QT Py SAMD21 - evaluation board with ATSAMD21E18 microcontroller

Description

The evaluation board is equipped with an ATSAMD21E18 microcontroller with ARM Cortex M0+ core, which can operate at 48 MHz, has 256 KB of Flash memory and 32 KB of RAM. It has the shape and dimensions compatible with the Seed Xiao boards and the Stemma QT connector, which allows you to connect additional modules with sensors or a display. It uses a USB type C connector for programming and communication with a PC, has a built-in RGB NeoPixel LED and a 3.3 V stabilizer with a capacity of 600 mA. On the edges of the board, there are connectors with 11 GPIO pins, on which the user will find UART, SPI, I2C, I2S interfaces, PWM outputs and analog inputs and outputs. In addition, there are 6 inputs for operating the touch buttons. At the bottom of the board, there are pads for soldering SPI Flash memory needed for more demanding projects. The kit can be programmed in Arduino IDE or CircuitPython. Thanks to its small dimensions, it will be used in projects where small size is of key importance. Full documentation with examples of use is available on the product page.
