Yep this module does not have pullups on SCL and SDA you need to provide those for i2c to work. I think you had mentioned the Arduino working with this but it has weak internal pullups enabled. I recommend using 4.7k resistors if you can, but quite a range will work with most devices. https://learn.sparkfun.com/tutorials/i2c/i2c-at-the-hardware-level -- This is an automated message from the Apache Git Service.
