Sparkfun surveyor/gnss reference station Great product…set the fp9 up with esp32 thing+ uploading data to rtk2go (free) and used the surveyor with an android phone over BT (doesn’t play well with iPhones). Designed layout in qgis (free) and staked out in swmaps (free)…worked perfectly for laying out a vineyard with a awe inspiring degree of accuracy.

Great experience with Sparkfun My experience with Sparkfun is so good because they always have excellent tutorials and code examples for the gear I buy from them. Although my applications are often unique, their stuff is practically plug and play.

SparkFun is my preferred parts and… SparkFun is my preferred parts and component supplier. Part of the goodness comes from the fact that I can get stuff in a day or two (I live in Arvada Colorado). My only complaint is occasionally they'll use a complex part whose manual is covered under an NDA from the manufacturer. This makes it difficult to impossible to open source my code that uses it.

It's better than Popular Electronics Magazine Enjoy reading about the latest new technology offering that brings high technology to the hobbyist at a reasonable price. Even though I may not want it just now, I could get it if I wanted to!
