Adafruit Qwiic / Stemma QT 5 Port Hub

by Adafruit

This 5-Port Passive Hub board has 5 vertical JST SH 1mm connectors in a row, all with the power, ground and SDA/SCL pins connected

Qwiic, or STEMMA QT, is a very efficient way to quickly prototype an idea, but a lot of Qwiic/Stemma QT driver boards only have one port, and devices have two ports but that's only good for chaining. Maybe you want to reduce your I2C line capacitance by having a star formation instead of a looooong chain. Or maybe its just easier for your mechanical layout to have them closer to a central point.

This 5-Port Passive Hub board has 5 vertical JST SH 1mm connectors in a row, all with the power, ground and SDA/SCL pins connected. There's also breadboard breakout pins if you need. Use this hub to add as many I2C devices to the bus as you need. Complete with mounting holes so the board can be added to any system. A small power LED lets you know that the hub board has connectivity.

Please note: this is a 'passive' hub, so it isn't like you can connect 5 of the same-address-sensor-boards and have them individually work. It's only a mechanical assistant for connecting many QT/Qwiic boards together.

Simply plug and go. No soldering required, but comes with a bit of header if you prefer breadboarding.

A great little PCB if you have external sensors with the matching Qwiic/Stemma QT to connect up as it makes the wiring a lot neater and certainly more reliable than the DuPont connectors on most PCB's. It's a shame there aren't more manufacturer's (like yourself) that are making sensor PCB's with these connectors as the Adafruit ones (which have them) tend to be a lot pricier.

It does exactly what it suggests perfectly well, connecting up to four Stemma QT devices to the fifth port. The only suggestion I'd have for improvement is that it does have a green power LED, but unlike some other Adafruit breakouts there's no trace to cut to disable it. I would have liked to be able to do that without having to desolder the LED.

Going from random jumper wires to STEMMA/QT (Qwiic, sort of) is like upgrading from horse wheels and windmills to a sweet, sweet MAN diesel engine: including, I regret to say, the price. Then again, both Adafruit and Pimoroni have excellent and well-deserved reputations around here (Vienna, Austria). And it’s so tiny and cute, Adafruit should have painted it pink!
