Summary of The Arduino Gemma
The Arduino Gemma is a compact wearable board featuring an ATtiny85 processor, designed for easy programming via USB using the Arduino IDE. Developed in collaboration with Adafruit Industries, this 27 mm diameter board offers 8K flash memory and 5 I/O pins, two of which are used by the USB bootloader, leaving three pins available for user projects. It is tailored for small, simple wearable projects, especially those incorporating conductive thread.
Parts used in the Arduino Gemma:
- ATtiny85 microcontroller
- Micro USB connector
- PCB (27 mm diameter wearable board)
- USB bootloader (pre-installed on ATtiny85)
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,
