I have an arduinoboy that is powered via the dmg link cable...

I now have a GBA I wanted to use with it... I assumed using the gameboy pocket MGB-004 adapter cable would work to connect the GBA to the DMG ended lead from my arduinoboy... it doesn't - no power!

anyone know if this is because:

a) the adapter doesn't pass the power?
b) GBA link cables in general never provide power at all.
c) another reason?

trying to work out if I need to build another arduinoboy (which I was halfway to doing already) with external power OR just solder a new lead....

thanks!

All of the aftermarket GBC link cables I have seen have the power line connected but it connects to SD on the other side. So if you cut a link cable, you can wire in the power lead.

I'm not sure about the MGB-004 adapter but I'd guess it will work (in fact I swear I've tested it and confirmed that). A quick test with a multimeter should confirm it pretty quick though!

You got me, I was being a bit lazy wink

Thanks really useful to know the GBA should be providing power at least as I've modded it so possible I've caused some calamity there.

Yep, I know for a fact that all GBAs have power on the link port, I use it for the GBA Midi Synth: https://catskullelectronics.com/gbamidi

But yeah some link cables are wired funky which is why I include one in that bundle.

oh, of course. d'oh, I have one of those. Logic obviously not my strong point today.

i'll get busy with the multimeter and work out what's going on.

thanks!
