Micro XLR Hookups

Hello everyone! This is my first post on the pedalPCB forum! I'm a new builder who has built 2 pedals so far but I'm waiting for something I'm truly proud of for a build report.

I just finished soldering the PCB for the UniCab I just got and was interested in getting a MicroXLR board to add for the output to match the DSM OmniCabSim the pedal is cloned from. Does anyone knows how I would connect up the optional ground loop switch? I assume I just add a simple On/Off toggle switch and connect one port to ground and the other is left open?

I have experience with through hole soldering but have never worked with SMD components but I assume with some videos I can figure it out. If the PCB comes with a solder paste template I'm sure it would be much easier. Can any past purchasers can inform me on if it comes with that or not? Another thing I am contemplating is if this will fit into a 125B enclosure with another regular sized pedal PCB?

If anyone could share their experience using a Micro XLR board or answer some of these questions I would greatly appreciate it! Thanks in advance

Exactly.

It does not, but the components are all 0805 or larger so really not too difficult to solder by hand.

With that said, I have an assembled prototype here if you want it...

If you’re working with Micro XLR connections, it’s important to match both pin configuration and signal direction carefully. Using balanced cables and quality components like the SC3120A can help ensure cleaner audio transmission with minimal interference. It’s also worth double-checking grounding and shielding, especially in pedalboard setups, to avoid unwanted hum or noise in your signal chain.

Thank you so much, you saved my day <3
Edit: My problem is resolved.

OK. After a few too many work-for-salary evenings, I assembled my MicroXLR. Easily the worst solder job I've done in decades :p. Now I need to build the board to connect to it (a Darkgllass Alpha Omega clone from AionFX). The only other SMD I've done are adapters for SOIC or transistors. I wouldn't have thought the largest pieces are actually the hardest to handle.

a drop of gel or liquid flux on the joints and then 2-3 seconds of reflow would probably make most of them look alright.

still good job putting it together!

Hmm. When I touch with soldering iron, I tend to poke the bits around. I do have a heat gun, is that useable for reflow or will I destroy the components?
