



Now that they've gone solder pads for 17 of the 21 pins which works for RP with it's two harnesses I'll have to look and see if I can find them at a good price. Bill, these new TCS breakout boards might be something to look at stocking.

Of note, TCS also now has the mating male 21 pin board.

I'll look into it!

I can sell these for $21 US per 5 pack including shipping in the USA.
