R7 and R8 (4.7 k

) are optional pull-up resistors for the SCLK and SDIO lines required only when using an I2C

bus. The size of pull-up resistor value will vary based on the number of devices, capacitance, and speed of the bus.

Placement location is not critical. Refer to the I2C specification for additional design information.
