 ### A note about ZED-F9P firmware
 
-The firmware loaded onto the ZED-F9P receiver is currently one of two versions: v1.12 or v1.13. All field testing and device specific performance parameters were obtained with v1.12.
+The firmware loaded onto the ZED-F9P receiver can vary depending on manufacture date. Currently one of three versions: v1.12, v1.13, and v1.30. All field testing and device specific performance parameters were obtained with v1.30.
 
 v1.12 has the benefit of working with SBAS and an operational RTK status signal (the LED illuminates correctly).
 
 v1.13 has a few RTK and receiver performance improvements but introduces a bug that causes the RTK Status LED to fail when SBAS is enabled.
 
+v1.30 has a few RTK and receiver performance improvements, I<sup>2</sup>C communication improvements, and most importantly support for Spartan PMP packets.
+
+The RTK Firmware is designed to work with any ZED-F9x firmware. Upgrading the ZED-F9x is a good thing to consider but is not crucial to the use of the RTK products.
+
