The Seeed XIAO ESP32C3 has 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 member of the Seeed XIAO family, the board maintains the classic thumb-sized form-factor design and single-sided component mounting. Meanwhile, it is equipped with a battery charge chip and integrated circuit. This board has 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 analogue i/o that can be used as ADC pins. It supports UART, IIC, and SPI serial communication ports, also including IIS (Internet Information Services).
This comes in two options: Board Only or With Soldered Headers. Please choose which one you want before adding it to your cart!
