1. Overview
This article defines the Lierda NB-IoT module, and describes its hardware interface, application
methods, etc.
This article can help you quickly understand the standard of module interface, as well as the
electrical and mechanical characteristics. Combined with other relevant documents, you can
quickly learn how to use the NB-IoT module.
This document NBXX-01 on behalf of NB05-01, NB08-01 collectively referred to these two
models.
2. The introduction of the Module
The purpose of the NBXX-01 module is to use the NB-IoT broadcast protocol (3GPP NB-IoT
Rel-13) with mobile network operator communications infrastructure equipment. The band used
by the NB-IoT module below.
NBXX-01 series modules used in the band:
Mode NB05-01 NB08-01
H-FDD B5(850MHZ) B8(900MHZ)
The NBXX-01 module dimensions of 20mm × 16mm × 2.2mm, the module can meet almost all
the requirements of the Internet of Things applications, including vehicles and personal tracking,
security systems, wireless POS, industrial PDA, smart metering, remote maintenance and
control, Smart city and more.
NBXX-01 module is LCC package, is a SMD type module, it can be easily embedded in the
application circuit.
NBXX-01 module is designed with energy-saving technology, ultra-low power consumption in
sleep mode.
This module is fully in line with the EU RoHS directive.

6.2 Operating mode
The NBXX-01 module has three modes of operation to determine the different levels of low
power consumption based on usage scenarios. Under normal operating conditions are divided
into:
Active mode The module is active; all functions are normally available for
data transmission and reception; the module can switch to Idle
mode or PSM mode in this mode.
Idle The module is in a light sleep state, the module is in a network
connection state and can accept paging messages. In this
mode, the module can be switched to active mode or PSM
mode.
PSM Module only RTC work, the module is in the network is not
connected, no longer accept paging messages. When DTE
(Data Terminal Equipment) actively send data or timer T3412
(periodic update) timeout, the module will be awakened.
