Description

This is SeedStudio Seeeduino XIAO Expansion Board.
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 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.
Hardware Overview:

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 mini SD card slot on the back, no worry about memory limit any more 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 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.

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, onboard 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. Mini SD 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.
