La carte GPS 5 Click Board™ est une carte complémentaire compacte qui fournit aux utilisateurs des services de positionnement, de navigation et de chronométrage. Cette carte comprend le M20050-1, un récepteur de module GPS compact utilisant la puce flash MediaTek MT3333, fournissant un récepteur GNSS complet pour des performances optimales d'Antenova. Le récepteur suit 3 constellations GNSS simultanément (GPS+Galileo+GLONASS ou GPS+Beidou) pour améliorer la localisation et le TTFF (Time-to-first-fix) et dispose de modes basse consommation configurables fonctionnant à partir d'une alimentation de 3,3 V. En plus de la possibilité d'utiliser une antenne externe, une alimentation de secours et divers indicateurs visuels, le M20050-1 dispose également d'un TXCO précis de 0,5 ppm garantissant un TTFF court ainsi que des algorithmes multi-trajets, ce qui améliore la précision de la position dans les environnements urbains. Cette carte Click™ convient à un large éventail d'applications GPS où les performances, le coût et le délai de mise sur le marché sont des considérations primordiales.
La carte Click Board™ GPS 5 est supportée par une bibliothèque compatible mikroSDK, qui comprend des fonctions qui simplifient le développement logiciel. Cette carte Click Board™ est un produit entièrement testé, prêt à être utilisé sur un système équipé du socket mikroBUS™.
How Does The GPS 5 Click Board™Work?
The GPS 5 Click Board™ is based on 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 labelled 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.
The GPS 5 Click Board™ 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 Board™ 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.
The GPS 5 Click Board™ can only operate with a 3.3V logic voltage. 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.
