+    The macros EINK_DISPLAY_MODEL, EINK_WIDTH, and EINK_HEIGHT are defined as build_flags in a variant's platformio.ini
+    Previously, these macros were defined at the top of this file.
+
+    For archival reasons, note that the following configurations had also been tested during this period:
+    * ifdef RAK4631
