GNSS ZOE Click Board™

The GNSS ZOE Click Board™ features high precision GNSS, dual-frequency RF front-end, onboard serial flash memory, message integrity protection, anti-jamming, anti-spoofing, and many more, makes this Click board™ meet even the most stringent requirements in versatile industrial and consumer applications, such as UAVs, vehicles and assets tracking. For RF optimization, the ZOE-M8Q module features the integrated front-end SAW filter and an additional front-end LNA for increased jamming immunity and easier antenna integration. The GNSS ZOE Click Board™ is designed mainly for using with GNSS/GLONASS compatible active antennas.

How Does The GNSS ZOE Click Board™ Work?

The GNSS ZOE Click Board™ features the ZOE-M8Q are u-blox's super small, highly integrated GNSS SiP (System in The package) modules based on the high performing u-blox M8 concurrent positioning engine. The ultra-miniature form factor integrates a complete GNSS receiver including SAW filter, LNA and TCXO. Incorporating ZOE-M8 into customer designs is simple and straightforward, thanks to the fully integrated design, single voltage supply, low power consumption, simple interface and sophisticated interference suppression that ensure maximum performance even in GNSS-hostile environments.

The ZOE-M8 GNSS SiPs are concurrent GNSS receivers which can receive and track multiple GNSS systems: GPS, Galileo, GLONASS and BeiDou. Owing to the dual-frequency RF front-end architecture, either GLONASS or BeiDou can be processed concurrently with GPS and Galileo signals, thereby providing reception of three GNSS systems. By default, the M8 receivers are configured for concurrent GPS and GLONASS, including SBAS and QZSS reception. If power consumption is a key factor, then the receiver should be configured for a single GNSS operation using GPS, Galileo, GLONASS or BeiDou and disabling QZSS and SBAS.

Thanks to onboard 64 Mbit SQI flash memory, GNSS ZOE click can also be used in data logging applications. The data logging feature enables continuous storage of position, velocity and time information to the flash memory. The information can be downloaded from the receiver later for further analysis or for conversion to a mapping tool. Besides the data logging feature, the flash memory can also be used for the AssistNow Offline service, which allows the users to download long-term orbit data over the Internet at their convenience and store it to the onboard 64 Mbit SQI flash memory.

The ZOE-M8 SiP supports both SPI and I2C/UART communication protocol configurations. Therefore, this Click board™ have communication interface selection jumpers, named COMM SEL, in order to allow the user to set whether to use SPI communication or I2C/UART combination. Note that there is five SMD jumpers and all of them should be in the same position.

The GNSS ZOE Click Board™ can operate with 3.3V MCUs only, it is set to work over the I2C by default, and it is already equipped with the pull-up resistors. It is ready to be used as soon as it is inserted into a mikroBUS™ socket of the development system.
