I am a heavy user of your Grove system, and I find it really awesome. Thanks.
I have recently been using your 3 Axis Digital Accelerometer(±16g) (https://wiki.seeedstudio.com/Grove-3-Axis_Digital_Accelerometer-16g/), and found an error in the product. The specific issue is that “INT1” and “INT2” are printed wrongly on the current version of your PCB (v1.3). I’m not aware of if you have a newer version of the board, but the current image on the webpage, and your schematics include the error.
Possible solution: The printed texts “INT1” and “INT2” should simply be switched.
Even though this might seem like a tiny issue, it put me on a few goose chases because I assumed that the printed text on the PCB was correct.
