Quick answer
The TinyLily 1206 LED includes a built-in current limiting resistor, so you can wire it directly to a TinyLily Mini or battery pack without external components—just mind the polarity.
Why the built-in resistor matters
Unlike a bare LED, the TinyLily 1206 LED has a current limiting resistor already soldered onto the board. This means you can connect it to a 3.3V or 5V supply without worrying about adding your own resistor or damaging the LED. It simplifies wearable projects where space is tight.
Polarity and sewtabs
The LED has two standard TinyLily sewtabs. The positive tab (anode) is usually marked with a plus sign or a small dot on the board. Reversing the connections won't damage the LED—it simply won't light up. If you don't see light, swap the wires.
Frequently asked questions
How do I wire the TinyLily 1206 LED to a TinyLily Mini?
Sew or solder the positive sewtab of the LED to any 3.3V or 5V output pin on the TinyLily Mini, and the negative sewtab to a GND pin. The built-in resistor handles current limiting.
What power supply works with the TinyLily 1206 LED?
A 3.3V or 5V regulated supply, such as a TinyLily Power Adaptor Board with a LiPo battery, works perfectly. The LED's built-in resistor is rated for those voltages.
Do I need an external resistor for the TinyLily 1206 LED?
No. The board includes a current limiting resistor. You can connect it directly to a power source without any additional components. Always check polarity first; if the LED doesn't light, swap the connections.
Can I use the TinyLily 1206 LED with a higher voltage?
The built-in resistor is designed for 3.3V–5V operation. Using a higher voltage may damage the LED. Stick to the recommended voltage range.
