Reference Schematic Design for I2C

Figure 4-2: Reference Schematic Design for I2C
Notes:
1. Ferrite bead L1 is added for power noise reduction. Use one with an equiv-
alent impedance (600
2. Place C1 and C2 decoupling capacitors as close to the module as possible.
3. Pull high resistors R3 and R4 can be modified based on system application
for I2C.
4. The INT pin of module connect to MCU's INT pin (INT_H: data is ready for
MCU to access; INT_Low: data transfer is finished).
