#Conceptual Design# Premier Expansion Board for SeeeduinoXIAO - Grove XIAO Plus - waiting for inputs

[reivilo]

@ming.wen Thank you for the detailed explanations.

@ming.wen

SAMD21 MCU already include an RTC but Seeeduino XIAO did not lead out the required pin for it, so it may be more practical to just add another RTC chip on board.

Maybe a revision of the Xiao board could add the missing connection.

So I vote for the following finalists:

• design III with a screen
• design C without a screen
