LILYGO provides ESP-IDF framework support using VS Code with various firmware and code examples. Resources are available on GitHub, including PDF schematics and additional tools. Some firmware, like MeshCore, has been ported to the devkit, with full support for ESP32-P4 targets in progress.
The T-Display-P4 is available on AliExpress for about $111 (TFT) or $136 (AMOLED) with an SX1262 830-945MHz LoRa transceiver. The TFT version is also on Amazon for $104. The package includes a T-shaped LoRa antenna, but no details on a battery, so it might not be included.
