Espressif ESP32-C5-WROOM-1U-N8R8 Wi-Fi 6 & BLE Module

The module is fully supported by Espressif's official ESP-IDF (IoT Development Framework), which provides comprehensive libraries for Wi-Fi 6, Bluetooth LE, Zigbee, and Thread. It is also compatible with the Arduino Core for ESP32 via PlatformIO or the Arduino IDE, allowing for rapid prototyping. For MicroPython developers, a port is available, though full Wi-Fi 6 feature support may require the native IDF. Always check Espressif's GitHub repository for the latest stable release and migration guides from older ESP32 chips.

The module features a U.FL (IPEX) female connector for an external antenna. You will need a compatible U.FL to SMA pigtail cable or a direct U.FL antenna. Carefully mate the connector, ensuring a secure click. For optimal RF performance, use a 50-ohm antenna tuned for the 2.4GHz and/or 5GHz bands. Avoid bending the cable sharply near the connector. In your firmware, you typically do not need special configuration to use the external antenna, as the internal RF switch is managed automatically by the ESP-IDF's RF initialization routines.

Active current depends on RF mode; Wi-Fi 6 transmission can draw several hundred milliamps. For low-power designs, utilize the ESP32-C5's advanced sleep modes. Light-sleep maintains RAM and can achieve currents under 1mA, waking via GPIO or timer. Deep-sleep powers down most circuitry, retaining RTC memory, with currents in the microamp range, waking via external wake-up pins or RTC timer. Configure sleep using `esp_deep_sleep_start()` in ESP-IDF. Always ensure your 3.3V regulator has low quiescent current and use a high-quality timing crystal for accurate sleep durations.
