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