-This folder contains the various firmware versions for RTK Surveyor. Each binary is created by exporting a sketch binary from Arduino. The sketch binary is then uploaded to the ESP32 along with boot_app0.bin, RTK_Surveyor.ino.bootloader.bin, and RTK_Surveyor.ino.partitions.bin. You can update the firmware on a device by loading a binary onto the SD card and inserting it into the RTK Surveyor (see more information [here](https://learn.sparkfun.com/tutorials/sparkfun-rtk-surveyor-hookup-guide/firmware-updates-and-customization)) or by using the following CLI:
