Product details

The GEMMA v2 development board from Adafruit is a compact and powerful platform specifically designed for wearable projects. With a diameter of just 1 inch (28 mm) and a thickness of 0.28 inches (7 mm), it is the ideal microcontroller board for creative applications where space is limited. Powered by an ATtiny85 microcontroller, the board offers 8 KB of flash memory, 512 bytes of SRAM, and 512 bytes of EEPROM, making it a flexible solution for various projects. Programming is done via the Arduino IDE, which makes it easy to get started, even though it is not fully Arduino-compatible. Its ultra-low power consumption of only 9 mA in operation makes it particularly attractive for wearable applications. With easy-to-solder pads and a micro USB port for power and data transfer, the GEMMA v2 is an affordable and practical choice for anyone looking to develop innovative wearable technologies.

  • Compact design with only 28 mm diameter
  • Easy integration through solderable pads
  • Cost-effective for numerous projects
  • ATtiny85 microcontroller with 8K flash memory
  • Ultra-low power consumption of only 9 mA in operation.
