Meet the SparkFun GPS-RTK Dead Reckoning Breakout - ZED-F9R , your go-to GPS module for precision navigation in tough environments. This cutting-edge GPS receiver fuses sensor data with GNSS signals from GPS, GLONASS, Galileo, and BeiDou, delivering an impressive 0.01-meter accuracy when paired with an RTK correction source. The ZED-F9R combines u-blox's Automotive Dead Reckoning (ADR) technology with a 3D IMU sensor, wheel tick data, vehicle dynamics models, and GNSS corrections to provide a continuous, reliable positioning solution—even in dense urban landscapes or areas with limited signal access.

The 184-channel u-blox F9 engine enables this module to operate with four GNSS systems at once, keeping you connected and precise in real-time at rates up to 30Hz. Whether you're navigating tunnels, parking garages, or urban canyons, this module guarantees you won't get lost.

Perfect for autonomous robotics, the ZED-F9R features a built-in Qwiic connector , meaning no soldering is required to hook it up to your system. However, the board also includes 0.1"-spaced pins for breadboard compatibility, offering ultimate flexibility. Want even more control? The module is fully configurable using u-center software or SparkFun's Arduino library , allowing you to tweak baud rates, update rates, geofencing, spoof detection, and more.

A cold start takes ~24 seconds, but thanks to the onboard rechargeable battery , you can enjoy hot starts in just ~2 seconds. The SparkFun ZED-F9R is a top-tier choice for anyone who demands precision and performance.

Good value, soft and comfortable
Color: Black, Army Green, Light Gray, Size: 4X-Large, Color: Black, Army Green, Light Gray, Size: 4X-Large
Initial thoughts are very positive with this 3 pack shirt set. The green is similar to an OD military green and the black and gray are standard color shades. Material is soft and sizes are true to size. The mock turtleneck isn’t too tight but may still be a little annoying to some people. I do question the amount of spandex in these shirts. Tag says 5% but these shirts are extremely stretchy and feels like a higher spandex content. It’s also a little tough to figure out which way is the front of the shirt. Visually rhe front does have a lower collar line than the back but would still be nice to have a brand tag printed in the back of the shirt for quicker identification. Overall for roughly $12 a shirt these are a good choice for everyday wear. I will update rating if these shirts fail to meet expectations after further use.

Just what I wanted.
Color: Black, Navy Blue, Wine Red, Size: 5X-Large
These may have just become my standard shirt to wear. Feels good whether tucked or out. Drapes well and fits well. So far, I can see it adjust to the different undershirt I may wear. Will probably order another set in other colors and a back up set of the basics because they will get worn a lot.

Its alright
Color: Black, Size: 5X-Large
True to size per the size chart. The fabric is soft but it it feels cheap to me. It attracts lint but you can brush it off easily so its not the cheapest material I've dealt with. Also, it is opaque (not see through). There is no front/ back indicator either which is indicative of a cheap shirt in my opinion. Would be friendly for tag sensitive people (to stay positive).
