ESP32C6
Seeed Studio XIAO ESP32C6 is powered bythe highly-integrated ESP32-C6 SoC, built on two 32-bit RISC-V processors, with ahigh-performance (HP) processor with running up to 160 MHz, and a low-power (LP) 32-bit RISC-V processor, which can be clocked up to 20 MHz. There are512KB SRAM and 4 MB Flash on the chip, allowing for more programming space, and bringing more possibilities to the IoT control scenarios.
XIAO ESP32C6 is Matter native thanks to its enhanced wireless connectivity. The wireless stack supports 2.4 GHz WiFi 6, Bluetooth® 5.3, Zigbee, and Thread (802.15.4). As the first XIAO member compatible with Thread, it's a perfect fit for building Matter-compliant projects, thus achieving interoperability in smart-home.
To better support your IoT projects, XIAO ESP32C6 not only provides seamless integration with mainstream cloud platforms like ESP Rain Maker, AWS IoT, Microsoft Azure, and Google Cloud, but also leverages security for your IoT applications. With its on-chip secure boot, flash encryption, identity protection, and Trusted Execution Environment (TEE), this tiny board ensuresthe desired level of securityfor developers looking to build smart, secure, and connected solutions.
This new XIAO is equipped with a high-performanceonboard ceramic antenna with up to 80m BLE/Wi-Fi range, while it also reserves an interface for an external UFL antenna. At the same time, it also comes with an optimized power consumption management. Featuring four power modes and an onboard lithium battery charging management circuit, it works in the Deep Sleep mode with a current as low as 15 µA, making it an excellent fit for remote, battery-powered applications.
Being the 8th member of the Seeed Studio XIAO family, XIAO ESP32C6 remains the classic XIAO design. It is designed to fit the 21 x 17.5mm, XIAO Standard Size, while remains its classic single-sided components mounting. Even being thumb-sized, it amazingly breaks out15 totalGPIO pins, including 11 digital I/Os for PWM pins and 4 analog I/Os for ADC pins. It supports UART, IIC, and SPI serial communication ports. All these features make it a perfect fit for either space-limited projects such as wearables, or a production-ready unit for your PCBA designs. (check out ourFusion one-stop prototyping and manufacturing services to explore what support you can get!).
Note
Please note that the classic pin heads for XIAO are not included in this product as we want to avoid component wastes (we got this input from the community and we want to contribute a bit to a greener earth). If you want to equip your XIAO ESP32C6 with the pinheads, you canclick here to add it to your cart with ease.
It's super developer-friendly to get started with XIAO ESP32C6 too. Compatible with both Arduino and ESP-IDF, it offers developers the way you prefer to tinker around. Moreover, we also provide the starter kit along with courses for beginners to quickly tap into the world of electronics.

Application 1: Smart Private Garage
Materials:XIAO ESP32C3 *2,Grove - Button*1,Grove - Relay*1
Description:
This is a peer-to-peerWiFicommunicationapplication,since two XIAOs detect each othervia Wifi, the garage door will open or keep opening, and vice versa.
Improvement:
It is nice to add anultrasonic distance sensor to measure the car-to-door distance and an OLED screen to check the status of the garage. If you want an onboardvoice sensor to command the door to open with vocal instruction, try our XIAO BLE Sense.
Application 2: Remote Forest Tracker
Materials:XIAO ESP32C3 *1,Grove - LoRa E5 *1,Grove - GPS*1
Description:
Thanks to the tiny size of the XIAO series, it is suitable to make the wearable devices, such as a small pet tracker. Thiswearabledevice can be used as a simple GPS-Tracker which willlock its currentlocation andpublishother datavia LoRa.
Improvement:
A compass that shows direction and distance is a great added value to the tracker that you could consider. Meanwhile, publishing altitude, speed, or other parameters could bring more scenarios to this tracker. Besides,thechipESP32-C3 allowsthis tracker to communicate over WiFi or BLE, and therefore,wecan upload the tracker’s data or realizethe Long Range-to-MQTT bridge as well.
