Title: 21 pin solder pad breakout board
Post by: G8B4Life on May 02, 2020, 10:40:08 AM

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.

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.
