ESP32‑C3 Core Development Board 4‑Layer Gold‑plated PCB Onboard 2.4G Antenna Type‑C Interface WiFi BLE Module For IoT Embedded DIY Project

CORE‑ESP32‑C3 Development Core Board

📌 Product Overview

The CORE‑ESP32‑C3 core board is built upon Espressif ESP32‑C3 chip, compact size only 21mm * 51mm. It adopts stamp‑hole edge design, convenient for secondary embedding integration. This board brings rich hardware peripherals including UART, GPIO, SPI, I2C, ADC, PWM interfaces. Two versions are available: Classic Version with serial chip for IDE debugging, and Lite Version without serial chip for mass‑production cost‑saving. It supports LuatOS, LuaPanda IDF, Arduino, MicroPython and other development frameworks. Only LuatOS obtains official technical support. 4‑layer gold‑plated PCB with onboard 2.4G PCB antenna, Type‑C USB interface for downloading and power supply.
