Description

Seeeduino XIAO Expansion Board is a powerful functional expansion board for Seeeduino XIAO of only half Raspberry Pi 4 size. It enables build prototype and project in an easy and quick way. With its rich peripherals, you could explore infinite possibilities of Seeeduino XIAO. Circuit python is also well supported by this board.

Rich peripherals on board including

OLED display: Visual data display without connecting to PC, which enables debug in a more efficient way, and builds application such as a sensor hub, data monitor system, .etc
RESET button: No more jumper wire and short circuit, easy reset with just one click.
SWD debug: SWD pin led out as male pin header, making debugger connection and firmware download much easier.
High precision RTC: High precision real-time clock with battery backup, enable maintain accurate time when the main power is turned off.
Expandable memory: With a MicroSD card slot on the back, no worry on memory limit any more when adding libraries and using circuit python.
User button: Besides the RESET button, also provide with another user-defined button.
Passive buzzer: Same passive buzzer on Wio Terminal, with which you could change the PMW frequency to award different beep sound to get a "buzzer music".
Grove connectors: All pin led out, plug and play grove connectors support common data protocols (Grove IIC2, Grove UART1, A0/D0 Grove*1)
Lipo Battery Charging: JST2.0mm standard lipo battery connector and battery management system, supports both USB and lipo battery power supply, and easy onboard battery recharge.
5V servo connector: 5V output led out to male header for 5V servo and sensor connection.
