## Description

## Overview

The LILYGO T-Beam BPF is a T-Beam platform variant integrating an ESP32-S3 dual-core processor, LoRa radio, and a dedicated Band Pass Filter (BPF) tuned for the 144–148 MHz amateur radio VHF band. The BPF reduces out-of-band interference and improves receiver selectivity, making it ideal for APRS, amateur radio telemetry, and LoRa mesh networks in the 2-meter band. The board includes a 0.96" SSD1306 OLED display (128×64), AXP2101 PMU for battery management, 16MB flash, and 8MB PSRAM. Power supply options, Boot, Reset, and Power buttons are included onboard.
