ESP32-C3 Super Mini Development Board (HW-466AB) – RISC-V WiFi + Bluetooth 5.0 IoT Board in Pakistan

Overview

The ESP32-C3 Super Mini (Model HW-466AB) is a thumbnail-sized development board designed for the next generation of IoT. Unlike the classic ESP32, the C3 uses the open-source RISC-V architecture, offering better power efficiency and modern security features. With its integrated WiFi and Bluetooth 5.0 (LE), it is the perfect choice for battery-powered smart home nodes, tiny robots, and “invisible” electronics projects.

Key Features

• Ultra-Tiny Footprint: About the size of a coin, making it easy to hide in small enclosures or wearable gear.

• Modern RISC-V Core: Faster and more efficient than the old ESP8266, running at a crisp 160MHz.

• Native USB-C: No more hunting for old micro-USB cables! Features a modern Type-C port for both power and high-speed programming.

• Dual Connectivity: Supports 2.4GHz WiFi and Bluetooth 5.0 (LE) for long-range and low-energy communication.

• 4MB Flash: Plenty of space for your Arduino code, MicroPython scripts, or ESP-IDF firmware.
