HAT Brick: 5V power-supply without USB-connector but using additionally solded cable onto the HAT

[yvo]

Dear List

I have to use the 5V power-supply of the HAT Brick additionally to the 5-28V DC-input. But for constructive reasons (no available space), I cannot use an USB-connectors.

Question:

• Is there a possibility / location to sold a cable directly onto the HAT Brick?

With soldering directly a cable, I could use the additional power-supply (which I have to use for several reasons additionally to the 5-28V DC-input, see https://www.tinkerunity.org/topic/11345-hat-brick-und-strompi-3-mögliche-konflikte-bei-serieller-kommunikation-respektive-problem-bei-konfiguration-von-strompi-3/ ) even within the very small space available where the RPi and HAT are installed.

Looking forward to any ideas and suggestions.

Cheers,

Yvo

Hi Yvo, there is a resistor beneath the USB-C jack. Please see the above screenshot. In that screenshot you look through the PCB. You want to connect your cable somewhere to the USB-5V-IN signal. One possibility is that resistor.

Dear batti

Thank you very much for the advice and pointing out the precise location. I had a look at the HAT itself, puhh, this is all pretty small. I guess, this will exceed my skills of soldering 😟

I re-checked the available space between the USB-socket and the case were the RPI and the HAT are located:

• There are 15mm available.

Using an USB-cable with a 90-degrees rotated plug, it should fit. See attached images.

Probably, buying such cables, cutting and just using the two power-wires will be easier than soldering an additional cable onto the board of the HAT.

Hope you agree.

Cheers,

Hello Yvo,

maybe you can use something like this?

Hi Backdraft007

Thank you very much for the link.

Looks promising and worth a trial. A downside will be, that I will introduce an open connection more. Currently, I prefer to cut cables to avoid an addition, for humidity and vibrations, delicate connection.

Cheers,

Yvo

In the meantime, I found a hopefully suitable cable:

I will see, how it works.

Hey,

good luck. :)

Good find. Let us know how it goes.

I have used this cable so far, but it takes up too much space in my machines.

I will do. The cable is not on stock right now. But should be delivered by mid-December. Let's see.
