An interposer is a device that allows you to connect to the Ai Pin over ADB + USB. This unlocks the device for additional uses such as openPin's projects.
Note
Access over ADB requires the leaked Humane ADB cert. We cannot help you obtain this file.
We have two different endorsed mechanisms for obtaining an interposer:
This option is the recommended interposer solution due to its high quality and ease of construction. It does require fabrication of a PCB and fine SMD soldering ability.

This option is able to be built completely DIY (with the help of a 3D printer). It requires fine soldering ability, but less than that required by SMD components.
