3.3V 146 VREF PO Reference voltage Output voltage 1.8V 1.8V The C10GS module is powered by a single power supply and the module provides six power supply pins. The power supply range is from 3.6V to 4.5V. It is recommended to use 3.8V/1.1A power supply. If the module's operating voltage drop causes the VCC supply voltage to be too low or the supply current is insufficient, the module may shut down or restart. Therefore, in order to reduce the power fluctuation of the module when working, it is necessary to use a low-ESR value of the voltage regulator capacitor, the power pin and the ground pin should be connected and can provide sufficient power supply capability. Under the premise of ensuring that the VCC power supply is sufficient, one 22uF tantalum capacitor can be connected in parallel with the power input, 10uF in parallel, two 0.1uF capacitor (eliminating clock and digital signal interference) and 33nF (eliminating low frequency RF interference) ceramic capacitors. Figure 3 VCC power supply www.cavliwireless.com 22 C 10G S Hardware Manual 3.3.2 Power reference circuit In actual design, the power circuit can be designed using a switching DC power supply or a linear LDO power supply, and then the PMOS transistor is used to control the power supply input so that the power supply can be completely cut off. Both design circuits need to supply enough current. Specific reference to the following circuit design:
Figure 4 DC switching power supply reference circuit Figure 5 PMOS tube control power switch reference circuit www.cavliwireless.com 23 C 10G S Hardware Manual NOTE To prevent damage to the module from surges and over voltages, it is recommended to connect a 5.1V/500mW Zener diode to the VCC pin of the module. It is recommended to add 3 ceramic capacitors (33pF, 10pF, 100nF) to the power pin input and place them near the VCC pin. The minimum operating voltage of the module is 3.6V. Data transmission or calls will generate a current of more than 2, thus a ripple voltage drop will occur on the power supply voltage. Therefore, the actual supply voltage must not be lower than 3.6V. Due to the large current consumption of the module power pins, it is recommended that the PCB traces be as short as possible. Minimize the equivalent impedance of the VCC trace. 3.3.3 VREF 1.8 voltage output The C10GS module outputs 1.8V through VREF for internal digital circuitry. This voltage is the logic level voltage of the module. After normal power-on, the 146th pin will output 1.8V and the current load will be 50mA. The external master can read the voltage of VREF to determine if the module is powered on. VREF can also be used as an external power supply, such as a level shifting chip, but maximum load should be within 50mA. 3.4 Switching machine reset mode 3.4.1 Turn ON Module The 142th pin of the C10GS module is POWER_ON pin. The module can be powered on by pulling down POWER_ON active low for at least 500ms. The user can check whether the module is powered on by querying the high and low levels of the VREF pin. Table 3-4 Switch pin definition Pin No. Signal name 142 POWER_ON I/O PI High value Description Power on It is recommended to use the open-collector drive circuit to control the POWER_ON, which can be released after the base level is pulled for 500ms, and the module is powered on. www.cavliwireless.com 24 C 10G S Hardware Manual Figure 6 Power-on reference circuit Switching machine design can also be done with buttons, button accessories need to be placed with a TVS tube for ESD protection. Figure 7 Power-on reference circuit-2 3.4.2 Reset control The C10GS module Pin 145 is a reset pin. The application detects that the module is abnormal. When the software does not respond, the module can be reset. Pull the pin low for 100-450ms to reset the module. The RESET pin is sensitive to interference. A 10nF to 0.1uF capacitor can be installed near the signal for signal filtering. Keep away from RF interference signals when routing. www.cavliwireless.com 25 C 10G S Hardware Manual Figure 8 Reset reference circuit Table 3-5 RESET pin parameters Symbol Treset VIH VIL Description Low level pulse width RESET input high level voltage RESET input low level voltage Min 150 1.4

Detailed instructions can be found in the C10GS AT Command Set Manual. 3.5 U SB interface The C10GS module USB interface supports USB2.0 high-speed protocol, supports slave mode, and does not support USB charging mode. USB input and output traces must comply with the USB2.0 feature. The input power supply of USB_VBUS is 3.3 - 5V. The USB interface is used to update the firmware of the module. It is recommended to use USB interface for the firmware update.

USB interface application reference circuit is as follows Figure 9 USB connection design circuit diagram NOTE R1 or R2 is required to have a resistance of 16R The USB interface supports high-speed (480Mbps) and full-speed (12Mbps) modes, so the trace design needs to strictly follow the USB2.0 protocol requirements, pay attention to the protection of the data line, differential trace, control impedance is 90. In order to improve the antistatic performance of the USB interface, it is recommended to add an ESD protection device on the data line. The equivalent capacitance of the protection device is less than 2pF. The USB interface bus supply voltage is provided internally by the module and does not need to be externally supplied. At the same time, since the USB interface of the module does not provide USB bus power, the module can only be used as a slave device of the USB bus device. www.cavliwireless.com 27 C 10G S Hardware Manual 3.6 U ART interface The C10GS module provides three sets of UART interfaces.

Users need to design a USIM card slot on their own interface board. The USIM card interface reference circuit is as follows Figure 12 USIM design circuit diagram www.cavliwireless.com 31 C 10G S Hardware Manual NOTE The USIM interface cable is recommended to use ONSEMI's SMF15C device for ESD protection. The peripheral circuit components should be placed close to the card holder. The SIM card holder is close to the module layout. The USIM card circuit is susceptible to radio frequency interference and does not recognize or drop the card. Therefore, the card slot should be placed as far as possible from the RF radiation of the antenna. The card trace should be as far away as possible from the RF, power supply and high-
speed signal lines. The USIM_DATA has been internally pulled up to VREF through a 10K resistor, and no external pull-up is required. USIM_DETECT is the USIM card insertion or non-insertion detection pin. It is high by default. The SIM card status can be detected by this PIN during hot plug application To avoid transient voltage overload, the USIM interface requires a 22R resistor in series with each other on the signal line path. The ground of the USIM deck and the ground of the module should maintain good connectivity. 3.8 G eneral purpose G PIO interface The C10GS module contains thirteen general purpose control signals.

The maximum output current of the module power supply VDD_SD is 400mA. The reference voltage for VDD_SDIO is 3.3V, if the Bluetooth and Wi-Fi module is of 1.8V a translator is required. SD card clock frequency is up to 200MHZ. SDIO bus is a high-speed signal line and the characteristic impedance of the PCB design needs to be controlled at about 50 . The length of the signal line should be less than 25mm, and the distance between the signal lines should be 2 times the line width, and the ground should be as far away as possible from other possible interference lines. The SDIO signal line needs a 0 resistor in series to facilitate signal quality adjustment. In order to ensure good ESD performance, it is recommended to add a TVS tube to the SD card pin and place it near the pin. 3.13 Antenna The C10GS module provides two antenna interfaces, one main set antenna interface, which is responsible for the CAT 1/4 signals of the transceiver module, and another GNSS antenna interface. The GNSS antenna interface is L1. The impedance of the antenna interfaces are 50 . Table 3-18 Antenna interface pin definition Pin No. Signal name I/O Description Remarks 3 LTE_MAIN IO Main antenna interface 50 characteristic impedance 33 GNSS_L1 AI GNSS L1 antenna interface 50 characteristic impedance The pin-3 of the C10GS is the main set antenna interface. To facilitate the debugging of the antenna, a -type matching circuit needs to be added to the main board, and a 50 impedance line is taken. The pin 33 of C10GS is the GNSS antenna interface. The C10GS has a dedicated antenna L1, it supports GPS, GLONASS, BEIDOU, QZSS, SBAS and Galileo. In order to facilitate antenna debugging, a -type matching circuit needs to be added to the motherboard and a 50 impedance line is used. Recommended circuit is shown below www.cavliwireless.com 38 C 10G S Hardware Manual Figure 17 Main antenna matching circuit Figure 18 GNSS Passive antenna matching circuit Figure 19 GNSS active antenna matching circuit The C10GS module provides two RF antenna interfaces, which are the main set antenna and the GNSS L1 antenna. The antenna interface must be a 50 characteristic impedance trace. www.cavliwireless.com 39 C 10G S Hardware Manual The LTE_MAIN antenna is distributed reasonably to improve the receiving sensitivity. In actual use, the antenna board can be debugged and optimized according to the user's circuit board. Antenna impedance traces need to be away from digital signal lines, power supplies and other interference signals. The antenna impedance traces need to be three-dimensionally packaged, and the ground holes are added on both sides of the trace to isolate. 3.13.1 RF trace reference The main set of the C10GS module are extracted by pad. The antenna pad to the antenna feed point must use microstrip lines or other types of RF traces. The characteristic impedance of the signal line should be controlled at 50. The impedance of the RF signal line is determined by the material's dielectric constant, trace width (W), ground clearance (S), and reference ground plane height (H). Therefore, the RF trace requires an impedance simulation tool to calculate the impedance of the RF trace.

The USB port needs to add TVS on VDD, D+, D- for protection, and the TVS parasitic capacitance on D+/D- is <2pF;
The module's USIM card external pin needs to be protected by TVS, and the parasitic capacitance requirement is <10pF. The PCB layout of the protective device should be as close as possible to the "V" line to avoid the "T"
line. The ground plane around the module guarantees integrity and should not be split.
