ESP32-C3-WROOM-02-N4 – Compact Wi-Fi & BLE Module: Secure Connectivity with RISC-V Core and 4MB Flash
The ESP32-C3-WROOM-02-N4 is a powerful, low-power wireless module based on the ESP32-C3 SoC, featuring a single-core 32-bit RISC-V processor, integrated Wi-Fi (802.11 b/g/n), and Bluetooth 5 (LE). Equipped with 4MB external flash and a PCB antenna, it provides reliable performance in a cost-effective form factor. Designed for secure IoT applications, the ESP32-C3 supports AES, SHA-2, RSA, and ECC encryption, along with secure boot and flash encryption. Its compact size, robust RF performance, and low power consumption make it ideal for smart home devices, industrial sensors, wearables, and cloud-connected systems. Fully compatible with Espressif's open-source ESP-IDF development framework, it ensures smooth firmware development and over-the-air updates.
