The dataPad is a USB device, it uses a Raspberry pi Pico microcontroller, a 1 inch 128x64 oled screen, an analog joystick, 21 buttons corresponding to 21 addressable RGB leds for feedback. It can be used to control any kind of software. In this case I use it to easily work with Rhino3D for 3D modeling, the "driver" (serial communication between the device and the PC) is created using Python3 and can be found in the Driver directory. The .stl files for 3D printing will be added soon with the schematic to an hardware-dedicated directory.
