TinyLily Mini Processor

SKU: ASM2101


The TinyCircuits TinyLily Mini is an Arduino compatible module in an ultra compact package. Designed to be used in e-textile and wearable applications, the TinyLily Mini is very similar to the Arduino LilyPad with the same processing power and Arduino software compatibility – but at 1/12th the size!
  • Arduino and LilyPad Compatible
  • Atmel Atmega328P processor (same as is used on the Arduino Uno and LilyPad)
  • Washable
  • Sewtabs for 8 I/O (4 Digital, 4 Analog / Digital) and 4 Power Sewtabs (2 for power, 2 for ground)
Note: To program this board, you need to use the TinyLily Mini USB Boardwhich is sold separately. 


    • Arduino and LilyPad Compatible
    • Washable
    • Robust Gold Finish – makes soldering easy and is non-corrosive
    • Sewtabs for 8 I/O (4 Digital, 4 Analog / Digital) and 4 Power Sewtabs (2 for power, 2 for ground)
    • Sewtabs are 1.2mm in diameter, easy to use with standard conductive thread and needles
    • Arduino Bootloader preprogrammed (uses approx 0.5 KBytes of Flash Memory)
    • USB expansion header (for use with the TinyLily Mini USB Board)
    • Ultra compact size and weight (smaller than a US Dime!)
      • 14.0mm (0.55 inch) diameter
      • Max Height: 2.8mm (0.11 inches)
      • Ultra-thin 0.61mm (0.024 inches) PCB
      • Weight: .39 grams (.01 ounces)
    • Atmel ATmega328P Microcontroller
      • 32KB Flash, 2KB RAM, 1KB EEPROM
      • 1.2mA (typical) @ 3V, 4MHz
      • Clock speed: 8MHz
    • 2.7V – 5.5V operating voltage  


      • If you are brand new to the TinyLily, buying a kit is the best way to go since it will have all the parts needed.  Check out the kits here.
      • This board does not include a voltage regulator – do not supply more than +5.5V or you will permanently damage the board and ruin your day. 
      • The back of the board has signals for SPI programming of the unit, and it is possible to solder wires to these pads to get access to the SPI signals if needed in your application. The picture below shows the signal assignments for this:
