Are you looking to buy a Seeed Studio Xiao ESP32C3 Tiny MCU Board in Australia?

Seeed Studio XIAO ESP32C3 is a thumb-sized microcontroller, equipped a highly-integrated ESP32-C3 chip, built around 32-bit RISC-V operating up to 160 MHz. By 2.4GHz Wi-Fi and BLE wireless capabilities, along with low-power cost and charging ability, it provides a perfect solution for various IoT controlling scenarios and wearable device applications.


  • Outstanding RF performance:  Powerful ESP32-C3 SoC and U.FL antenna provided that supports WiFi/Bluetooth connection over 100m. 
  • Thumb-size Design: 21 x 17.5mm overall dimension, portable and lightweight. 
  • Low power consumption: Lowest as 44 μA (deep sleep mode), with 4 working modes available.
  • Onboard battery charge IC: Supports battery charging, great for various wearable scenarios and wireless IoT applications.
  • Ready for productization:  Single-sided components design, easily integrated into other boards and Seeed provides Fusion Service for rapid production.


Behold, here is a new member to the Seeed Studio XIAO series, like a Thumbelina carrying a complete Wi-Fi system along with Bluetooth Low Energy function - the Seeed Studio XIAO ESP32C3 has launched!

Seeed Studio XIAO ESP32C3 has equipped a highly-integrated ESP32-C3 chip, built around 32-bit RISC-V chip processor with a four-stage pipeline that operates at up to 160 MHz. Remaining the Seeed Studio XIAO series classic form-factor of small and exquisite, it offers 2.4GHz Wi-Fi and BLE(Bluetooth Low Energy) wireless capabilities to the developers. With the addition of ultra-low-power cost and charging ability, it provides a perfect solution for various IoT controlling scenarios and complex carriable applications.

As you may see, 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 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.

Application 1: Smart Private Garage

Materials: XIAO ESP32C3 *2, Grove - Button *1, Grove - Relay*1


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.


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


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.


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 LoRa-to-MQTT bridge as well.  

Seeed Fusion is launching a DIY XIAO Mechanical Keyboard Contest based on Seeed Studio XIAO Series! Show us your XIAO keyboard creations for a chance to win $1000 in prizes and Seeed XIAO Pillows!!! To join the contest.
