MIKROE-1887

2. Soldering the headers Before using your click board, make sure to solder 1x8 male headers to both left and right side of the board. Two 1x8 male headers are included with the board in the package. 1 4. Essential features GNSS click 2 3 The L76 module on GNSS2 click integrates performance-enhancing Quectel technologies. It can automatically predict satellite orbits from data stored in its internal flash (EASY technology) and it can adaptively adjust its on/off time to balance between positioning accuracy and power consumption (AlwaysLocate technology). GNSS2 click Turn the board upside down so that Turn the board upward again. Make sure also features a VBAT connector for connecting the bottom side is facing you upwards. to align the headers so that they are an external power supply which can supply Place shorter pins of the header into the perpendicular to the board, then solder the power to the modules SRAM memory (storing appropriate soldering pads. pins carefully. GPS information necessary for quick start-up). 1. Introduction GNSS2 click carries Quectels L76 module 3. Plugging the board in and an SMA antenna connector. L76 can click acquire both GPS and GLONASS signals. The Once you have soldered the headers your larger number of visible satellites increases board is ready to be placed into the desired BOARD positioning accuracy (<2.5m CEP) and mikroBUS socket. Make sure to align the www.mikroe.com decreases acquisition time (<5s TTFF with cut in the lower-right part of the board with warm start). GNSS2 click communicates the markings on the silkscreen at the with the target board MCU through UART mikroBUS socket. If all the GNSS2 click manual ver 1.00 (RX, TX) pins as well as Force on (AN), RST pins are aligned correctly, (RST), Standby (PWM). The board can use push the board all the way either 3.3 or 5V power supply and logic levels. into the socket. 01000000783418. Code examples 5.
