Nordic nRF52840 (ARM Cortex-M4, Adafruit nRF52 Arduino core)

• Seeed Wio Tracker L1 — board definition at boards/seeed_wio_tracker_l1.json, linker script and variant files under boards/seeed_wio_tracker_l1/. Pin/peripheral header: src/include/boards/seeed_wio_tracker_l1.h.
  • Environments: local_wio_tracker_l1, local_wio_tracker_l1_encrypted, local_wio_tracker_l1_bletest, prod_wio_tracker_l1.
  • Uses Adafruit LittleFS (InternalFileSystem) for flash-backed identity/config storage rather than EEPROM.h (not available on this core).

Espressif ESP32 (Arduino core)

• Heltec WiFi LoRa 32 (V2/V3/V4) — src/include/boards/heltec_wifi_lora_32_V2.h, ..._V3.h (V4 shares the V3-family config).
  • Environments: prod_heltec_wifi_lora_32_V2/V3/V4, local_heltec_wifi_lora_32_V2/V3/V4, local_heltec_wifi_lora_32_V3_encrypted, test_heltec_wifi_lora_32_V3.
• LilyGO T-Beam (SX1262 and SX1276 radio variants) — src/include/boards/lilygo_t_beam_sx1262.h, ttgo_t_beam_v1_sx1276.h, ttgo-t-beam.h; also lilygo_t_beam_supreme_sx1262.h and lilygo_sim7000g_lora.h for other T-Beam variants.
  • Environments: prod_lilygo_t_beam_sx1262, prod_lilygo_t_beam_sx1276, local_lilygo_t_beam_sx1262, local_lilygo_t_beam_sx1276.
• TTGO LoRa32 V1.3 — prod_ttgo_lora32_v1_3, local_ttgo_lora32_v1_3.

Base/shared configuration for ESP32 environments lives in [env:release_cdp]/[env:local_cdp].

examples/External-Boards-Example/DuckLink/platformio.ini also defines a standalone heltec_wifi_lora_paper environment, demonstrating how to build this library against a board not otherwise wired into the main platformio.ini.

See Getting Started for how EXAMPLE_DIR selects which sketch a given environment actually compiles.
