5.1.2 VDD_
1P8
The VDD_1P8 power supply is steady on and cannot be turned off even in the sleep state. If an external circuit is
connected, power consumption in sleep mode will be increased. It is recommended that VDD_1P8 should be
used only for level shifting and ESD protection should be added.
The VDD_1P8 pin of the N58 module can provide 1.8 V voltage output, and the maximum output
current is 50 mA.

5.2.1 PWRKEY_N
There are three startup control methods for the N58 module. You can choose to use a method based on a specific
application scenario. If necessary, contact Neoway FAE for confirmation.
The N58 module allows startup by the following controls:
Module startup controlled by button, as shown in Figure 5-6
Module startup controlled by MCU, as shown in Figure 5-7
Automatic startup once powered on, as shown in Figure 5-8
