This is a powerful functional expansion board for Seeeduino XIAO. It enables you to quickly build prototypes and projects with its rich peripherals including OLED, RTC, expandable memory, passive buzzer, RESET/User button, 5V servo connector and multiple data interfaces… allowing you to explore the infinite possibilities of the Seeeduino XIAO.
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 a PC serial monitor
Rich peripherals: OLED display, RTC, expandable memory space, passive buzzer, user button, onboard battery management chip… One board 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, Analog/Digital
Circuit Python Supported: 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
Product number: Seeed 103030356
Feature Details
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.
