Seeeduino XIAO Expansion board (SE-103030356)

A powerful functional expansion board for Seeeduino XIAO of only half Raspberry Pi 4 size. It enables build prototype and project in easy and quick way. With its rich peripherals including OLED, RTC, expandable memory, passive buzzer, RESET/User button, 5V servo connector, multiple data interfaces… you could explore infinite possibilities of Seeeduino XIAO. Circuit python is also well supported by this board.

Key Features

Quick Prototyping: Easy debug and Reset with RESET button and SWD pin led out to the male header. 0.96” OLED, enables visual data to display without PC serial monitor.

Rich peripherals: OLED display, RTC, expandable memory space, passive buzzer, user button, on board battery management chip… One board on hand to explore infinite possibilities of Seeeduino XIAO.

No Soldering Needed: All pin led out. Convenient plug and play Grove connectors support multiple data protocols, including IIC, Uart, Analog/Digital.

Circuit Python Supported: Well supports circuit python. MicroSD card slot enables memory space to expand, making it possible to allocate more libraries needed in prototyping and project building.

Mini Size: Compact and elegant with only half Raspberry Pi 4 size, perfect for tiny and wearable projects.

Hardware Overview

Many users adore Seeeduino XIAO because of its mini size and elegant design, so we try our best to keep the size as mini as we could when persuing the powerful function and rich interfaces. As you could see, the board is of only half Raspberry Pi 4 size.

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.

Though with all these rich peripherals, you may find Seeeduino XIAO Expansion Board also has very high-cost performance as Seeeduino XIAO does.
