NEO-M8L GPS Module with UART and SPI Interface

Breakout GPS module built on the u-blox NEO-M8L receiver, with UART and SPI outputs for flight controllers, GPS trackers and Arduino, Raspberry Pi or ESP32 projects. It runs from a 3.3–5 V supply and supports 2D and 3D fixes with cold, warm and hot start.

Key features

• Multi-constellation reception: GPS, GLONASS, Galileo and BeiDou
• L1-band receiver (1575.42 MHz) with accuracy down to about 2.5 m in open sky
• UART and SPI interfaces for flight controllers and microcontrollers
• Low draw of around 22 mA in normal operation
• Rated from -40 °C to +85 °C for outdoor and vehicle installs

The NEO-M8L is the dead-reckoning member of the u-blox M8 family, aimed at vehicle tracking; on a drone it works as a standard UART GPS. No compass is listed, so add a separate magnetometer if your flight controller needs heading for position hold or return-to-home.
