Talon SRX Data Port Header
 

I've been trying to find a header that would work with the ribbon cable that connects to the data port header on the SRX, and I think I've found it: http://www.digikey.com/product-detai...C10K-ND/755176 Will this part work? If not, could someone direct me to one that will?

Re: Talon SRX Data Port Header
 

That part will not work. That is a .1" spaced header. The Talon SRX uses a .05" spaced header. I don't have a link handy to a part but I can find one later if someone doesn't beat me to it.

Also, don't forget your team's digikey voucher if you order anything from them.

EDIT:

Links:

I think these are all valid but double check them. It kind of depends on what you want. The .05 pitch makes these things tiny.

Thanks a ton! I've been looking at making a custom breakout for the SRX, and depending on the path forward, that female header may come in very handy. Thanks again for your help!

Re: Talon SRX Data Port Header
 

I am also thinking of making a different (better) SRX encoder breakout board.

Here's what it needs:

A 5 pin 0.1" header to match the Cui AMT103-V pinout, including Index

Two 2 pin 0.1" headers for the limit switches

A 3 pin 0.1" header for the analog pot sensor

A set of mounting screws so you can stick it to the robot!

Who wants some?

Re: Talon SRX Data Port Header
 

I think a breakout board on the Talon might make more sense than having it at the end of a ribbon cable. A nice connector is this one:

Digikey 609-3754-ND

The board wants to be designed so that it is centered on the Talon when the plug is centered in the header.

Re: Talon SRX Data Port Header
 

Speaking of the data port, the product description lists the Talon as being able to communicate over CAN and PWM, but also SPI and UART. Has anyone seen anything regarding the SPI and UART? The terms don't show up in the manuals.

Re: Talon SRX Data Port Header
 

Our team actually felt the exact same way about the current Talon breakouts; we aren't fans of the ribbon cables. We just finished designing two Talon boards, a breakout and a 5v to 3.3v analog converter, that mount directly to the Talon SRX. I've attached the white paper we've written, which includes all of the parts links on Digikey. If you'd like Gerber files or the Altium project files, I'd be happy to send them.

Re: Talon SRX Data Port Header
 

Are you saying you will be mounting the Talon to a PCB board instead of mounting it to a heat-sink surface?

Re: Talon SRX Data Port Header
 

Interesting design ideas... We were toying with the idea of mounting directly to the talon, but we went with (ironically) more ribbon cables. We basically feed all the data ribbon cables into one board that puts all the signals into a 34-pin ribbon cable which goes out to a board closer to the actual encoders and whatnot to reduce on messing with getting the encoder wires all the way back. I may end up adapting picklenerd's design into a board that supports multiple talons...I hadn't thought of using a jumper to switch between 5v and 3.3v for the quad. encoders. Maybe I'll revise our current design if we get a bit of pocket change, we JUST ordered boards tonight.

Re: Talon SRX Data Port Header
 

The breakout will be mounted to the top of the Talon. The Talon will be mounted to the chassis. At least, that is the current plan.

Don't forget the TIM. It's explicitly permitted in the 2015 rules.

Re: Talon SRX Data Port Header
 

something like this? needs mtg holes though...

Re: Talon SRX Data Port Header
 

better version...

Re: Talon SRX Data Port Header
 

Interesting. I'm digging the convergent evolution with these designs.

Are you at all worried about shorting on the bottom side of your board?

Re: Talon SRX Data Port Header
 

We're about to order some advanced circuits "barebones" compatible boards (bottom traces/pins steer clear of SRX body). We're going exclusively with AMT102V encoders, so the pinout /voltages matches those. I'll post back with info on how they turn out...
