1Introduction
This document defines and specifies the application of L89 EVB (Evaluation Board) which is a type of
assistant tool used by engineers to develop and test Quectel L89 modules.
1.1. Safety Information
The following safety precautions must be observed during all phases of operation, such as usage, service
or repair of any cellular terminal or mobile incorporating L89 module. Manufacturers of the cellular
terminal should send the following safety information to users and operating personnel, and incorporate
these guidelines into all manuals supplied with the product. If not so, Quectel assumes no liability for
customers' failure to comply with these precautions.
Ensure the use of the product conforms to the local safety and environment
regulations, and is allowed in the country and the environment required.
Keep away from explosive and flammable materials. The use of electronic
products in extreme power supply conditions and locations with potentially
explosive atmospheres may cause fire and explosion accidents.
The product must be powered by a stable voltage source, and the wiring shall
conform to security precautions and fire prevention regulations.
Proper ESD handling procedures must be followed throughout the mounting,
handling and operation of any application that incorporates the module to avoid
ESD damages.

4EVB Operation Procedures
L89 module is upgraded through the UART port (UART_TX/UART_RX) in two methods: firmware
downloading in normal working mode and firmware downloading in boot download mode.
4.1. Communication through Micro-USB Interface
Step 1: Connect the EVB to the PC by using a Micro-USB cable through Micro-USB interface, and then
switch POWER pin to ON state to power on the EVB.
Step 2: Run the USB flash drive on the PC to install the USB driver, where the USB port numbers can be
viewed through the PC Device Manager, as shown below.
Figure 9: USB Ports
Step 3: Install and then use the QCOM tool provided by Quectel to implement the communication
between L89 module and the PC.

The following figure shows the COM Port Setting interface of the QCOM tool. The customers can select
the correct “COM Port” (USB Port shown in the foregoing figure) and set the correct “Baudrate” (the
default value: 9600bps). For more details of usage of the QCOM tool, please refer to
Quectel_QCOM_User_Guide.

4.2. Firmware Downloading
L89 module supports the firmware downloading in both normal working mode and boot download mode
by using the tools of STA808x/9x Firmware Upgrade and TeseoIII XLoader respectively.
4.2.1. Firmware Downloading in Normal Working Mode
Steps of firmware downloading in normal working mode are as follows:
Step 1: Connect the EVB to a PC by using the USB cable.
Step 2: Switch the POWER pin to ON state to power on the EVB.
Step 3: Run the STA808x/9x Firmware Upgrade Tool and configure the tool as shown below.
Figure 11: STA808x/9x Firmware Upgrade Tool Configurations for Firmware Upgrade
Step 4: Click button and then reset the module to upgrade the firmware.

4.2.2. Firmware Downloading in Boot Download Mode
Steps of firmware downloading in boot download mode are as follows:
Step 1: Connect the EVB to a PC by using the USB cable.
Step 2: Long press DL button (the 3D-FIX/BOOT pin of L89 will be pulled up to connect the VCC pin by
using a 10kΩ resistor), and switch POWER pin to ON state to power on the EVB. Once the high
voltage level of 3D-FIX/BOOT pin has been detected during power-up, the module will enter
bootloader download mode.
Step 3: Release DL button to enable 3D-FIX/BOOT pin of L89 to return to normal floating.
Step 4: Run the TeseoIII XLoader tool and configure the tool as shown below.
