  • I use this in the surface mount package, and would love a US supplier! Once I learned to hand-solder SOIC’s, DIP’s are just too big.

  • Thanks for the diagram, I had actually guessed within .05 from the helpful rulers in the product photo. I will give Eagle a try for my next round of designs.
    The PicAxe-based system I’m designing will have other 5V I2C devices on the same bus, so the lines are tied to 5V with 10K resistors. A 75 cent PCA9306 seems like an easy solution from my hobbyist perspective.
    BTW I’d buy PicAxe 28x2’s from you if you stocked the SMD version.

  • 1) When connecting a 3V device to a 5V I2C bus, is it necessary to use a level-shifting device such as a PCA9306?
    2) Pardon my noob question, but is there a footprint for this breakout board other than the Eagle file that I can’t read? I’d like to know where the mounting holes are so I can design a carrier board before buying one.

No public wish lists :(
