Seeeduino XIAO Expansion board

DESCRIPTION

A powerful expansion board for Seeeduino XIAO. It enables you with a quick and easy way for prototyping or complete your next big project. With its rich set of peripherals including an OLED, RTC, expandable memory, passive buzzer, RESET/User button, 5V servo connector, multiple data interfaces and Circuit python support, you could explore an infinite amount of possibilities with your Seeeduino XIAO.

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 pins led out. Convenient plug and play Grove connectors support multiple data protocols, including IIC, Uart and Analogue/Digital.
• Circuit Python Supported
• Mini Size: Compact and elegant making it perfect for tiny and wearable projects.

Included Peripherals

• OLED display: Visual data display without connecting to PC, which enables debugging in a more efficient way, and builds applications 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, enables maintaining accurate time when the main power is turned off.
• Expandable memory: With a mini SD card slot on the back, no worry about memory limit anymore when adding libraries and using circuit python.
• User button: Besides the RESET button, also provide another user-defined button.
• Passive buzzer: Same passive buzzer on Wio Terminal, with which you could change the PMW frequency to award different beep sounds to get a "buzzer music".
• Grove connectors: All pins 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.
