 **Note:** There are a variety of compile guards (COMPILE_WIFI, COMPILE_AP, etc) at the top of RTK_Everywhere.ino that can be commented out to remove them from compilation. This will greatly reduce the firmware size and allow for faster development of functions that do not rely on these features (serial menus, system configuration, logging, etc).

+The u-blox ZED-F9P is the GNSS receiver inside the RTK EVK. The RTK EVK also contains the u-blox NEO-D9S for receiving L-Band corrections. The following describes how to update the firmware on the ZED-F9P and NEO-D9S modules.
 
 The firmware loaded onto the ZED-F9P and NEO-D9S receivers is written by u-blox and can vary depending on the manufacture date. The RTK Firmware (that runs on the ESP32) is designed to flexibly work with any u-blox firmware. Upgrading the ZED-F9x/NEO-D9S is a good thing to consider but is not crucial to the use of RTK products.

+The UM980 is the GNSS receiver inside the RTK Torch. The following describes how to update the firmware on the UM980.
+
 1. Download the latest UM980 firmware. As of writing, the UM980 firmware is [v11833](https://raw.githubusercontent.com/sparkfun/SparkFun_RTK_Torch/main/UM980_Firmware/UM980_R4.10Build11833.pkg). See the [RTK Torch repo](https://github.com/sparkfun/SparkFun_RTK_Torch) for the latest firmware.
 
 2. Download and install [UPrecise](https://raw.githubusercontent.com/sparkfun/SparkFun_RTK_Torch/main/UM980_Firmware/uprecise-v2-0.exe). UPrecise is the software created by Unicore to configure and view output from Unicore GNSS modules. v2 of the software can be downloaded [here](https://raw.githubusercontent.com/sparkfun/SparkFun_RTK_Torch/main/UM980_Firmware/uprecise-v2-0.exe) but newer versions may be available.
