## Hardware
-Both the **Heltec WiFi LoRa 32 V3** and **V4** are supported. These boards were chosen for their ample flash and LoRa capabilities. PSRAM availability varies — the V4 ships with 2 MB PSRAM, while the V3 uses the ESP32-S3FN8 which has **no PSRAM**. The firmware **detects PSRAM at runtime** and allocates the TLSF memory pool from SPIRAM when available, falling back to internal SRAM (~170 KB) on boards without PSRAM.
