Micro USB LilyPad ATtiny85 Development Board

Ultra-Compact ATtiny85 Core: Powered by an 8-bit AVR ATtiny85 microcontroller running at 16.5MHz with 8KB Flash memory and 512 B SRAM for ultra-lightweight wearable projects.

Direct Micro-USB Programming: Integrated Micro-USB port allows direct code uploading, debugging, and power supply without needing an external FTDI programmer or USB breakout module.

E-Textile & Wearable Form Factor: Features a classic circular 25mm LilyPad layout with large, smooth petalled solder pads designed for easy sewing with conductive thread into clothing and accessories.

Onboard Power Regulator & Status LED: Built-in 5V voltage regulator handles external battery inputs up to 12V DC alongside onboard power and pin test LEDs.

Arduino IDE & Micronucleus Compatible: Supports programming via the Arduino IDE using the Micronucleus bootloader, offering full access to standard GPIO, PWM, I2C, SPI, and ADC channels.

Module Construction: Built on a compact 0.8 mm FR-4 glass epoxy printed circuit board featuring smooth gold-plated sewable pads and high-density surface-mount components.

Power Supply & Operating Voltage: Operates logic circuitry on 5V DC supplied via Micro-USB or 5V–12V DC external battery connections.

Washing & Maintenance: Ensure all batteries and power sources are fully disconnected before cleaning. Hand-wash fabric projects gently in cold water with mild soap and allow to air-dry for at least 48 hours before powering on again.

Handling Precautions: Observe standard ESD (electrostatic discharge) safety practices. Handle by the PCB edges with dry hands and double-check battery polarity when connecting external power.

Miniature Wearable Powerhouse: Position as the ultimate coin-sized microcontroller for subtle wearable tech, illuminated clothing, mini cosplay props, and soft robotics.

Seamless USB Plug-and-Play Setup: Highlight the onboard Micro-USB interface that allows beginners to upload code directly from a laptop without purchasing additional programming hardware.

Recommended Cross-Sell Add-ons: Pair with Conductive Thread Bobbins, LilyPad LED Modules, 3.7V/5V LiPo Power Modules, and Micro-USB Cables.

Ideal for Compact E-Textiles: Perfect entry-level choice for wearable LED jewelry, glowing costume accents, smart patches, and subtle touch-activated fashion items.
