XIAO ESP32C6 is a cost-effective MCU based on Espressif’s ESP32-C6. This compact MCU excels in Matter-compliant smart home applications with its support for various wireless connectivity (2.4GHz Wi-Fi 6, BLE 5.0, Zigbee, and Thread). Designed with the thumb-size footprint and a single-sided mount of the XIAO Series, it's perfect for space-limited projects. Encrypted on the chip, the XIAO ESP32C6 ensures a desired level of security streamlined development experience, and swift market entry by integrating easily with major IoT Cloud platforms.
- Enhanced Connectivity: Combines 2.4GHz Wi-Fi 6 (802.11ax), Bluetooth 5(LE), and IEEE 802.15.4 radio connectivity, allowing you to apply the Thread and Zigbee protocols.
- Matter Native: Supports building Matter-compliant smart home projects thanks to its enhanced connectivity, achieving interoperability
- Security Encrypted on Chip: Powered by ESP32-C6, it brings enhanced encrypted-on-chip security to your smart home projects via secure boot, encryption, and Trusted Execution Environment (TEE)
- Outstanding RF performance: Has an on-board antenna with up to 80m BLE/Wi-Fi range, while reserving an interface for external UFL antenna
- Leveraging Power Consumption: Comes with 4 working modes, with the lowest being 15 μA in deep sleep mode, while also supporting lithium battery charge management.
- Dual RISC-V Processors: Incorporates two 32-bit RISC-V processors, with the high-performance processor running up to 160 MHz, and the low-power processor clocking up to 20 MHz
- Classic XIAO Designs: Remains the classic XIAO designs of the thumb-size form factor of 21 x 17.8mm, and single-sided mount, making it perfect for space-limited projects such as wearables
- Seamless integration with mainstream Cloud Platforms: ESP Rain Maker, AWS IoT, Microsoft Azure, and Google Cloud
