I2C Pins - Mcube MC3635 Quick Start Manual And Demo

MC3635 3-Axis Accelerometer

1.3 I2C PINS

• Connect the SCL (I2C clock pin) to your microcontroller's I2C clock line.
• Connect the SDA (I2C data pin) to your microcontroller's I2C data line.
R4, R5: If using I2C and I2C pull-up resistors are needed for your application then
install~4.7KΩ resistors into R4 (SCL clock pin) and R5 (SDA data pin) which are not
installed by factory default. In addition, besides soldering resisters on R4/R5, you can add
axial lead 4.7K ohm resistors to the SDA and SCL pin respectively. It will work the same
either way.
NOTE: DO NOT install more than one setup pull-up resistors per I2C bus.
