Caught fire on second use.
1 out of 5 stars
Caught fire on second use.
Add added the Waveshare USB board to add a wireless USB keyboard to my rPI CM4 carrier board since the default ports aren't enabled by default. I was wasn't using Raspian so I couldn't just use the device tree overlay to enable them on boot. The first boot everything went fine but I moved the keyboard to a different USB port on the second boot and the TLV62130 chip (step down converter) caught fire like a candle. I contacted Waveshare through the support links provided by Amazon and they were not helpful. After I sent in pictures of the board and power supply (at their request), the told me they couldn't support the product since I didn't purchase it directly from them. Buyer beware.

    3.0 out of 5 stars Beware when connecting power
    Reviewed in the United States on August 22, 2021
    Verified Purchase
    One major flaw, power. The RPI uses a standard floppy power connect. The power connect on this is the right header, however the pinout is incorrect. What's marked as 12v on the board is actually the floppy 5v.

    Waveshare does not provide a cable to connect power to the RPI, or to correct this in the box. If you connect this direct to an arc power supply, it will be connected to the 5v rail and not the 12v rail. The device is indeed set up to run off 12v and not 5v.

    Poor oversight on waveshare part. Otherwise, works as expected for the vl805 chipset with drivers already built in.

    5.0 out of 5 stars alles Top Raspi CM4 hat jetzt 4xUSB3 und 4xUSB2
    Reviewed in Germany on July 18, 2021

    Die erste Karte ( bei einem anderen Verkäufer ) war def. Diese hier kam innerhald von 4 Tagen ( ohne Prime ) und hat direkt funktioniert. Wer mehr als nur Maus und Tastatur anschließen möchte muss zwingend den zusätzlichen Stromanschluss benutzen -- Achtung - gekreuztes Kabel verwenden oder selber löten --
    Ich habe 2 2,5" Festplatten 500GB und 2 SSD dran stecken , bei den Festplatten habe ich Schreibraten bis zu 180MB undbei den SSD liegen die Schreibraten über 250MB wenn alle 4 Datenträger gleichzeitig genutzt werden. also alles bestens
