Seeed Studio XIAO ESP32C3 featuring ESP32C3 carries a complete Wi-Fi system along with Bluetooth Low Energy function. With its exquisite design and WiFi+BT ability, it’s perfect for various IoT controlling scenarios and complex carriable applications.

Features

  • 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.

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.

Getting Started

Since the ESP32C3 chip does not have support for native USB, you won’t see a CIRCUITPY drive appear when you plug it into your computer. Here is a complete guide for getting Circuitpython installed onto an ESP32C3 device, and for enabling Web Workflow so you can load your Python code onto it.

CircuitPython 9.1.0-beta.1

This is the latest development release of CircuitPython that will work with the Seeed Studio XIAO ESP32C3.

Alpha development releases are early releases. They are unfinished, are likely to have bugs, and the features they provide may change. Beta releases may have some bugs and unfinished features, but should be suitable for many uses. A Release Candidate (rc) release is considered done and will become the next stable release, assuming no further issues are found.

Please try alpha, beta, and rc releases if you are able. Your testing is invaluable: it helps us uncover and find issues quickly.

Absolute Newest

Every time we commit new code to CircuitPython we automatically build binaries for each board and language. The binaries are stored on Amazon S3, organized by board, and then by language. These releases are even newer than the development release listed above. Try them if you want the absolute latest and are feeling daring or want to see if a problem has been fixed.

Previous Versions of CircuitPython

All previous releases of CircuitPython are available for download from Amazon S3 through the button below. For very old releases, look in the OLD/ folder for each board. Release notes for each release are available at GitHub button below.

Older releases are useful for testing if you something appears to be broken in a newer release but used to work, or if you have older code that depends on features only available in an older release. Otherwise we recommend using the latest stable release.
