I've been very pleased with EasyEDA thanks and have just got my latest set of PCBs from JLCPCB.
I'd like to include a [mini DC-DC buck converter module](https://www.ebay.co.uk/itm/382730576356) in my latest project.
Specifically, I'd like to have a block diagram of the device with the inputs and outputs in the schematic and then be able to place the equivalent module during the PCB design.
If there's an existing equivalent module then I can't find. So, what would I need to create to allow me to do this ?
Thanks
