for Raspberry pi 4 Port USB HUB HAT Compatible with USB2.0 1.1 for Various Version of Raspberry Pi Perfectly Fit Zero/Zero W/Zero WH Serial Debugging Onboard USB to UART

Update: after pretty much giving up on this thing, I unscrewed it from the Pi Zero W and noticed there were a couple tiny UART RXD TXD switches on the board, set to the OFF position. I figured what the heck, I'll try switching them ON and see what happens. Low and behold, I get boot messages. I don't recall seeing any mention of these in the documentation. So here's what I did to get it to work:1. Switch UART RXD TXD switches to ON position.2. Attach to the Pi Zero W.3. Plug provided USB cable into mini USB port labeled UART.4. Plug other end of USB into the Mac.5. Open a Terminal and type the following command: screen /dev/cu.SLAB_USBtoUART 1152006. You should see boot messages scrolling past on your terminal. If you do not, it is possible that the boot process has already finished and is waiting for login. In that case, try typing your credentials and see if it logs you in.Still rating 3-stars for lack of documentation and missing screws.-TN====================================================USB hub seems to function ok. Mine didn’t come with enough screws to attach it securely to the Pi Zero W, so seemed a little on the flimsy side. I also tried for a couple weeks to get the UART to connect on OSX Catalina, but no joy. That was a big factor for me purchasing this model, so disappointing. I ended up giving up and purchasing a separate UART cable.

Solved my problem to too few ports on my RPi4, but installation with a USB cable was awkward and it did cause the Pi to hang on reboot. I replaced it with an RPi4 specific unit. Probably is great on a PiZero, but it's not right on a RPi4 as advertised.

The small USB-micro bridge that connects the USB hat to the Raspberry Pi Zero is a little short of being perfectlyaligned with the height of the 40-pin GPIO connector on the opposite side of the Zero. It can be made to fit, but I really don't like having to force something together, when the Design Engineer neglected to check for proper fit of all components.

Tried the Zero4U. That did not work. This one did worked like a charm! It lights up when a USB device is connected. Very cool. It even has UART, but I haven't tried it yet. The perfect accessory for your Pi Zero or Pi Zero W. Now if only there was a case/enclosure made for this.

Didnt fit to great over the gp but still works great . I was able to put it together as shown on my pic i can connect the gp a different way still very happy with the performance

great

👍👍

Doesn't fit. 3 separate Pi Zeros and 2 of these hub hats - none of them fit. The micro usb to micro usb connector is too short. I know it's not my soldering as I got one of the Pi Zeros from Raspberry fully assembled.Finally got the hat onto the Pi, but it's putting a fair bit of strain on the GPIO pins. The spacers provided would make it impossible to fit the micro to micro adapter, if anyone was interested.I'll try some sandpaper on the plastic GPIO connector and see if that straightens things out...

Diese kleine Platine ist eine super Ergänzung. Anstecken und es funktioniert.Ich wollte den Rapsi Zero mit einer zusätzlichen seriellen Schnittstelle ausrüsten und bin bei der Bestellung leider von einer anderen Voraussetzung ausgegangen. Die serielle Schnittstelle wird zum Monitoring des Bootvorgangs benutzt und nicht als Erweiterung. Als Raspi-Bastler war es zum Glück kein großes Problem. Die USB-Leitungen der seriellen Schnittstelle führen dicht an der USB-Buchse 2 vorbei. Diese Leitungen also nur etwas aufgekratzt, zwei Drähte aufgelötet und mit der USB-Buchse 2 verbunden, die Stifte RX und TX an der 40-poligen Steckerleiste entfernt, und schon hat man die Erweiterung, eine zusätzliche serielle Schnittstelle. Zu beachten ist jetzt, dass die USB-Buchse 2 nicht weiter benutzt werden darf!!Da alles zufrieden läuft, gibt's auch 5 Sterne :-)

Il raspberry pi0 ha un unica pecca, a seconda dell’uso che se ne vuol fare, la mancanza di porte usb. Con questa hub hat si risolve in pieno il problema e nel contempo si mantengono ridotte le misure del pi0. Collegando in contemporanea un HD da 1Tb, una pennetta usb da 32Gb ed un ricevitore bluetooth per tastiera e mouse non ho avuto nessun problema di rallentamento ma questo dipende dal alimentatore di 2 Amp che utilizzo, un alimentatore più piccolo potrebbe non essere sufficiente.

Funziona benissimo anche se ho notato che il connettore gpio non si aggancia ai pin del pi,un pò strano,l'ho fatto funzionare con il cavetto usb in dotazione,spia power rossa più 4 spie verdi per ogni porta usb utilizzata,veramente fantastica per il pi zero

Perfetto inserito su un RPi 4b e funziona perfettamente come hub addizionale delle USB 2.0, lo consiglio
