This Keyestudio KS0216 Raspberry Pi GPS Plate (shield) features high performance and low power consumption. It utilizes the NEO-6M Module developed by U-blox. The GPS Module is connected through the 2*20 expansion pins of Raspberry Pi. It features a large size ceramic antenna, sending locating information to GPS through the serial port. It can track up to 8 satellites on 50 channels at high speed, and it produces very accurate location data.

Plug the GPS Plate into Raspberry Pi 3. Upload your code to Raspberry Pi 3, and you can find your exact location within a few meters. It also provides you with very accurate time! It can be used in car navigation, personal positioning, fleet management, navigation and so on.

BerryGPS-IMU v2 Plate has been designed to fit perfectly with the Raspberry Pi Zero. It is also compatible with all other versions Raspberry Pi, including the Pi 3B+.
BerryGPS-IMU v2 uses the M20048 from Antenova, which is a high quality GPS module which is able to track 22 satellites. The BerryGPS-IMU v2 is a GPS module which also includes the sensors that can be found on the BerryIMU v2 Plate.

BerryGPS-IMU v2 is also fitted with a barometric sensor (BMP280) which can be used to calculate altitude. A temperature sensor is also included.

Sensors included are;

  • GPS
  • Accelerometer
  • Gyroscope
  • Magnetometer (Compass)
  • Barometric/Altitude
  • Temperature

IMU:

An inertial measurement unit, or IMU, measures and reports on velocity, orientation and gravitational forces, using a combination of an accelerometer, gyroscope and a magnetometer.

Raspberry (Banana) Pi to PC using a Serial Connection

USB-to-serial Console Cable

Using a Connection via a Serial Port is a low-level way to send data between the Raspberry (Banana) Pi and another computer system. There are two main ways in which it can be used:
  • Connecting to a PC to allow access to the Linux console. This can help to fix problems during boot, or to log in to the Pi if the video and network are not available.
  • serial interface. This can be useful if you want the Pi to control another device.
