Peptide's ATtiny85-Based Arduino-Compatible Touch Board Is a Compact USB Type-C Input Gadget

Featuring an integrated touch sensor and a red/green bi-color LED, this compact board could be handy for simple interaction projects.

Pseudonymous maker "Peptide" has released what they claim is the "smallest" Arduino-compatible development board to feature a USB Type-C connector and an integrated touch sensor — created using a Microchip ATtiny85 microcontroller.

"This is the smallest USB-C Arduino[-compatible] board with an ATtiny85 chip, a touch sensor, and a LED on it," Peptide writes of their creation. "The touch sensor can work even with a thin enclosure. There is a LED light which you can use to indicate different status. You can program it to respond to single touch, double touch, or even triple touch for different actions."

The unnamed board is not, of course, a true Arduino — but its use of an ATtiny85 microcontroller means it's compatible with the Arduino IDE and PlatformIO. Those looking to wire it up to external hardware, however, may be disappointed: The board's compact layout means it lacks easily-accessible general-purpose input/output (GPIO) pins, instead focusing on projects that use its capacitive touch sensor and on-board bi-color red/green LED.

Peptide has not released design files for the board, but is selling assembled versions on Tindie at $24.99 each.
