FireBeetle 2 ESP32-C5-U (N4) IoT Development Board (Dual-Band Wi-Fi 6)

This FireBeetle 2 ESP32-C5-U(N4) development board is a compact low-power IoT platform based on the Espressif ESP32-C5-WROOM-1U-N4 module. Combining a 240 MHz single-core RISC-V processor, 4 MB Flash, dual-band Wi-Fi 6, Thread 1.3, Zigbee 3.0 and flexible power management, this ESP32-C5 development board is designed for smart home, industrial IoT, wireless sensing and battery-powered edge device projects.

2.4 GHz + 5 GHz Dual-Band Wi-Fi 6 for More Flexible Wireless Deployment

This ESP32-C5 development board supports both 2.4 GHz and 5 GHz Wi-Fi bands with IEEE 802.11a/b/g/n/ac/ax compatibility. The 5 GHz band provides an additional option for applications that benefit from higher throughput, lower latency and reduced interference compared with crowded 2.4 GHz environments. Wi-Fi 6 features such as OFDMA and Target Wake Time also help improve network efficiency and support lower-power connected applications.

U.FL External Antenna Connector for Enclosed IoT Devices

This FireBeetle development board uses a U.FL (IPEX) external antenna connector, allowing the antenna to be positioned outside metal enclosures, electrical cabinets or waterproof housings where radio signals may otherwise be attenuated. The connector supports external 2.4 GHz / 5 GHz dual-band antennas for flexible antenna selection and mounting. The package includes a 2.4GHz communication FPC antenna.

Thread 1.3, Zigbee 3.0 and Matter-Oriented Smart Home Development

This wireless IoT development board supports Wi-Fi, 2.4 GHz low-power wireless communication and IEEE 802.15.4, including Thread 1.3 and Zigbee 3.0. This protocol combination supports development of Matter over Wi-Fi or Thread end devices for cross-platform smart home projects. When paired with an external MCU, this ESP32-C5 platform can also be used in Thread Border Router, Matter Gateway or Zigbee Bridge development scenarios.

Solar Charging, Battery Monitoring and 21 μA Deep Sleep

This low-power IoT development board supports USB Type-C power, 5 V DC input and 4.5–6 V solar panel input for Li-ion battery charging. The power management design uses the same solar power management IC as the DFRobot 5 V@1 A Solar Power Manager and supports battery voltage monitoring. A switchable 3.3 V output can disconnect external sensors when inactive, while the 21 μA deep-sleep current under battery power helps reduce standby energy consumption in long-term wireless monitoring applications.

Compact Expansion Platform for Sensors, Displays and Wireless Nodes

This ESP32-C5 board measures 25.4 × 60 mm and provides 18 digital I/O, SPI, UART, I2C, I2S, ADC, PWM and infrared transceiver resources, together with an onboard GDI connector and PH2.0 Li-ion battery connector. Support for C/C++ and MicroPython makes this platform suitable for indoor air quality monitoring, balcony plant monitoring, smart home IoT, wireless sensor nodes, Matter devices, Zigbee gateway development and Home Assistant projects.
