Adafruit has announced the Adafruit QT Py, a compact SAMD21-based board, reminiscent of the Xiao.
Surprisingly, the pinout is the same with 14 castellated pins.
- Same size, form-factor, and pin-out as Seeed Xiao
The interesting changes include an SPI Flash memory (perfect for Python), a connector (STEMMA QT, a competitor of the Grove system), a RESET button and an RGB LED.
The price hasn’t been disclosed yet.

I love that the Xiao is becoming a “standard form factor” as it’s such a great little size for projects.
I have to admit, the QT Py definitely has the edge for me right now just for having a slightly more sane amount of memory. The Xiao is kind of a pain to work with if you use Circuit Python. The stemma connect is also awesome - Adafruit have so many great sensors in the stemma format. AND they daisy chain super easily!
Seeeduino - time to up your game and release a Xiao 2.0 that’s even better 
That was the message!
