Longer SH1.0 3-pin Cables?

MakerWorld CyberBrick
1

Would Bambu/MakerSupply consider selling longer (15 or 20cm) 3-pin SH1.0 cables to allow for more remote LED hub placement? Alternatively a 3-pin SH1.0 equivalent to the 2-pin SH1.0 connector adapter board (XA013)?

Is signal integrity the reason for the current 10cm length?

The reason why I ask is that I’m designing a Cyberbrick model that is on the upper end of the scale range. For now I’m going to be unable to implement forward facing lights since all the electronics need to be in the rear, in order to keep the front area clear for other mechanisms.

If you go to Maker's Supply | Bambu Lab US Store at the header you’ll see:

using part wishlist you can wish for a part on top of posting a forum post :slight_smile:

According to the WS2812b datasheet the LED is able to be placed up to 3M from it’s signal source. But you also have to factor up to 48mA per LED so that will limit cable length.

Outside of MakerSupply you can buy precrimped SH1.0 wires and plugs in quite few length. Most of typical electronics components suppliers will have JST SH precrimped wires available. SH1.0 is also quite popular in drones - check local drone / FPV. As for Board - I may :wink: be working on getting some custom cyberbrick boards made. Hub/extender board could be added

What would be even nicer? cyberbrick rx and tx board compatible with preexisting system qwiic Qwiic - SparkFun Electronics (uses 4pin JST SH1.0) or What is STEMMA? | Adafruit STEMMA & STEMMA QT | Adafruit Learning System which uses 3 and 4 pin JST PH connectors or when size is needed STEMMA QT which also uses JST SH1.0) or DFRobot Gravity

I added the Qwiic/StemmaQT connector on the display shield I have designed for CyberBrick… it’s nice that it’s the same type of connector, just the 4 pin version. I have also bought pre-crimped wires and made my own for both Qwiic and longer ones for CyberBrick.

I ordered some 200mm cables from Amazon. They come with the female part also. But they are OH so tiny. I plan to make extension cables with these.

When you say “female” are you then talking about a part that has pins similar to the ones on the CyberBrick PCBs, but for cable mounting? I was not aware that JST made those, they are not in their datasheet for the SH1.0.

Would you mind sharing a link or maybe a photo? I’m a bit curious.

And yes, these are pretty small, especially if you want to crimp these yourself and don’t have the exact right tool for them.

Yes, that’s it. Here is the link and a pic, they also make the 2 pin version and I got those for my motors. I tend to use whatever motor is available and have a lot of TT motors without cables.

Hmmm, now how to post a pic.

Ah, OK, so the mating connectors are the PCB mount ones.

Soldering those to cables will likely be a bit annoying and fail easily. The best way to make extenders would probably be to make small PCBs with 2 of the connectors on and then you can extend by alternating between cable and PCB.

I found just the single wires with the contacts crimped in both ends and then the housings separate, so that I can make either 2, 3 or 4 pin versions.

Genuine JST pre crimped cables are available from major electronics suppliers -
SH3-SH3-28300 | JST Female SH to Female SH Pre-Crimped Lead, 300mm, 0.08mm² | RS
add some housings
SHR-03V-S-B | JST, SH Connector Housing, 3 Way | RS
and you have nice cables done.
Like @flummer said - for socket side its much easier and reliable to just get pre populated pcbs made. you can even add some mounting holes for so it can be bolted on
