GPS 6 Click Board™

Product Code: MIKROE-5115

How Does The GPS 6 Click Board™ Work? The GPS 6 Click Board™ as its foundation uses the A2200-A, a high-performance Global Positioning System (GPS) module from Lantronix. This GPS module enables fast acquisition and tracking built on the SiRFstar IV technology. It operates with a frequency of 1,575GHz with accuracy from 2 to 2.5m and fully addresses the demand for the lowest power consumption. It is characterized by high sensitivity of -148dBm during acquisition or while tracking (navigation sensitivity of -160dBm and tracking sensitivity of -163dBm) besides removing jammers during acquisition, allowing usage in many different environments and under harsh operating conditions. The GPS 6 Click Board™ is configured in the Self-Start mode of operation by ON_OFF and WAKEUP pins connected together. The entire power operation will be activated in Self-Start mode once the 3V3 power rail is applied. The A2200-A communicates with MCU using the UART interface with commonly used UART RX and TX pins as its communication protocol 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 A2200-A. On this line, the MAX809 is also connected, which performs a single function; it asserts a reset signal whenever the 3V3 supply voltage declines below a preset threshold. In addition to precise positioning, GPS also allows for accurate timing due to the synchronized atomic clocks in the GPS satellites. While the current date and time are transmitted in NMEA sentences (UTC), a precise and accurate timing signal is provided via the 1PPS pin of the A2200 GPS receiver and indicated via a red LED indicator marked as PPS. The GPS 6 Click Board™ possesses the SMA antenna connector with an impedance of 50Ω, which can be used to connect the appropriate passive antenna that MikroE has in its offer for improved range and received signal strength. The GPS 6 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.
