To power the BG95M3LA-64-SGNS with a 127V AC power supply, you will need to step down the voltage to an appropriate DC level suitable for the module. The BG95 module typically operates from a DC supply voltage. Here's a basic outline of the connections required:
AC to DC Conversion:
Use an AC-DC converter or power supply module to step down from 127V AC to a suitable DC voltage (e.g., 5V, 3.3V).
Ensure the output current rating is sufficient for the BG95 module's requirements.
Power Connections:
Connect the output of the AC-DC converter to the BG95 module's power pins:
Connect the DC positive output to U1:VBAT_BB, VBAT_BB, and VBAT_RF.
Connect the DC ground to all GND pins on the BG95 module.
Basic Control Signals:
Connect U1:PWRKEY to a control circuit (e.g., switch or microcontroller GPIO) to power on the module.
Connect U1:~RESET to a reset circuit or microcontroller GPIO for resetting the module if needed.
Communication Interfaces (Optional):
If using USB, connect:
U1:USB_VBUS, USB_DP, and USB_DM to a USB interface.
If using UART, connect:
U1:MAIN_TXD, MAIN_RXD, MAIN_CTS, MAIN_RTS to a UART interface on your microcontroller or PC.
GNSS and RF Antenna Connections:
Connect an appropriate GNSS antenna to U1:ANT_GNSS.
Connect an RF antenna to U1:ANT_MAIN.
These steps outline the basic connections needed for the BG95M3LA-64-SGNS module. Ensure all connections are secure and that the power supply and communication interfaces meet the module's specifications.
