UART Interface Design For devices with 3.3V power supply, you can directly connect the device UART port with module UART port according to the illustration in Fig 12. Fig 12 Circuit diagram (3.3V) If your device is powered by 5V, you can refer to the circuit shown in Fig 13 or design your own circuit for power conversion. The value of resistor can be adjusted according to actual circuit design. 5.2. Power Supply Requirement

- 19 -

If an LDO is used to supply the module with 3.3V power, C1 capacitor can be considered to be used with 10u-22u; If a DCDC is used to supply 3.3V power, C1 capacitor can be considered to be used with 22uF. It is recommended to supply the module with power higher than 400mA to ensure enough power supply to the module and avoid power down during data transmission. The module is designed with 2x 3.3V pins. You can power the module with either pin or both pins. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:

(1) This device may not cause harmful interference, and

(2) This device must accept any interference received, including interference that may cause undesired operation. Note: This product has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This product generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this product does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

Reorient or relocate the receiving antenna. Increase the separation between the equipment and receiver. Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. Consult the dealer or an experienced radio/TV technician for help.
