Description
The ESP32-C3 Super Mini is an ultra-compact WiFi and Bluetooth development board built around the RISC-V single-core ESP32-C3 chip — delivering impressive wireless performance in one of the smallest form factors available. With its Type-C USB port, built-in antenna, and low power consumption, this tiny board punches well above its size for IoT projects, smart home devices, and wireless sensor nodes.
Designed for space-constrained builds where every millimetre counts — the ESP32-C3 Super Mini fits into enclosures, wearables, and PCB designs that a standard dev board simply cannot.

🔧 Features & Specifications
🔧 Driver & Board Setup Guide
The ESP32-C3 Super Mini uses a built-in USB serial interface via the ESP32-C3 chip itself. On most systems it is detected automatically, but if your PC does not recognise it you may need the CH343 or CP2102 driver depending on your board revision.
Install Driver (If COM Port Does Not Appear)
Plug in via Type-C and check Device Manager. If no COM port appears, download the CP210x driver from Silicon Labs (works for most versions).
Add ESP32 Board Package to Arduino IDE
Go to File → Preferences → Paste in Additional Boards Manager URLs:
https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json
Then Tools → Boards Manager → Search esp32 → Install esp32 by Espressif Systems (version 2.0.0 or higher).
Select Board & Port
Go to Tools → Board → ESP32 Arduino → ESP32C3 Dev Module. Then select the correct COM port under Tools → Port. You are ready to upload.
⚙️ Arduino IDE Settings — WiFi & Bluetooth Setup
💡 Bluetooth Tip: The ESP32-C3 supports BLE only — it does NOT support Classic Bluetooth Serial like the original ESP32. Use
BLEDevice.h library for all Bluetooth communication on this board.💻 Quick Start — Example Code
Example 1 — WiFi Connection
#include <WiFi.h> const char* ssid = "Your_WiFi_Name"; const char* password = "Your_WiFi_Password"; void setup() { Serial.begin(115200); WiFi.begin(ssid, password); Serial.print("Connecting"); while (WiFi.status() != WL_CONNECTED) { delay(500); Serial.print("."); } Serial.println("\n✅ Connected! IP: "); Serial.println(WiFi.localIP()); } void loop() {}
Open Serial Monitor at 115200 baud. Make sure your WiFi is 2.4GHz — C3 does not support 5GHz.
Example 2 — Bluetooth LE Advertise
#include <BLEDevice.h> #include <BLEAdvertising.h> void setup() { Serial.begin(115200); BLEDevice::init("Dream RC C3 Mini"); BLEAdvertising* pAd = BLEDevice::getAdvertising(); pAd->start(); Serial.println("✅ BLE Advertising!"); Serial.println("Find 'Dream RC C3 Mini' on nRF Connect"); } void loop() {}
⚠️ C3 supports BLE only — Classic Bluetooth Serial (BluetoothSerial.h) is NOT available on this board.
