An easy-to-use, open source capacitive sensing board

This project is coming soon. Sign up to receive updates and be notified when this project launches.

As the name suggests, HwUi is a hardware user interface made of capacitive touch sensors. It’s perfect for rapid prototyping or incorporating into your own projects in need of a user interface. The capacitive sensing works well even from behind many common plastics, such as acrylic, allowing you to remove the clutter of switches, drilling and wiring.

Hardware Features

  1. Capacitive inputs:
    • buttons
    • radial slider
    • linear slider
    • proximity sensor
  2. Microcontroller: STM32F030K6
  3. Capacitive sensing controller: CY8CMBR3106S
  4. Bluetooth module: BT53 or Beken BK3254
  5. Buses: I2C, UART, SPI
  6. I/O: ADC, GPIO

Open Source

The hardware, firmware, and software will all be open source.

HwUI’s Python-based GUI works with serial and Bluetooth interfaces to help automation engineers develop their own PC GUI for logging data and other controls.
