2. Product Overview

The SC872-A Evaluation Kit packages the SC872-A Module in a plastic case containing

the necessary interface components and a cable with a USB connector.

The SC872-A module contains a GNSS receiver with integrated antenna based on the

MediaTek MT3333 chipset. It also includes a high performance LNA, TCXO, SAW

filter, RTC, Backup battery, and LDO.

The receiver can simultaneously search and track satellite signals from the entire

spectrum of GNSS constellations available: GPS, Glonass, Galileo, BeiDou, QZSS and

SBAS. However, the antenna is designed for GPS and GLONASS bands, therefore a

wider bandwidth antenna should be used to verify BeiDou performance.

Communication is performed over a UART serial port using the NMEA-0183 protocol.

The SC872-A features high sensitivity, low power consumption and fast Time To First

Fix (TTFF). It also supports jamming immunity.

The EVK supplies power from the USB interface to the module.

5.1. Installing the USB Drivers

1. Before connecting the evaluation kit, ensure that the FTDI USB drivers are installed.

If needed, install the drivers from the USB flash drive by double-clicking the USB

driver executable and following the onscreen directions.

2. Verify that the proper jumpers have been installed.

3. Connect the provided Active Antenna to the SMA connector.

4. Connect the evaluation kit to the PC. It will automatically be detected and the USB

driver will be installed. If the system does not automatically find the driver, the user

may provide the path to the USB drive.

5. Select "Continue Anyway" to proceed

Figure 5-1 USB Installation message

6. After the device driver has been installed, the user should check the “Device

Manager” in Windows for the evaluation board COM port number to be present. This

port number is required by TelitView or other software to communicate with the

EVK.

7. Turn power on to EVK.

NOTE:

After installation of the USB FTDI driver, Windows may install a “Microsoft Serial

BallPoint mouse” if the EVK is powered on when connecting the USB cable.

If this happens, it will show up on the “Device Manager” under “Mice and other

pointing devices”. If this is displayed, power the EVK off, disconnect it from the USB

port, and uninstall the “Microsoft Serial Ball Point mouse”. Then, reconnect the EVK

while powered off, and verify that it is now displayed as a USB serial com port under

“Ports (COM & LPT)”.
