VDD33 is main power supply,The transmitting burst will cause voltage drop and the power supply must be able to provide sufficient current up to 700mA; VDD18 is for GPIO and can be supplied by modules VDD_1V8, the routing line of VDD18 needs to meet the width of at least 300mA current, and the parallel capacitance is not greater than 10uF; VDD_XTAL is for XTAL and can be supplied by SIM7600 series modules VDD_1V8. When all power are supplied W58 will work well together with SIM7600 series modules.

As its speed rate is too high, more sensitive to interference, so need routing GND protection, SDIO go online ground plane for the bottom of the need to continuously complete, and isometric and 50 impedance control, the length of SDIO bus should be no more than 8.4 cm long, online capacitance does not exceed 20pf, line spacing for the line width of 2 ~ 3 times, and other devices and lines near SDIO should keep 0.5 mm. In order to facilitate the commissioning of SDIO, the resistor between W58 and SIM7600 series modules can be concatenated with 0 ohms, and the resistance is close to W58.

Safety Caution and Statements Table 22Safety Caution Marks Requirements When in a hospital or other health care facility, observe the restrictions about the use of mobiles. Switch the cellular terminal or mobile off, medical equipment may be sensitive and not operate normally due to RF energy interference. Switch off the cellular terminal or mobile before boarding an aircraft. Make sure it is switched off. The operation of wireless appliances in an aircraft is forbidden to prevent interference with communication systems. Forgetting to think much of these instructions may impact the flight safety, or offend local legal action, or both. Do not operate the cellular terminal or mobile in the presence of flammable gases or fumes. Switch off the cellular terminal when you are near petrol stations, fuel depots, chemical plants or where blasting operations are in progress. Operation of any electrical equipment in potentially explosive atmospheres can constitute a safety hazard. Your cellular terminal or mobile receives and transmits radio frequency energy while switched on. RF interference can occur if it is used close to TV sets, radios, computers or other electric equipment. Road safety comes first! Do not use a hand-held cellular terminal or mobile when driving a vehicle, unless it is securely mounted in a holder for hands free operation. Before making a call with a hand-held terminal or mobile, park the vehicle. GSM cellular terminals or mobiles operate over radio frequency signals and cellular networks and cannot be guaranteed to connect in all conditions, especially with a mobile fee or an invalid SIM card. While you are in this condition and need emergent help, please remember to use emergency calls. In order to make or receive calls, the cellular terminal or mobile must be switched on and in a service www.simcom.com 31 / 35 W58 Hardware Design area with adequate cellular signal strength. Some networks do not allow for emergency call if certain network services or phone features are in use (e.g. lock functions, fixed dialing etc.). You may have to deactivate those features before you can make an emergency call. Also, some networks require that a valid SIM card be properly inserted in the cellular terminal or mobile. FCC Statement This device complies with part 15 of the FCC rules. Operation is subject to the following two condit ions: (1) this device may not cause harmful interference, and (2) this device must accept any interferenc e received, including interference that may cause undesired operation. Changes or modifications not expressly approved by the party responsible for compliance could void the users authority to operate the equipment. NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, p ursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates uses and can radiate radio fre quency energy and, if not installed and used in accordance with the instructions, may cause harmful inter ference to radio communications. However, there is no guarantee that interference will not occur in a part icular installation. If this equipment does cause harmful interference to radio or television reception, whic h can be determined by turning the equipment off and on, the user is encouraged to try to correct the inte rference 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. Important Note:

Radiation Exposure Statement This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with minimum distance 20cm between the radiator and your body. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. Country Code selection feature to be disabled for products marketed to the US/Canada. This device is intended only for OEM integrators under the following conditions:

1. The antenna must be installed such that 20 cm is maintained between the antenna and users, and 2. The transmitter module may not be co-located with any other transmitter or antenna, 3. For all products market in US, OEM has to limit the operation channels in CH1 to CH11 for 2.4G band by supplied firmware programming tool. OEM shall not supply any tool or info to the end-user regarding to Regulatory Domain change. (if modular only test Channel 1-11) As long as the three conditions above are met, further transmitter testing will not be required. However, the OEM integrator is still responsible for testing their end-product for any additional compliance requirements required with this module installed. Important Note:

www.simcom.com 32 / 35 W58 Hardware Design In the event that these conditions cannot be met (for example certain laptop configurations or co-location with another transmitter), then the FCC authorization is no longer considered valid and the FCC ID cannot be used on the final product. In these circumstances, the OEM integrator will be responsible for re-evaluating the end product (including the transmitter) and obtaining a separate FCC authorization. End Product Labeling The final end product must be labeled in a visible area with the following" Contains FCC ID: 2AJYU-8PY A00C". Manual Information to the End User The OEM integrator has to be aware not to provide information to the end user regarding how to install or remove this RF module in the users manual of the end product which integrates this module. The end user manual shall include all required regulatory information/warning as show in this manual. ISED Statement
