Summary of The Arduino Gemma
Massimo Banzi previewed the Gemma, a 27mm wearable Arduino board developed with Adafruit Industries. Featuring an ATtiny85 processor, it supports programming via the Arduino IDE and USB bootloader. The board offers 8K flash memory and five I/O pins, including analog inputs and PWM outputs. Two pins are reserved for USB communication, leaving three available for projects like those sewn with conductive thread.
Parts used in the Arduino Gemma:
- Gemma wearable Arduino board
- ATtiny85 processor
- Micro USB connector
- Conductive thread
In a presentation at the Maker Faire held in Rome this weekend Arduino co-founder Massimo Banzi gave a preview of the soon to be released Gemma wearable Arduino board. The 27 mm diameter board contains an ATtiny85 processor programmable from the Arduino IDE via Gemma’s micro USB connector. The design is a collaborative effort together with Adafruit Industries who also worked on the Arduino Micro.
The ATtiny85 has 8K of flash and 5 I/O pins, including analog inputs and PWM outputs. It was designed with a USB bootloader so you can plug it into any computer and reprogram it over a USB port (it uses 2 of the 5 I/O pins, leaving you with 3). Ideal for small & simple projects sewn with conductive thread,
