SIM8200G module VBAT voltage range is 3.3V to 4.3V, the typical value is 3.8V.
All GPIO (including UART) pin levels of the SIM8200G module are 1.8V. Pay attention to match the
external master pin levels.
2.2.2 Jumper Interface Introduction
It mainly describes the interface with jumper selection or switch status. Please check the jumper selection
and switch status according to the actual situation during use.
1）Position “S” is the main power supply switch for EVB, and the power supply in the direction of ON is
turned ON, and the power supply in the direction of OFF is turned OFF.
Note

SIM8200G-EVB_User Guidelines_V1.01
www.simcom.com 13 /26
Figure 6 Power supply switch
2）Position “P” USB 2.0 channel selection: as shown in the figure below, the test points at the position “P”
on the SIM8200G TE board are used to select the USB2.0 signal. When using the USB interface of the
EVB board, please short-connect the yellow frame together, and use the TE version of the USB
interface ,please short-connect the red frame with each other.
Figure 7 USB 3.1/2.0 channel selection
3）Position “I” codec I2C jumper：The I2C signals of the audio codec need to add a jumper cap to the
position “I” on the EVB board. To use the audio function, you need to confirm whether the jumper at this
position is correct.
Figure 8 Codec I2C jumper

SIM8200G-EVB_User Guidelines_V1.01
www.simcom.com 14 /26
4）Position “I” for the I2C2 interface jumper of the sensor peripheral of EVB, Insert the jumper cap as
shown in the figure below, and you can also debug other peripherals here.
Figure 9 Sensor I2C jumper
5）Position “I”, the SPI interface of the EVB board needs to be jumpered according to the following jumper
to connect with the SPI FLASH on the EVB board; You can also connect other peripherals for debugging.
Figure 10 SPI jumper
6）Forced download point: Both TE board and EVB board, as shown in the following figure (in the yellow
frame), the two test points in the frame are shorted together and then powered on, and the SIM8200G
enters the download mode.
Figure 11 Forced download point

SIM8200G-EVB_User Guidelines_V1.01

7）Position “K” is a SLEEP switch.Turning to the side of the board triggers SIM8200G to enter SLEEP.
Turning to the side of the board triggers SIM8200G to wake up.
Figure 12 SLEEP switch
2.2.3 Antenna Interface Introduction
For detailed antenna design, please refer to the document SIM8200G_LGA Antenna Port Mapping and
Design Guide_V1.00；The antenna interface of SIM8200G is briefly described in the following picture and
