GPS Module - GP1818MK (56 Channel)

The GP-1818MK is a low-cost - high performance GPS module with built in antenna. It can provide position, velocity, and accurate timing through the standard NMEA-0183 protocol. Being low power and compact in design, the GP-1818MK is perfect for basic tracking and positioning, especially with respect to battery powered systems.

This is the recommended replacement for those using the 20U7 Module. There should be minimal changes needed to move from that module to the GP-1818MK. The module comes terminated with a 3-pin connector similar to that on the 20U7 Module. It features the same 56-channel, low power capabilities as well.

  • Build on high performance GPS single chip MT3337
  • High Sensitivity -165 dBm
  • Low power consumption: Max 55mA @ 3.3V
  • Integrated LNA with low-gain mode for active antenna option
  • 66 channels in Search mode and 33 channels "All-in-View" tracking
  • Up to 60,000 simultaneous search windows for fast TTFF and high sensitivity acquisitions
  • Average cold start time under 29seconds (open sky)
  • Support standard NMEA-0183 protocol
  • Patch Antenna Size: 18mm W X 18mm D X 7mm H
  • RoHS compliant (Lead-free)

GPS Module - GP1818MK (56 Channel) Product Help and Resources

Core Skill: Programming

If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.

3 Programming

Skill Level: Competent - The toolchain for programming is a bit more complex and will examples may not be explicitly provided for you. You will be required to have a fundamental knowledge of programming and be required to provide your own code. You may need to modify existing libraries or code to work with your specific hardware. Sensor and hardware interfaces will be SPI or I2C.

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

3 Electrical Prototyping

Skill Level: Competent - You will be required to reference a datasheet or schematic to know how to use a component. Your knowledge of a datasheet will only require basic features like power requirements, pinouts, or communications type. Also, you may need a power supply that?s greater than 12V or more than 1A worth of current.

    Bought this on Mouser with a bunch of other components. Wish the manual had been more clear about this, but even though it accepts 3.3 - 5V power, the data line is 3.3V only. In other words, even when powered by 5V, the serial data is 3.3V so you'll need a level shifter or something if planning to use with 5V circuitry. Wish I'd known that but nothing in the manual indicates the data voltage, so I had naively assumed it used the same as the power voltage.
