Walksnail WS-M181 GPS

 Bullet Point

• With small size, light weight, fast positioning, and stable connection. It is suitable for FPV, RC airplane, quadcopter and others to enhance the flight experience.

• Featuring the u-blox M10 platform UBX-M10050 GNSS chipset and BUILT-IN QMC5883 MAG, the module offers stronger performance and more accurate positioning.

• The ultra-thin ceramic antenna uses a special spray painting process to prevent oxidation and scratching, ensuring consistent positioning performance.

• The built-in battery can realize hot start and realize positioning quickly.

• It offers six positioning modes, providing more flexible combinations (default GPS + GLONASS + BDS multi-mode positioning).The measured maximum number of search sats can cover 32pcs.

Note:
Because the GPS chip is a new 10th generation chip, the flight controller needs to flash firmware Betaflight  4.3.0 and above, and the firmware below 4.29 uses the NMEA protocol.
