Ready to sky BN-880 GPS Module
The Ready to sky BN-880 is a high-precision GPS module designed for embedded systems, IoT applications, and navigation projects requiring accurate real-time positioning data. Professional engineers, roboticists, and IoT developers rely on this module for drone navigation, autonomous vehicle systems, asset tracking, and geolocation-based applications. It solves the critical challenge of obtaining reliable GPS coordinates with minimal power consumption and compact form factor, making it ideal for battery-powered and space-constrained embedded projects.
Product Overview
The BN-880 GPS module operates on the global positioning system using a 50-channel receiver architecture that simultaneously tracks multiple satellites for rapid position acquisition and exceptional accuracy. This module integrates a high-sensitivity antenna with advanced signal processing capabilities, delivering position fixes within 2.5 meters under optimal conditions. The module communicates via UART serial interface at configurable baud rates, making it compatible with Arduino, Raspberry Pi, STM32, and other microcontroller platforms without requiring additional signal conditioning circuits.
What distinguishes the BN-880 from competing modules is its superior cold start time of approximately 32 seconds and warm start capability of just 1 second, combined with its ultra-low power consumption of 45mA during active tracking. The module features built-in EEPROM for storing configuration parameters, supports multiple NMEA sentence outputs for comprehensive navigation data, and includes a real-time clock for timestamp accuracy. Its industrial-grade design ensures reliable operation across temperature ranges from -10°C to 60°C, making it suitable for both indoor laboratory testing and outdoor field applications.

How to Use
To integrate the Ready to sky BN-880 GPS module with your microcontroller project, establish UART serial communication by connecting the module's RX pin to your microcontroller's TX pin and TX pin to the microcontroller's RX pin, with GND connections common to both devices. Supply 3.3V to 5V DC power to the VCC pin (the module automatically regulates internal voltage), and ensure the antenna has clear line-of-sight to the sky for optimal signal reception. Configure your microcontroller's UART peripheral to operate at 9600 baud rate (default setting), then parse incoming NMEA sentences to extract latitude, longitude, altitude, and timestamp data from the GGA and RMC sentence formats.
For Arduino implementations, use the SoftwareSerial library to create a serial connection on any digital pins, then parse NMEA data character-by-character using simple string manipulation or dedicated libraries like TinyGPS++. Allow 30-60 seconds for initial cold start acquisition when the module powers on, during which it downloads satellite almanac data; subsequent warm starts will achieve position fixes within 1-5 seconds. For power-sensitive applications, implement sleep modes by toggling the module's enable pin or reducing UART polling frequency during non-critical periods. Always validate GPS data quality by checking HDOP (horizontal dilution of precision) values below 2.0 and ensuring at least 4 satellites are locked before trusting position estimates for critical navigation decisions.
Frequently Asked Questions
What is the difference between cold start and warm start in GPS modules?
Cold start occurs when the GPS module powers on without any prior satellite or ephemeris data, requiring it to download complete satellite orbital information from the GPS constellation, typically taking 30-45 seconds. Warm start happens when the module retains ephemeris data in its internal memory from a previous session, allowing it to reacquire satellites in 1-5 seconds. The BN-880 achieves warm start times of approximately 1 second, making it ideal for applications requiring frequent position updates without excessive startup delays.
Can the BN-880 module work indoors or through windows?
GPS modules require direct line-of-sight to satellites and cannot penetrate solid walls effectively. However, the BN-880's high-sensitivity 50-channel receiver may occasionally acquire weak signals through windows or thin building materials, though accuracy degrades significantly and acquisition times extend considerably. For reliable indoor positioning, consider alternative technologies like WiFi triangulation, Bluetooth beacons, or ultra-wideband (UWB) systems designed specifically for indoor environments.
How do I configure the BN-880 baud rate and NMEA output sentences?
The BN-880 comes pre-configured at 9600 baud with standard NMEA output sentences enabled. To modify settings, you must send specific configuration commands via UART using the proprietary command protocol documented in the module's datasheet. Most users find the default configuration suitable for standard applications; however, advanced users can increase baud rates to 115200 for faster data streaming in high-frequency logging applications. Configuration changes are stored in the module's EEPROM and persist across power cycles.
