The module power supply range is 3.3 - 4.2V, and it is recommended to use 3.7V/2A power supply.
- Page 8 In order to prevent the damage of the module caused by surge and overvoltage, it is suggested that a 5.1V/500mW zener diode to be connected on the module VBAT pin. It is suggested that 3 ceramic capacitors (33pF, 10pF, 100nF) to be added to the VBAT pin and to be placed close to the VBAT pin.
- Page 9 3.5 UART port The module provides a UART port, the serial port level is 1.8V. The AT command can be sent through the serial port, print program log information, etc. The module serial port supports 9600/19200/38400/57600/115200/230400bps baud rate and defaults is 115200bps.
