GPS 5 Click is a compact add-on board that provides users with positioning, navigation, and timing services. This board features the M20050-1, a compact GPS module receiver using the MediaTek MT3333 flash chip, providing a complete GNSS receiver for optimum performance from Antenova. The receiver tracks 3 GNSS constellations concurrently (GPS+Galileo+GLONASS or GPS+Beidou) to considerably enhance location and TTFF (Time-to-first-fix) and has configurable low power modes operating from a 3.3V power supply. In addition to the possibility of using an external antenna, backup power, and various visual indicators, the M20050-1 also has an accurate 0.5ppm TXCO ensuring short TTFF alongside multi-path algorithms, which improves position accuracy in inner-city environments. This Click board™ is suitable for a broad spectrum of GPS applications where performance, cost, and time to market are prime considerations.

GPS 5 Click as its foundation uses the M20050-1, an integrated GNSS receiver module with an integrated antenna incorporating the MediaTek MT3333 flash chip from Antenova. The M20050-1 tracks 3 GNSS constellations concurrently (GPS+Galileo+GLONASS or GPS+Beidou) to considerably enhance the location and has configurable low power modes alongside acquisition and tracking sensitivity of -163dBm and -165dBm. This module offers indoor and outdoor multi-path detection and compensation and has an accurate 0.5ppm TXCO that ensures short TTFF besides an active interference cancellation (AIC) feature. This Click board is ideal for asset tracking/ personal safety, navigation devices, and sports equipment applications based on good attributes.

The M20050-1 has three power-saving modes: Standby, Backup, and Periodic. Standby mode is a power-saving mode initiated either with a hardware signal labeled as STB and routed on the PWM pin of the mikroBUS™ socket or by a software command. It shuts down the RF section of the module, putting the processor into Standby mode. The RTC is kept alive, and the RAM power is maintained to keep the module configuration. Periodic mode is a user-configurable mode that reduces current consumption by only waking the module for short periods to maintain FIX data.

Backup mode is accessed due to the absence of the main board power supply VCC. For this reason, there is an additional backup power supply in the form of a battery that powers the RAM and RTC sections of the receiver and needs to be applied at all times for Backup mode to run correctly. Once initiated, the RTC and all configurations are saved along with any ephemeris data to allow quick TTFF once the VCC is re-applied.

GPS 5 Click communicates with MCU using the UART interface with commonly used UART RX and TX pins operating at 115200bps by default configuration to transmit and exchange data with the host MCU. It also possesses an active-low reset signal routed on the RST pin of the mikroBUS™ socket that activates a hardware reset of the M20050-1. The reset function can also be used using an onboard RESET button.

In addition to precise positioning, the GPS 5 Click also has an accurate timing signal indicated via a red LED indicator marked as 1PPS, a blue LED indicator marked with FIX, which shows once a GPS fix has been obtained, as well as the possibility of using an external active antenna which can also be found in our offer, activated through EN pin of the mikroBUS™ socket.

This Click board™ can be operated only with a 3.3V logic voltage level. The board must perform appropriate logic voltage level conversion before using MCUs with different logic levels. However, the Click board™ comes equipped with a library containing functions and an example code that can be used, as a reference, for further development.
