Description

Quectel L80 module is the heart of this Raspberry Pi GPS add-on. Combining advanced AGPS called EASY™ (EmbeddedAssist System) and proven AlwaysLocate™ technology, L80 achieves the highest performance and fully meets the industrial standard.

EASY™ technology ensures this GPS shield for Raspberry Pi can calculate and predict orbits automatically using the ephemeris data (up to 3 days) stored in internal RAM memory, so L80 GPS Module can fix position quickly even at indoor signal levels with low power consumption. With AlwaysLocate™ technology, L80 can adaptively adjust the on/off time to achieve balance between positioning accuracy and power consumption according to the environmental and motion conditions.

With its compact design, high precision and sensitivity, this GPS shield is perfectly suitable for a broad range of M2M applications such as portable device, automotive, tracking, security and industrial PDA, especially suitable for special applications, like GPS mouse and OBD.

Both UART and USB communication with the L80 GPS module is available. The shield can be used easily via NMEA GPS Commands.

Features

  1. Fully compatible with Raspberry Pi models that have the 40-pin GPIO header (3, 2, B+, A+, Zero)
  2. Can be used standalone with PC/Laptop and other electronics over micro USB, without stacking with Raspberry Pi thanks to USB-UART translator chip on the shield.
  3. EASY™, advanced AGPS technology without the need of external memory
  4. Embedded patch antenna: 15.0 x 15.0 x 4.0mm
  5. Built-in LNA for better sensitivity
  6. Extremely low power consumption, [email protected] mode
  7. FLP mode, about 50% power consumption of normal mode
  8. High sensitivity, -165dBm @Tracking, -148dBm @Acquisition
  9. 66 acquisition channels, 22 tracking channels
  10. Balloon mode, for high altitude up to 80km
  11. Support QZSS, DGPS, SBAS (WAAS/EGNOS/MSAS/GAGAN)
  12. Anti-Jamming, Multi-tone Active Interference Canceller
  13. PPS VS. NMEA can be used for time service
  14. Working temperature range: -30°C to +80°C

 

Key Applications

  1. Vehicle Management
  2. Security and asset tracking
  3. Connected PND
  4. GIS Application
  5. Bike sharing
  6. Smart parking

 

Technical Details

Connection Types

USB: If you don’t want to occupy UART port on the Raspberry Pi, you should slide the available communication switch on the shield to USB and plug the shield via micro USB to Raspberry Pi. You can start to send and receive commands over USB thanks to ‘USB to serial UART translator chip’ on the shield.

UART: The UART pins will be available to use, with 3.3V power domain, directly connected the UART port of Raspberry Pi. Be sure the communication switch on the shield already switched to Pi side.

Note: Both USB and UART communication baud rate is 9600bps.

Warning

  • To get quickly and more accurate positioning from GPS satellites, you should be outdoor and GPS module is facing to the sky.
  • When the full communication with the satellites is achieved(3D Fix), the Signal led starts to pulse(1pps) and the exact data comes at that time.
  • For the best working condition, use at least a 2A adapter or power source.
