Hello,
I've followed the hookup guide for I2C as outlined here:
https://learn.sparkfun.com/tutorials/ad ... okup-guide
It involves using 2x 4.7k resistors, and this works just fine. However, the board has two components that look suspiciously like resistors already built-in. My questions are as follows:
1. Do some versions of the ADXL345 board come with built-in 4.7k resistors?
2. If yes, can I ignore the diagram that says to use external resistors for the SDA and SCL lines?
Thanks!
N.
