Description Attachments

The SparkFun Triband GNSS RTK Breakout features the UM980 GNSS high precision RTK position module from Unicore Communications. The UM980 is a 1408-channel GNSS receiver based on the Nebulas IV™ that can simultaneously track GPS L1/L2/L5, GLONASS L1/L2, Galileo E1/E5a/E5b/E6, Beidou B1I/B2I/B3I/B1C/B2a/B2b, QZSS L1/L2/L5, and SBAS. This board allows you to pinpoint the X, Y, and Z location of any object within roughly the width of your fingernail. With an RTK solution, the module achieves a horizontal accuracy of about 8mm and vertical accuracy of 15mm. The UM980 supports both rover and base station operations.

Equipped with a rechargeable backup battery, the module retains the latest configuration and satellite data, enabling a 'warm-start' that significantly reduces the time-to-first-fix. The module's survey-in mode allows it to function as a base station, producing RTCM 3.x correction data. A secure SMA connector is provided for attaching a Triband GNSS antenna.

The UM980 module currently supports serial UART only. All three serial UART ports are accessible via a USB-C connector through CH340, a 4-pin locking JST connector, and a BlueSMiRF header. Unique pins are also available on the board's edge, with various jumpers included for configuring power and LEDs.
