Connect this pin to the
1.8 V power supply by
using a 10 kΩ pull-up
resistor before the
module power-on, and
the module enters the
USB download mode.
Leave this pin floating
if it is not used.

Used for future
function expansion or
functions that are not
open to users. There
may be more than one
pin named
RESERVED, but it
does not mean that the
RESERVED pins have
the same function or
definition. Be sure to
keep the RESERVED
pins floating.
 Sub-models of the N58 module without GNSS:
Pin 9 and pin 10 of the N58 module can be used for the UART4 interface (pin 9 is used for UART4_TXD,
pin 10 is used for UART4_RXD, and the interface level is 1.8 V). Pin 89 of the N58 module can be used for
the ADC2 interface (ADC2 interface characteristics are the same as ADC1 interface characteristics ).
 Sub-models of the N58 module with GNSS:
Pin 9 and pin 10 of the N58 module are RESERVED pins and must be kept floating. Pin 89 is the 1PPS pin.
For details, see section 5.6.9 "1PPS."
