1 Introduction
This document defines the FC20 series module and describes its hardware interface which is connected with the customer’s application as well as its air interface.
The document can help customers quickly understand module interface specifications, as well as the electrical and mechanical details. Associated with application note and user guide, customers can use FC20 series module to design and set up mobile applications easily.
FC20 series module contains two variants: FC20 and FC20-N. Customers can choose the dedicated type basing on their requirements. The following table shows the entire models of FC20 series.
Table 1: FC20 Series Products
1.1. Safety Information
The following safety precautions must be observed during all phases of the operation, such as usage, service or repair of any cellular terminal or mobile incorporating FC20 series module. Manufacturers of the cellular terminal should send the following safety information to users and operating personnel, and incorporate these guidelines into all manuals supplied with the product. If not so, Quectel assumes no liability for the customer’s failure to comply with these precautions.
FC20_Series_Hardware_Design Confidential / Released 7 / 47
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, so as to prevent interference with communication systems. Consult the airline staff about the use of wireless devices on boarding the aircraft, if your device offers an Airplane Mode which must be enabled prior to boarding an aircraft.
Switch off your wireless device when in hospitals, clinics or other health care facilities. These requests are desinged to prevent possible interference with sensitive medical equipment.
Cellular terminals or mobiles operating over radio frequency signal and cellular network cannot be guaranteed to connect in all conditions, for example no mobile fee or with an invalid SIM card. While you are in this condition and need emergent help, please remember using emergency call. In order to make or receive a call, the cellular terminal or mobile must be switched on and in a service area with adequate cellular signal strength.
Your cellular terminal or mobile contains a transmitter and receiver. When it is ON, it receives and transmits radio frequency energy. RF interference can occur if it is used close to TV set, radio, computer or other electric equipment.
In locations with potentially explosive atmospheres, obey all posted signs to turn off wireless devices such as your phone or other cellular terminals. Areas with potentially explosive atmospheres include fuelling areas, below decks on boats, fuel or chemical transfer or storage facilities, areas where the air contains chemicals or particles such as grain, dust or metal powders, etc.

2 Product Concept
2.1. General Description
FC20 module is a low-power and low-cost wireless module based on QCA9377-3.
FC20 module supports 1×1 IEEE 802.11 a/b/g/n/ac WLAN standards and BT 4.1, enabling seamless integration of WLAN/BT and low-energy technology. FC20 supports a low-power SDIO 3.0 interface for WLAN and a UART/PCM interface for BT, and also supports LTE-WLAN coexistence and LTE-BT coexistence. The BT function of FC20 is under development.
2.2. Directives and Standards
The FC20 module is designed to comply with the FCC statements. FCC ID: XMR201703FC20 The Host system using FC20 should have label “contains FCC ID: XMR201701FC20
2.2.1. FCC Statement
Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.
2.2.2. FCC 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 as well as kept minimum 20cm from radio antenna depending on the Mobile status of this module usage. This module should NOT be installed and operating simultaneously with other radio. The manual of the host system, which uses FC20, must include RF exposure warning statement to advice user should keep minimum 20cm from the radio antenna of FC20 module depending on the Mobile status. Note: If a portable device (such as PDA) uses FC20 module, the device needs to do permissive change and SAR testing.
Any Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment.

FC20 Series Hardware Design
Note: This equipment 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 equipment 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 equipment 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 theequipment 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.
2.2.3. IC statement
This device complies with Industry Canada licence-exempt RSS standard(s). Operation is subject to the following two conditions: (1) This device may not cause interference, and (2)
This device must accept any interference, including interference that may cause undesired operation of t he device.
Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radio exempts de licence. L'exploitation est autorisée aux deux conditions suivantes:
(1) l'appareil ne doit pas produire de brouillage, et (2) l'utilisateur de l'appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage est susceptible d'en compromettre le fonctionnement.
The antenna(s) used for this transmitter must be installed to provide a separation distance of at least 20 cm from all persons and must not be collocated or operating in conjunction with any other antenna or transmitter, End-Users must be provided with transmitter operation conditions for satisfying RF exposure compliance.
Modular Approal: The FC20 module is designed to comply with the IC statement. IC ID is 10224A-201703FC20 . The host
system using FC20, should have label indicated it contain modular’s IC ID 10224A-201703FC20 .
This radio module must not installed to co-locate and operating simultaneously with other radios in host system , additional testing and equipment authorization may be required to operating simultaneously with other radio.
