Product description: Velleman VMA430 - GPS / GLONASS u-Blox NEO-7M UART module with antenna

GPS / GLONASS NEO-7M-C module on board with goldpin connectors. It supports 50 channels, operates from 3.3 V to 5 V, communicates via UART interface (TX, RX), and refresh rate is up to 5 Hz. The module is equipped with straight goldpins.

The chip has soldered straight goldpin connectors and a ceramic antenna.

Main features of Velleman VMA430

  • GLONASS system - Russian satellite navigation system covering the whole globe.
  • Simple communication - device communicates through simple UART interface, i.e. RX and TX pins with default speed 9600 bps. Thanks to wide voltage range, it can work with both 3.3 V devices, like STM32 and Raspberry Pi, and 5 V devices, like Arduino
  • Built-in ceramic antenna - gives sensitivity of -162 dB. Additionally, the module is equipped with SMA connector for connecting external antenna.
  • Backup battery - on the back side there is a battery that allows you to keep data in the device during a power outage.

The manufacturer provides user's guide with description of module operation.
