This guide offers a comprehensive overview of the SIM7600CE module, detailing pin configurations, power management, and communication setup essential for integrating with Arduino projects.
NOTE
- Occupied Pins: D0, D1, D12. Pin D12 has been connected to the SIM7600CE power switch. You can set the pin HIGH/LOW to turn the module ON/OFF in code.
- SIM7600 on-board MIC shares the same channel with 3.5mm SIM7600CE microphone interface.
- Boot–power switch, short-press 1s to start the module and long-press 3s to shut down it.
- Indicator “ON” –SIM7600CE power indicator. The module will work properly only when it is powered by the external power supply.
- Net–GSM Signal Indicator:
- On: searching for network
- Flash Quickly(1 time per second): network registering is done.
- Jumper Cap Interface:
- RX/TX–SIM7600CE communication serial port, control via AT command.
- D0/D1&D7/D8–select the corresponding interface to communicate with SIM7600CE according to the Arduino controller you used.(For AT test)
- RI–Normally RI will keep high level until certain conditions such as receiving SMS, or a URC report coming, and then it will change to low level. It will stay low until the host controller clears the interrupted event with “AT+CRIRS” AT command.
- DTR–DTR pin can be used to wake SIM7600CE from sleep. When SIM7600CE enters sleep mode, pulling down DTR can wake SIM7600CE.
- FT–Low Level: Flight mode; High Level: Normal mode
