Hi Peter,
Thank you so much for your reply. Actually, I bought the module from AliExpress https://www.aliexpress.com/item/10PCS-LOT-Mini360-DC-DC-Buck-Converter-Step-Down-Module-4-75V-23V-to-1V-17V/32582509989.html.
In this page, it provided the dimensions of the module which is identical to what you posted from ElectroDragon.

I believe that the Fritzing part of this module will be useful because of its low-cost and high efficiency.
