The Adafruit QT PY SamD21 board brings you the power of a SamD21 in one of the smallest form factor. Size and pinout is compatible with the Seeeduino XIAO board, but has more features : a reset button, a Neopixel RGB Led, and a STEMMA QT I2C connector.

Thanks to Node Blue, this board enables connecting buttons, switches, encoders, potentiometers,  rotary switches, joysticks  and various sensors.

By choosing the Bodac option, you'll be able to connect 5 buttons on only one input.

For example :

- with 2 encoders, 11 buttons instead of 7.

- without encoders, 15 buttons instead of 11.

 

Attention, this board uses an USB-C connector.

    Packages for using Node Blue. Packages are bound to a board, so you'll have to buy them for each board you wish to program. Only boards proposed on ElectroSeed shop are supported.

    Standard parckage includes the modules listed in the description.

    "Gaming Device" option allows to program the board so it will be seen by the PC as a standard gaming device (no drivers to install). To choose freely the device name, you must choose the Pro package.

    "Display" option gives you access to all the modules that deals with display : RGB Leds, 7 segments displays, Nextion screens, TFT/Oleds/etc. screens.

    Bodac Pack
    Bodac Pack

    The Bodac is a system that allows to implement several buttons on a single analog input, with the possibility to have several buttons pressed at the same time. The "usual" systems (resistors ladders or matrix without diodes), do not allow to press several buttons at a time.

    The benefit of the Bodac compared to a button matrix with diodes is a simpler wiring: a resistance between each button pin, and a single wire between each button. The optional cable incorporates the common resistance at the connector level, allowing only 2 wires to come out of the board.

    This pack of 1% precision resistors allows to create a Bodac with 5 buttons or less.

     

    WARNING : We don't provide any source code to use this product, we recommend to use NodeBlue which proposes a dedicated module.
