Product description: Adafruit QT Py - SAMD21 - Adafruit 4600 microcontroller board
The small size Adafruit QT Py board is based on the popular SAMD21 chip . Its dimensions are the same as Seeed Xiao - 23.5 x 17.5 x 3.5 mm. The board outputs are also compatible with Seeed Xiao. The ATSAMD21E18 microcontroller has a 32-bit ARM Cortex M0 + core clocked at 48 MHz, 256 KB of Flash memory and 32 KB of RAM memory. The board is equipped with a USB type C socket for powering and programming the board. Additionally, the QT Py has a Qwiic / Stemma QT socket for simple prototyping and a programmable RGB NeoPixel LED and a Reset button. The board can be used with the Arduino IDE and CircuitPython.
