+"""Allows useful indirection to test Pin naming logic by switching platform in testing
+    or provide bootstrapping logic for board identification where auto-detection is not
+    feasible (e.g. multiple ESP8266 boards architecturally identical). Once runtime
+    environment is established, can choose various routes to make available and re-export
+    common modules and operations, depending on platform support
