If you're in need of high precision positioning, look no further than utilizing the power of real time kinematics (RTK). We now have a full page of resources for all your RTK questions!
Whether it’s exploring uncharted caves in France or contributing to an open source street-mapping project, Eric Sibert relies on the SparkFun RTK Express for the positional accuracy he needs.
This week we have two new GPS-RTK Kits featuring the ZED-F9P and the ZED-F9R as well as two new ESP32 WROOM Dual Antenna products!

The story goes that George Antheil was madly in love with Hedy Lamarr and this was an attempt to gain her interest. There are no documents…
I know a guy who is a big "fan" of IoT, even though he's not all that technical. His "day job" is as a business attorney, so he can afford a…
That's true, the blue LEDs would ideally have a resistor closer to 4x than 2x when jumping from 3.3V to 5V. I don't remember my original…
Thanks for your reply! Your "roughly double" resistances for 5V vs 3.3V imply that the difference between LED drop and 3,3V is same as 3,3V…
Your right, that would be a great way to fine tune the current for LEDs! You're also correct that the goal of this project was finding the…
Hi there! For the sake of brevity, I didn't go into full detail about how exactly I calculated the 5V resistor values. But in short, I took…
Responding to your note about the highly non-linear relationship between the pot position and the current -- a way to address this would be…
Really great article. I'm a high school computer science teacher and this is a great resource both for us but also for our First Nations…
