I2C gadgets are so commonplace these days that the hacker neighborhood has principally coalesced round 2 connector varieties: JST SH and JST PH, identified variously as Stemma, Qwiic, Stemma QT, Grove, and so forth. You may get an nearly limitless variety of sensors and chip breakouts with these connectors, which will be daisy-chained for a lot of completely different sensors on the identical bus. Effectively, this nifty I2C Shim for the Pico brings two JST SH connectors out for straightforward connection to Stemma QT/Qwiic peripherals.
The board is a pleasant, clear design. Staggered pads make for a decent, comfortable match on the header pins coming from the Pico; nevertheless, you can even solder it on to the Pico, or solder it to the header pins for a safer, long-term connection. The board and connectors are slim sufficient that you possibly can nonetheless mount the mixture onto a PCB and solder the headers into place.
Accessing each I2C buses is a plus, as usually it’s possible you’ll need to join two of the identical sensor as many can not have their I2C addresses reconfigured. It will permit you to take action with out a lot problem in any respect! If you happen to use lots of I2C peripherals, choose up just a few of those and hold them together with your hoard of Picos (come on, all of us have a hoard of them) for fast and straightforward prototyping when wanted!
