GPS + BDS Dual-Mode GNSS Module for Arduino Flight Controller

🛰️ GPS + BDS Dual-Mode Satellite Positioning Module

A compact GNSS receiver module that tracks GPS and BeiDou (BDS) satellites at the same time, so it can fix position faster and hold it in places where a single-constellation receiver struggles. Serial NMEA output means it works with virtually any microcontroller.

✨ Key Features

• Dual-constellation reception: GPS plus BeiDou for faster, more stable fixes
• Standard UART serial output with NMEA 0183 sentences – parse it with any MCU
• Battery-backed configuration keeps settings between power cycles
• Active antenna connector for the supplied patch antenna
• Small footprint that fits flight controllers, trackers and handheld builds
• 3.3V-5V friendly logic for Arduino, ESP32, STM32 and Raspberry Pi

🔬 Specifications

• Constellations: GPS (L1) + BDS (B1)
• Channels: multi-channel parallel tracking
• Position accuracy: approx. 2.5m CEP (open sky)
• Update rate: 1Hz default, configurable up to 10Hz
• Output: NMEA-0183 over UART (TX/RX), default 9600bps
• Supply: 3.3V-5V DC
• Antenna: active ceramic patch via u.FL/SMA lead

💡 Perfect For

Flight controllers and FPV telemetry, vehicle and asset trackers, GPS-disciplined clocks, geotagging loggers, and robotics that need a reliable position fix.
