2.1mm to 1.7mm DC jack adapter

Some boards have really compact DC barrel jacks, like the PD Power Extension Board for Raspberry Pi 5. These 1.7mm barrel jacks aren't common so finding a suitable power supply can be tricky.

This adapter turns your tiny 1.7mm DC jack into the much more common 2.1mm barrel jack format, opening up your power options.

You can use this adapter for anything else that has a 1.7mm DC jack, such as a an old PSP.
