I’ve got this small 1-row drone case now, which I wanted to power without a normal power module, as those take up precious rack space. After a quick discussion on our AEM Discord chat, I simply tried to connect a normal USB power bank to the case’s 5V and GND side link connectors, and so far it seems to work without issues:  My plan would be to make a small adapter, for example from mini or micro USB to the side connector pin header, which could stay attached to the case and enable me to plug a common USB cable into it. A question to robertlanger would be, if such an adapter could be made “properly” by tangible waves and offered in the web store, for people with small cases - although I’d assume you could even power a bigger system from a USB power bank. Of course I might have missed something and/or just gotten lucky with my three modules here, and USB 5V are actually not a good power supply? |

That looks indeed like a simple job for a 3d printer, it can't be too difficult to make a simple enclosure in tinkercad.

Tiny morning DIY project: View AttachmentView AttachmentView AttachmentIdeally there would be a little enclosure around the adapter now, but I don't know what to use for that at the moment. I guess a 3D printer would be useful, but maybe a black piece of Scotch tape will also do the trick  View AttachmentVey nice micro mini nano diy. Not exactly obvious on your picture, would you mind sharing a scematic of this circuit ? Thanks |

Not exactly obvious on your picture, would you mind sharing a scematic of this circuit ? Sure, it’s very simple:  I just connected the USB and AE Modular pins (GND to GND, 5V to 5V) and added a 104 (100nF) capacitor in between for smoothing. EDIT: Here’s the AE Modular pinout.  EDIT 2: As usual: DO IT AT YOUR OWN RISK! So far it works for me and my tiny case with three modules, but I haven’t tested this much yet. |

I might just screw the thing to my case using the two mounting holes on the microUSB socket and then tape over it. |

Hello and bravo !! Was asking me if we could just use the two +5V and ground wires directly from the USB cable, cutting it's male socket, stripping it... and forgetting about the data wires. Maybe there should be No need for pcb or Usb socket ? I had once to repair a Usb power (no data involved) and got into that kind of solution : Maybe it Would'nt be hard to add the capacitor, and a 5 pin socket that would fit to the case ? Do you think it could be dangerous?
Thanks

I chose an adapter however, because it can stay attached to the case and I always carry a micro USB cable with me and generally have lots of them for various devices. This means that I will always have the right cable around. If I built a USB power cable specifically for the AE Modular, I’d only have one cable that I’d need to keep track of  |

This is so true for the cables !! Also the little PCB can help in case of "cable-stress" .. you would'nt break the pins of the Ae case !!

Made one and it works perfectly. Thank you Felix! Used some foam tape and washy tape to secure the back and make sure I don't short the pins when connecting or moving. Much easier than plastids and I hate electrical tape as it the glue usually starts to break down and slide around leaving gunk on your hands. I have a mini case on the way so this will be really useful for testing DIY stuff without any danger of harming anything else in my larger system.    |
