U-BLOX NEO-6M module (GY-GPS6MV2)

SPECIFICATIONS:

• Input Supply Voltage Range: 3.3V-6V, on board voltage regulator maintains 3.3V
• I/O Maximum Logic Level: 3.6V
  • We have tested it with direct connection to the 5V serial pins on an Arduino and found it to work fine but extended periods of time may be different
  • To use with a 5V logic device, such as an Arduino, we suggest level shifting the 5V TX signal using one of the following:
    • Two 1N4148 diodes in series between the TX pin on your 5V device and the RX pin on this GPS module (will drop voltage to ~3.6V)
      • Only recommended for baud rates of 9600 and less
    • Use a logic level converter module 
• WAAS (Wide Area Augmentation System) enabled GPS unit
• <1 second to first fix (TTFF) for hot starts
• 27 seconds to first fix (TTFF) for cold starts
• On board LED will blink after module acquires a position fix and will continue blinking as long as the module has a fix
• 50 Channel NEMA GPS receiver
• UART: 9600 baud by default, but is configurable from 4800 to 115200 baud
• 5Hz max update rate
• External EEPROM for configuration storage
• Four plated mounting holes, 3mm in diameter
• One additional non-plated mounting/antenna cable hole, 4mm in diameter
• Position Accuracy: 2 m and better with multiple good satellite signals
• Velocity Accuracy: 0.1 m/s
• Maximum Velocity: 500 m/s
• Heading Accuracy: 0.5 degrees while moving
• On board battery for battery backed RAM (BBR)
  • Battery is recharged through a simple diode and resistor charger circuit from the on board voltage regulator’s 3.3V output
• Three different power modes 
  • Two continuous operating modes:
    • Maximum Performance Mode – continuously uses the acquisition engine, resulting in the best possible time to first fix (TTFF)
    • Eco Mode – optimizes the use of the acquisition engine to minimize current consumption
  • One intermittent operating mode
    • Power Save Mode – draws only 11mA – Utilizes cyclic tracking, with configurable update periods, which reduces the average power consumption significantly
• -156dBm Hotstart sensitivity
• Weight: 17.6g (0.6oz)
• Dimensions of GPS Module: 36mm (1.42in) x 25.8mm (1.02in) x 4mm (0.16in)
• Dimensions of Antenna: 25.5mm (1in) x 25.5mm (1in) x 8.8mm (0.35in)
