Power supply, Axocontrol & DIN5 only

[kx3]

Sorry if this has been anserwed but I can't find the answer ...

I want to use my AXOControl as a DIN5 controller only (nothing plugged in any usb port, processor barely used as it only serves as 10 midi out objects computing).
Is 7.5v / 0,150 Amp enough? (1.125 watt)

If not (and assuming 7.5v) what is the lowest current that will work?

Thanks

according to this post from @johannes 150mA @7.5V might be a bit too low even for a bare axoloti, axocontrol will be a good bit higher with the UI stuff.

Power Supply for stand alone use

The DC barrel jack input uses a switching power supply, allowing a wide input voltage range and is capable of powering a USB device connected to the USB host port that consumes 500mA (the legal maximum for USB). Any supply between 7V and 15V is fine, the current it needs to deliver depends on what you plug into the USB host port. Rough ballpark figures: at 7V, 700mA is fine, at 15V, 250mA is enough. Center pin positive. DC-plug center diameter should be 2.1 mm. (there is also a 2.5mm plug varian…

but iiuc not much to loose with trying an underpowered supply?

also when you say DIN5 do you actually mean the mini connector or just plain old MIDI DIN? https://pinouts.ru/Audio-Video-Hardware/minidin_to_din_pinout.shtml

Yes, I mean the old standard MIDI connector. The board doesn't have to provide power to external USB device, neither receive power from usb port
