## Description

## Overview

The LILYGO T8-C3 is a compact development board built around the ESP32-C3, a 32-bit RISC-V single-core processor with integrated Wi-Fi (802.11 b/g/n) and Bluetooth 5.0 + BLE. The board includes a TF (microSD) card slot, onboard battery power detection, and a JST 1.25mm 2-pin connector for Li-Po battery. It uses USB Type-C for power and data, but requires the companion T-U2T adapter for USB-to-serial programming. It supports a 3D WiFi ceramic antenna by default and can be reconfigured for an external IPEX antenna by adjusting a resistor. Compatible with Arduino IDE, ESP-IDF, and MicroPython.
