Using 3 modules with SDA and SCL

Projects General Guidance
1

I want to use the following modules with an Arduino nano 5V:

Adafruit Si5351a - Adafruit Si5351A Clock Generator Breakout Board - 8KHz to 160MHz : ID 2045 : $7.95 : Adafruit Industries, Unique & fun DIY electronics and kits

Adafruit BMP180 - BMP180 Barometric Pressure/Temperature/Altitude Sensor- 5V ready : ID 1603 : $9.95 : Adafruit Industries, Unique & fun DIY electronics and kits

Adafruit DS1307 - DS1307 Real Time Clock breakout board kit : ID 264 : $7.95 : Adafruit Industries, Unique & fun DIY electronics and kits

All modules use SDA and SCL.

Will I have problems?

Do I have to change something in the Arduino code?

Thank you in advance

if they use SDA and SCL then they are I2C.
I2C works with adreses, I2C devices can have are Range/Fixed or all Adreses.

so some where in the product decription you should see which adress it uses.
this way you can hookup 128 differnt I2C modules with 2 wires :smiley:

That means "most likely, yes..."
