GBEasy to find layout and schematics Easy to find layout and schematic, in better than pdf or Gerber (i.e editable eagle files). This saves the additional steps is having to search for these open source files on git (like SparkFuns' competitor mandates)

GBGreat 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.

CASparkfun 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.

AUI have enjoyed the resources I have enjoyed the resources, but I haven't really purchased that much. I do tend to use the resources though, and I think you contribute generously to the electronics/arduino community.
