The power input range is from 3.3V to 4.5V, and the recommended value is 3.8V. The performance of the VBAT power, such as load capacity, and ripple size, etc., will directly affect the performance and stability of the module. In extreme cases, the modules operating current can reach 2A, and if the power supply capacity is insufficient, the voltage will drop. If the power voltage drops below 3.3V, the module may be powered off or restarted. 3.2.1 Power Supply The SC806 module needs to be powered by the VBAT_BB/VBAT_RF pin Table5Power supply parameters Parameters Minimum Recommended Maximum Unit VBAT_BB/VBAT_RFDC 3.3 3.8 4.5 V The copyright of this document is owned by Fibocom Wireless Inc., and the document shall not be replicated without approval.

SC806Hardware User ManualPage27 of 70 Figure 4Power Voltage Drop Example To ensure that the power voltage is not lower than 3.3V, it is recommended to connect two 220F tantalum capacitors with low ESR and filter capacitors of 1uF, 100nF, 39pF, and 33pF in parallel to the VBAT input of the module. It is recommended that the PCB trace of VBAT be as short and wide as possible. Reduce the equivalent impedance of the VBAT trace to ensure that at maximum output power, significant voltage drop will not occur at high currents. It is recommended that the width of the VBAT trace should not be less than 2mm, and the longer and the wider the trace, the ground plane of the power section should be more complete. 3.2.2 Lithium Battery Charge and Battery Management If the SC806 is powered by a battery, it uses a lithium battery with temperature detection function. The SC806 has a battery temperature detection function. The battery requires internal integration of a thermistor (default is 47K1%, B=4050 NTC), and the battery temperature detection pin is connected to the BATT_CON_TEMP pin (PIN 134). SC806 has built-in linear charge management circuit that supports the charge of 3.7V lithium battery, and the use of standard charger and non-standard charger for charge, with software automatic identification, standard charger maximum charge current 1.44A, and non-standard charger limited charge current less than 500mA. The charge process includes trickle charge, constant current charge, and constant voltage charge. Trickle charge: it is divided into two parts. Trickle charge-A: charge current 90mA when the battery voltage is lower than 2.8V; trickle charge-B: charge current 450mA when the battery voltage is between 2.8V~3.2V;

Constant current charge: constant current charge when the battery voltage is between 3.2V~4.2V. The current is 1.44A when adapter is charging. The current is t 450mA when USB is charging;

Constant voltage charge: constant voltage charge when the battery voltage reaches 4.2V. The charge current is gradually reduced, when the charge current is reduced to about 100mA, the charge is cut off. 3.2.3 RTC Power VRTC is the power supply for the internal RTC clock of the module and can be used as a backup power for the RTC clock. When the module power VBAT is powered on, the VRTC will output voltage. When there is no VBAT, The copyright of this document is owned by Fibocom Wireless Inc., and the document shall not be replicated without approval.

If the application scenario and the recommended design do not meet the requirements, please contact our technical personnel for confirmation. 6 RF PCB Layout Design Guide For user PCB, the characteristic impedance of all RF signal traces should be at 50. In general, the impedance of the RF signal trace is determined by the dielectric constant of the material, the trace width (W), the ground clearance (S), and the height of the reference ground plane (H). The control of the characteristic impedance of the PCB is usually in two ways: microstriptrace and coplanar waveguide. To illustrate the design principles, the following figures show the structure design of microstriptrace and coplanar waveguide when the impedance trace is at 50. Microstriptrace complete structure Figure 15Two-layer PCB Microstrip Structure Coplanar waveguide complete structure The copyright of this document is owned by Fibocom Wireless Inc., and the document shall not be replicated without approval.

The impedance simulation tool should be used to accurately control the RF signal trace at 50 impedance. The copyright of this document is owned by Fibocom Wireless Inc., and the document shall not be replicated without approval. SC806Hardware User ManualPage51 of 70 The GND pin adjacent to the RF pin should not have thermal welding plate and should be in full contact with the ground. The distance between the RF pin and the RF connector should be as short as possible. At the same time, avoid the right-angle route. The recommended route angle is 135 degrees. When connecting the device package, it should be noted that the signal pin must be kept away from the ground. The reference ground plane of the RF signal trace should be complete; adding a certain amount of ground holes around the signal and the reference ground can help improve the RF performance; the distance between the ground hole and the signal trace should be at least 2 times the line width (2*W). 7 WIFI and Bluetooth 7.1.1 WIFI overview The SC806 module supports 2.4G single-frequency WLAN wireless communication and 802.11b, 802.11g, and 802.11n standards, with a maximum speed up to 150 Mbps.
