Description
Seeed Studio XIAO ESP32C3 has equipped a highly-integrated ESP32-C3 chip, built around a 32-bit RISC-V chip processor with a four-stage pipeline that operates at up to 160 MHz.
The board equips highly-integrated ESP32-C3 SoC. The chip has been installed with a complete 2.4GHz Wi-Fi subsystem which means it supports Station mode, SoftAP mode, SoftAP & Station mode, and promiscuous mode for multiple Wi-Fi applications. It works under an ultra-low power state, also supporting features of Bluetooth 5 and Bluetooth mesh. There are 400 KB SRAM & 4 MB Flash on the chip, allowing for more programming space, and bringing more possibilities to the IoT control scenarios.
Being a number to the Seeed Studio XIAO family, the board deservedly maintains the classic thumb-sized form-factor design and elegant productization of single-sided components mounting. Meanwhile, it has equipped with a battery charge chip and integrated circuit for enhancing its ability to carry. This board comes included with an external antenna to increase the signal strength for wireless applications. There are 11 digital I/O that can be used as PWM pins and 4 analog i/o that can be used as ADC pins. It supports UART, IIC, and SPI serial communication ports, also including IIS (Internet Information Services). Utilizing its small and exquisite hardware design and the powerful onboard chip, programming by Arduino, it will offer more ability to wearable and portable devices or other applications.
To provide a more smoothed learning experience for beginners, we have prepared a free course based on the Starter Kit for Seeed Xiao which contains 4 Units and 16 lessons to help you quickly get started with development boards, and then you can proceed to realize little and individual fun projects.
You can have access to the Seeed Studio Grove ecosystem by connecting it to the compatible Seeed Studio XIAO expansion board. We have developed more than 400 Grove modules, covering a wide range of applications that can fulfill various needs. Get started and explore the infinite possibilities of the Seeed Studio XIAO series!
If you are interested in programming embedded machine learning, we have Codecraft visual programming that can help you quickly start your own TinyML project. And we have set up a #tinyml channel on our Discord server, please click to join for 24/7 making, sharing, discussing, and helping each other out.
We already have 5 XIAO products based on different solutions in the XIAO family, to help you better understand the differences and choose the most suitable part for your projects, please refer to the Seeed Studio XIAO Series Page.
Attention
- It will be a little hard to connect the antenna at the first time using the board.
- Please connect the antenna at the vertical direction and do not drag at the horizontal direction.

Application
- Internet of Things
- Wearable devices
- Health monitoring
- Education
- Low-Power(LP) networking
- Rapid prototyping
Application 1: Smart Private Garage
Materials: XIAO ESP32C3 *2, Grove - Button *1, Grove - Relay*1
Description:
This is a peer-to-peer WiFi communication application, since two XIAOs detect each other via Wifi, the garage door will open or keep opening, and vice versa.
Improvement:
It is nice to add an ultrasonic distance sensor to measure the car-to-door distance and an OLED screen to check the status of the garage. If you want an onboard voice 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. This wearable device can be used as a simple GPS-Tracker which will lock its current location and publish other data via 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, the chip ESP32-C3 allows this tracker to communicate over WiFi or BLE, and therefore, we can upload the tracker’s data or realize the Long Range-to-MQTT bridge as well.
