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
