 # This file contains pin mappings for the SUNLU S8 v1.01 (circa 2020), which
 # is a modified RAMPS v1.3 board. To use this config, the firmware should be
 # compiled for the AVR atmega2560. The following pins are available for
-# expansion (e.g. ABL): ^ar19 (Z+ endstop), ar4, ar5, ar6, ar11
+# expansion (e.g. ABL): ^PD2 (Z+ endstop), PG5, PE3, PH3, PB5
 
 # See docs/Config_Reference.md for a description of parameters.
