 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 9 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.
