Please see image The image isn’t here. You can’t (I don’t think!) drag and drop images, you need to use the upload icon (7th from the left in the reply menu) to upload the image file. That said I can probably answer anyway. In Fritzing there are usually not active USB connections (the exception is USB plugs where the pins are broken out.) I expect you have a module that looks like this: ![capture](https://forum.fritzing.org/uploads/default/original/2X/3/3b75569e9b393bf2af85e3c310f708727dee8222.jpeg) (which I made for someone a few weeks ago.) You will note the red connection dots in the USB connector. That is where the input connection in schematic would go. In real life the USB connector would connect to a USB port via a USB cable, but that typically isn’t shown in Fritzing. There are some breadboard only USB cables that will “connect” (only in breadboard not in schematic or pcb views) to the non functional USB port on a RaspberryPI cpu for instance (or any of the other CPUs that have USB ports) in breadboard for documentation purposes. The part pictured above is available here: > [@Looking for these parts](https://forum.fritzing.org/t/looking-for-these-parts/13509/4): > > After I made this module, I read the sim800l manual. The sim800l under some circumstances can draw 2A and thus this power supply is not big enough. There are 2A boost modules readily available some even have Fritzing parts (the lm2596 for instance, which is recommended in the data sheet, is on core parts.) In any case here is the requested booster as it is made now. [0.9v-5V-booster-usb-output.fzpz](https://forum.fritzing.org/uploads/short-url/dLILHdPwDWdfg32h0eodi7qqp6H.fzpz) (6.3 KB) on to the GSM module. edit: Problem number2, the GSM module wants 4V not 5V Specific… as 0.9v-5V-booster-usb-output.fzpz . Hope this helps, if not ask again til I (or someone else) gets it right 🙂 . Peter --- _[View the full topic](https://forum.fritzing.org/t/i-need-help-with-usb-output-please/13582)._
