LPWA Module Series
BG600L-M3 Hardware Design
BG600L-M3_Hardware_Design 21 / 83
1. PWRKEY output voltage is 1.5 V because of the voltage drop inside the Qualcomm chipset. Due to
platform limitations, the chipset has integrated the reset function into PWRKEY. Therefore, PWRKEY
should never be pulled down to GND permanently.
2. RESET_N is connected directly to PWRKEY inside the module.
3. ADC input voltage must not exceed 1.8 V.
4. The input voltage range of USB_VBUS is 1.3–1.8 V.
5. GPIO1 (pin 9), NET_STATUS (pin 47), GRFC1 (pin 63) and GNSS_LNA_EN (pin 66) are
BOOT_CONFIG pins, and please do not pull them up before startup.
6. Keep all RESERVED pins and unused pins unconnected.
7. GND pins should be connected to ground in the design.
