SparkFun has additional expanded its burgeoning line of high-accuracy positioning merchandise with the launch of the SparkFun GNSS-RTK Useless Reckoning Breakout — placing a u-blox ZED-F9K on the tip of a Qwiic connector for solder-free prototyping.
“The SparkFun ZED-F9K GNSS Breakout is a excessive precision, sensor fusion geospatial board with equally spectacular configuration choices and takes benefit of u-blox’s Automotive Useless Reckoning (ADR) expertise,” the corporate writes of its newest launch. “The ZED-F9K module gives a extremely correct and steady place by fusing a 3D IMU sensor, wheel ticks, a car dynamics mannequin, correction knowledge, and GNSS measurements.”

A part of a rising vary of high-accuracy location and positioning merchandise, the brand new board is constructed across the u-blox ZED_F9K – a 184-channel world navigation satellite tv for pc system (GNSS) receiver with GPS, GLONASS, Galileo, and BeiDou help plus an built-in accelerometer and gyroscope. On prime of its, it presents Actual Time Kinematic (RTK) correction — that means that, when paired with a appropriate base station for correction knowledge, the positioning accuracy sits at round 20cm (slightly below 8″).
Different options of the board embrace help for low-signal circumstances, the power to proceed monitoring during times of full sign loss, and an on-board rechargeable battery for a real-time clock, which drops the time-to-fix from round 26 seconds to simply two seconds.
The board contains Qwiic, USB Sort-C, and unpopulated header connection choices. (📷: SparkFun)
In addition to a Qwiic connector for I2C communication, additionally out there on devoted pins, the board contains a USB Sort-C connector with USB-TTL serial help, a 3.3V UART, and SPI — plus a second UART for RTCM correction messages and an SMA connector for an exterior antenna, not provided.
The board is now out there on the SparkFun retailer at $299.95 earlier than quantity reductions; extra info, together with antenna choices and particulars of the Arduino library, is offered from the board hookup information.
