Quick Answer

Choose the TinyDuino Processor Board when you need Arduino compatibility and expandability; choose the TinyLily LED module when you want a simple, sewable LED for soft wearable projects.

Size and Form Factor

TinyDuino is an ultra-compact Arduino-compatible board, smaller than a quarter, making it ideal for projects where space is tight but you still need full Arduino power.

TinyLily modules are designed for e-textile projects, with sew tabs that let you stitch them directly into fabric, avoiding bulky connectors.

Compatibility and Ease of Use

TinyDuino runs most Arduino sketches without changes, so you can reuse existing code and libraries.

TinyLily LED modules include a built-in current limiting resistor, so you don't need to add external resistors or worry about burning out the LED.

Trade-offs at a Glance

  • Processing Power: TinyDuino offers full Arduino Uno-level processing, while TinyLily modules are simple components without processing capability. If your project needs logic, sensors, or control, TinyDuino is the board; TinyLily is for adding lights or simple outputs.
  • Ease of Integration: TinyLily modules sew directly into fabric with sew tabs, while TinyDuino requires a shield connector and wiring. For quick e-textile prototypes, TinyLily is easier; for complex wearable electronics, TinyDuino offers more flexibility.
  • Expandability: TinyDuino supports shields for adding sensors, displays, and communication; TinyLily modules are standalone components. If you plan to scale up your project, TinyDuino's shield ecosystem is a major advantage.

Product Facts

  • TinyDuino Processor Board (ASM2001-R) Rectangular without battery holder: The TinyDuino Processor Board is Arduino compatible and roughly equivalent to an Arduino Uno, with the same processor and signals brought out to a shield connector. You can use most existing Arduino sketches without modification, speeding up development for compact projects.
