I2C devices are so commonplace nowadays that the hacker community has mostly coalesced around 2 connector types: JST SH and JST PH, known variously as Stemma, Qwiic, Stemma QT, Grove, etc. You can get an almost unlimited number of sensors and chip breakouts with these connectors, which can be daisy-chained for a large number of different sensors on the same bus. Well, this nifty I2C Shim for the Pico brings two JST SH connectors out for easy connection to Stemma QT/Qwiic peripherals.
The board is a nice, clean design. Staggered pads make for a tight, snug fit on the header pins coming from the Pico; however, you can also solder it directly to the Pico, or solder it to the header pins for a more secure, long-term connection. The board and connectors are slim enough that you could still mount the combination onto a PCB and solder the headers into place.
Having access to both I2C buses is a plus, as often you may want to connect two of the same sensor as many cannot have their I2C addresses reconfigured. This will allow you to do so without much hassle at all! If you use a lot of I2C peripherals, pick up a few of these and keep them with your hoard of Picos (come on, we all have a hoard of them) for quick and easy prototyping when needed!
