    Never use a diode to make the drop voltage between a higher input and module power. Otherwise, Neoway will not provide warranty for product issues caused by this. In this situation, the diode will obviously decrease the module performances, or result in unexpected restarts, due to the forward voltage of diode will vary greatly in different temperature and current.

  • Page 22: Power-On/Off Control And Procedure

    If the module adopts a fixed baudrate, an unsolicited message ( ) will be sent to \r\nMODEM:STARTUP\r\n host through UART port, indicating that the module is initialized and the UART can respond to the AT commands. Copyright © Neoway Technology Co., Ltd.

  • Page 23: Figure 3-7 Power-On Procedure

    While the module is on, pull the ON/OFF pin to ground for at least 500 ms and then release, the module will try to detach to network and normally 2 seconds later it will shut down. Another approach to turn off the module is using AT commands. For details, please refer to Neoway_N10_AT_Commands_Manual. Copyright © Neoway Technology Co., Ltd.

  • Page 24: Figure 3-8 Power-Off Procedure

    The module keeps monitoring the voltage at VBAT. When it is lower than 3.3 V, the module shuts down automatically.
