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.
Connection and sample program
The chip has 5 goldpin pins - raster 2,54 mm. Their functions are described in the table below.
| Pin | Description |
|---|---|
| VCC | Supply voltage 3.3 V or 5 V. |
