Seeed Studio XIAO ESP32-C3

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.

Features

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. 

• Outstanding RF performance:  Powerful ESP32-C3 SoC and an included U.FL antenna 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 productisation:  Single-sided components design, easily integrated into other boards and Seeed provides Fusion Service for rapid production.
