1 Functional description

1.1 Product overview

The ERF3000 Arduino shield is a series of LTE Cat.M1/Cat.NB1/EGPRS module offering a maximum data rate of

375kbps downlink and uplink. It features ultra-low power consumption, and provides pin-to-pin compatibility with an

Arduino UNO. The ERF3000 Arduino shield is also available with the Quectel LTE module EG91/EG95, Cat.NB1 (NB-IoT)

module BC95, UMTS/HSPA module UG95/UG96 and GSM/GPRS module M95.

A rich set of Internet protocols, industry-standard interfaces (USB/UART/I2C/Status Indicator) and abundant

functionalities (USB drivers for Windows XP, Windows Vista, Windows 7/8/8.1/10, Linux and Android) extend the

applicability of the module to a wide range of M2M applications such as wireless POS, smart metering, tracking, etc.

The ERF3000 combines the Power of the BG96 with an easy to use Arduino platform and allows for rapid testing an

development.

2 Interfaces

2.1 Power

Module supply input

The ERF3000 shield must be supplied through the VCC pins by a DC power supply with nominal voltage of 5V to 12 V.

Voltage must be stable during module operation, taking into account that the current drawn from VCC pins may vary

significantly based on the power consumption profile of the NB-IoT system.

Digital I/O interfaces supply output (V_INT)

The ERF3000 shield provide an internally generated supply rail output (V_INT) operating at 1.8 V. This can be used in

place of an external discrete regulator to supply external digital interfaces. The voltage level present at the V_INT pin

depends on the module operating mode:

- In the deep-sleep mode the voltage level is kept “Low” (i.e. 0 V)

- In active and connected modes the voltage level is maintained “High” (i.e. 1.8 V)

2.2 Antennas

The ERF3000 uses 2 antennas , 1 GPS antenna and 1 GSM antenna.

The GPS antenna is integrated on the PCB but also an external GPS antenna can be used by connecting it to the U.fl

connector. And the GSM antenna needs to be connected to the SMA of U.fl connector.

It is important to note that the antennas can’t be too close to one another, because they will cause interference. This

causes problems when using the GPS function of the shield.

2.2.1 GPS_ANT

The GPS antenna has been tuned with a LC Chebyshev filter to gain optimal performance.

The center frequency is around 1575 MHz.

2.2.2 GSM_ANT (ERF4041 GSM antenna)

The ERF4041 antenna is a black GSM antenna a SMA Male connector. The antenna can be used in the frequency band

of 800~840 / 1640 / 2200~2230 / 3410 MHz. The antenna can be used for applications , GSM , M2M and more.

For more information see ERF4041 datasheet

2.3 System function

On the Shield are 3 important power headers, the PWR header , the Level shift header and the USB PWR header.

These headers are marked with a red box on the following picture.

_________________________________________________________________________________________________



Option 1 and 3 are not recommended because the USB can’t supply enough power for some functions of the BG96

module on the shield. this may cause damage to the shield or to your USB power supply.

2.4 Status LED’s

The shield also has 3 LED’s to give an indication of the status of the shield.

Led Color State Description PWR Green Always on Shield is powered

Always off Shield is not powered

Stat Red 0.2s on/1.8 off Searching for network

1.8s on/0.2s off Idle mode

0.125 on/0.125 off Data transfer is ongoing with GSM/3G/4G network

Net Yellow Always on Registered to 3G network(UC20) Registered to 4G network(EC20)

Always off Others

2.5 SIM interface

To register and connect to a network a SIM card needs to be inserted and activated.

When a activated SIM is inserted, the correct APN must be set using AT commands.

Rework

2.7 Programming the shield

There are 2 ways to program the ERF3000. The first and most easy way is to use the Qnavigator software developed by

Quectel. In this software you can send AT commands via the PC. The second way to program the shield is via an

Arduino. if you choose to program the shield via an Arduino you can add your own custom sensors and build your own

application.

2.7.1 Programming the shield via Qnavigator

Before connecting anything first check if the headers are in the correct position. The Vin header should be on PWR if a

power adapter is being used. When this is the case, remove the USB PWR header. If no power adapter is used, set Vin

on 5V and connect the USB PWR header.

Now connect the USB cable to the device and to the PC. The green LED will light up. Now press the Power switch for 3

seconds. The Stat LED should light up and the Net light should start blinking.

Now the correct drivers need to be installed on your PC. These can be found here

Also the Qnavigator software needs to be installed. this can be found here

When the installations are done, the PC will recognize the shield.

To verify this go to, device management and look for the following 3 ports.

Now open the Qnavigator software and follow the instructions shown in the program.

2.7.2 Programming the shield via Arduino //to do testen met Arduino

Before connecting anything first check if the headers are in the correct position. The Vin header should be on PWR if a

power adapter is being used. When this is the case, remove the USB PWR header. If no power adapter is used, set Vin

on 5V and connect the USB PWR header.

Now connect the USB cable to the device and to the PC. The green LED will light up. Now press the Power switch for 3

seconds. The Stat LED should light up and the Net light should start blinking.

//

Once this is done, download the Arduino IDE software on your PC. This can be found here:

https://www.arduino.cc/en/Main/Software. To communicate with the shield a standard Arduino library called

“SoftwareSerial” is needed. This is already installed with the Arduino IDE.

Information can be found here: https://www.arduino.cc/en/Reference/SoftwareSerial

Once Arduino IDE has finished installing open the software.

2.8 GPIO The ERF3000 shield has multiple GPIO pins. The GPIO header* has all the GPIO pins from the BG96 module. The

Arduino headers 1 and 2* have the normal Arduino GPIO pins, if the module is used in combination with a Arduino.

This allows for the possibility to add extra functionality to the shield, and integration in your application.

*the GPIO and Arduino header pinout can be found in chapter 3 Pin Assignment
