Introduction

Septentrio’s mosaic modules are low-power multi-band multi-constellation GNSS receiver packaged in a 31x31mm LGA module. The module operates from a single 3V3 power supply (VDD_3V3). The ANT_1 input pad receives the RF signal from the main antenna. On dual-antenna modules (mosaic-H), a second antenna input is available (ANT_2) for the auxiliary antenna. A 3V to 5.5V DC voltage can be applied to the main antenna from the VANT pin, obviating the need for an external antenna supply. The internal bias control circuit detects overcurrent conditions (>150mA) and protects the module in case of short circuit. The module can use its internal TCXO as frequency reference, but also accepts an external frequency reference on the REF_I pin (mosaic-T only). Two event timer pins and a PPS output are available (1.8V LVTTL). The module features a rich set of communication interfaces:

• Four serial ports (3.3V LVTTL), three of them with hardware flow control.
• USB.
• Ethernet (the PHY is external to the module).
• SDCard interface for logging to an external SD card.
• GPIO and LEDs output.
