Hello,
On the carrier board is a possilbility to attach a SPI flash. Do you plan to release an ArduPy firmware which uses that flash in near furture? Or if I try to write it by myself (using Wio Terminal firmware and some other CircuitPython firmwares as a template) do you have some hints to share?
Thank you
Of course, when XIAO’s Carrier Board is released, we will definitely add it. @jahr
As far as I know it has been released. At least I already received few of them some time ago 
Is it true? What is it like? I don’t know yet. @jahr
It’s called Grove Shield for Seeeduino XIAO - https://www.seeedstudio.com/Grove-Shield-for-Seeeduino-XIAO-p-4621.html.
