Get started with Adafruit GEMMA with this lovely starter kit! Included is everything you need to make a basic project. There's a GEMMA board, four sewable bright RGB pixels, a battery holder (batteries not included,) 2-ply conductive thread, alligator clips to help you test out your circuit, and a USB cable for programming GEMMA.

• A microcontroller board small enough to fit into any project
• Low cost enough to use without hesitation
• It's our lowest-cost sewable controller!
• 6 Solderable Points
• Super small, only 1.1"
• Easy-to-sew or solder pads for embedding in your wearable project
• Low cost enough, you can use one for every weekend project
• ATtiny85 on-board, 8K of flash, 512 byte of SRAM, 512 bytes of EEPROM
• Internal oscillator runs at 8MHz
• Ultra low power, draws only 9 mA while running
• USB bootloader with a nice LED indicator looks just like a USBtinyISP so you can program it with the Arduino IDE
• Mini-USB jack for power and
• ~5.25K bytes available for use (2.75K taken for the bootloader)
• On-board 3.3V power regulator with 150mA output capability and ultra-low dropout
• Power with either USB or external output (such as a battery) - it'll automatically switch over
• On-board green power LED and red pin #1 LED
• Reset button for entering the bootloader or restarting the program.
• 3 GPIO - The 3 independent IO pins have 1 analog input and 2 PWM output as well.
