Soldered L86-M33 - GPS/GLONASS/Galileo GNSS breakout

Description

The device GNSS GPS L86-M33 Breakout by Soldered is a GNSS receiver module for determining position using the GPS, GLONASS and Galileo satellite systems. The L86-M33 receiver provides positioning accuracy of approximately ±2.5m under optimal conditions, while the maximum data update rate is 10Hz. The module can determine information including geographic coordinates, altitude, speed and direction of movement.

The L86-M33 uses EASY technology for satellite orbit prediction, AlwaysLocate for reducing power consumption and the integrated LOCUS logger for storing positioning data. Tracking sensitivity reaches -167dBm, helping maintain reception even when the view of the sky is partially obstructed. Positioning data is transmitted as standard NMEA messages through the UART interface.

The board features an integrated ceramic antenna as well as an IPX connector for an external GNSS antenna. The PPS output provides a timing pulse synchronized with the GNSS system, while the additional RST and F-ON pins allow control of the receiver. The CR1220 battery holder can retain timing and GNSS data after the main power supply is disconnected, which may reduce the time required to obtain a new position fix after power-up. The CR1220 battery is not included.

The board can be powered from 5V through the onboard regulator or directly from 3.3V after configuring the appropriate jumpers. Current consumption is approximately 26mA during satellite tracking and approximately 30mA during acquisition, while the AlwaysLocate function can reduce consumption to approximately 3.5mA. The board measures 54 × 38mm and features mounting holes suitable for M3 screws.
