LilyPad 328 Main Board

ATmega328P Microcontroller Core: Driven by an 8-bit ATmega328P processor running at 8MHz with 32KB Flash memory, 2KB SRAM, and 1KB EEPROM for lightweight wearable computing.

Designed for E-Textiles & Wearables: Features a distinct flat, circular PCB layout (50mm diameter) with large, smooth solder pads tailored for stitching with conductive thread or soft wiring.

Low-Power 3.3V Logic Operation: Operates natively at 3.3V DC, making it safe and compatible with wearable lithium-polymer (LiPo) batteries and low-voltage sensors.

FTDI Programming Header: Includes an integrated 6-pin FTDI header for easy programming and serial communication using standard FTDI USB-to-serial adapters.

Washable Board Construction: Specially constructed for fabric projects—when unpowered, projects made with the board can be gently hand-washed.

Module Construction: Built on a thin, flexible 0.8mm FR-4 glass epoxy printed circuit board with wide petalled conductive pads and rounded, smooth edges.

Power Supply & Operating Voltage: Accepts power inputs ranging from 2.7V to 5.5V DC (recommended nominal operating voltage is 3.3V DC).

Washing & Maintenance: Ensure all batteries and power sources are removed before washing. Hand-wash gently in cold water with mild soap and allow to dry completely for at least 48 hours before reconnecting power.

Handling Precautions: Avoid sharp bends or mechanical stress on stitched connections. Handle with dry hands to prevent static discharge onto exposed components.

The Heart of Wearable Technology: Position as the core control unit for e-textile projects, smart clothing, wearable LED fashion, and soft robotics.

Designed for Conductive Thread: Highlight how the large, smooth connection pads prevent thread tearing, making circuit creation as simple as sewing.

Recommended Cross-Sell Add-ons: Pair with Conductive Thread Bobbins, LilyPad LEDs, FTDI Basic Programmer Breakouts, and 3.7V LiPo Batteries.

Ideal for Creative STEM & Textile Arts: Perfect entry-level board for art students, fashion designers, and makers combining craft work with microelectronics.
