SPOKE-mini - DIY Capacitive Touch Kit

by VulpesLabs

All the touch-sensing magic of SPOKE, in a small, embeddable board that you solder yourself.

SPOKE-mini turns a Raspberry Pi Pico into a 26-input capacitive touch controller. It's designed to be embedded inside projects, tucked behind an instrument, hidden in an installation, sewn into a costume, anywhere you want the sensing but not the visible PCB.

The kit is a great beginner soldering project: pop the 26 resistors into their labelled spots, solder in the Pico, flash CircuitPython, drop in the example code, and you're away. From kit to working controller in an afternoon.

Like SPOKE, it connects to any computer as a USB device and can control music, video, games, or any application via MIDI, keyboard mappings, or serial.

Kit includes

  • SPOKE-mini PCB
  • Raspberry Pi Pico H
  • 26 × 1MΩ resistors (plus a few spares)

A micro-USB cable is not included in the kit, but if you need one then we sell them separately.

Features

  • Powered by Raspberry Pi Pico
  • 26 capacitive touch inputs
  • Runs CircuitPython
  • USB-MIDI by default; also supports HID keyboard/mouse, OSC, and Serial
  • Open-source hardware and firmware
  • Compact footprint — designed for embedding
