11.5kbps. External interface is 1.8VCMOS level signal, which could be used for upgrade, port communication, etc. When using MG3732 module’s UART port to communicate with PC or MCU, please pay attention to the direction of TX, RX. It’s specially noted that MG3732 module’s UART port only supports 1.8V, therefore for non 1.8V external UART, it needs to convert the level. -
Page 20: Audio Interface
MG3732 module The module supports 2.85V/1.8V UIM card, and it’s strongly recommended to add ESD component to protect UIM card as shown in figure 4-2. Figure 4-2 UIM Card Circuit Reference Design Diagram Note: The clock data rate of UIM card circuit is 4M, and the card socket should be laid closely around the module and the wiring should be as short and thick as possible. -

Page 26: Module's Fixing Method
MG3732 module 5.3 Module’s Fixing Method The module’s fastening method adopts direct manual soldering to avoid second-time soldering. It’s strongly recommend to use the manual soldering because MC3732 module board is just 0.8mm thick and QSC6270 BGA space is too small. The second-time soldering would cause the melting of soldering tin and lead to short circuit of QSC6270 main chip, such as USB disconnected, large current, etc. - Page 27 MG3732 module all other operating configurations, including portable configurations with respect to 2.1093 and different antenna configurations. Maximum antenna gain allowed for use with this device is 2 dBi. When the module is installed in the host device, the FCC ID label must be visible through a window on the final device or it must be visible when an access panel, door or cover is easily re-moved.
