ATmega32U4 LilyPad USB microcontroller Board

Built-In USB Functionality: Powered by the ATmega32U4 microcontroller with native USB support, eliminating the need for a separate FTDI adapter or external USB-to-serial converter board.

Direct Micro-USB Programming: Features an onboard Micro-USB port for straightforward code uploading, power delivery, and direct USB HID (mouse/keyboard) emulation.

Tailored for E-Textiles & Wearables: Flat circular board layout (50mm diameter) with large, smooth solder pads designed specifically for sewing with conductive thread into clothing and fabrics.

Low-Power 3.3V Logic Architecture: Runs natively on 3.3V DC logic at 8MHz (32KB Flash memory, 2.5KB SRAM), making it safely compatible with rechargeable LiPo batteries and low-voltage sensors.

Integrated LiPo Battery Charging Circuit: Includes an onboard 3.7V lithium-polymer battery charging IC, allowing automatic battery charging directly via the Micro-USB port connection.

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

Power Supply & Operating Voltage: Accepts power directly via the Micro-USB cable (5V DC) or an external 3.7V LiPo battery connected to the onboard battery power terminals.

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 let air-dry for at least 48 hours before powering on again.

Handling Precautions: Observe standard ESD (electrostatic discharge) safety precautions. Handle by the PCB edges with dry hands and ensure correct battery polarity when attaching external LiPo cells.

All-in-One Wearable Controller: Position as the ultimate step-up board for LilyPad users, combining processing power, built-in USB uploading, and LiPo battery charging on a single compact board.

Emulates USB Peripherals: Highlight its ability to act as a native USB Human Interface Device (HID), enabling creative wearable game controllers, smart wristbands, and soft macro pads.

Recommended Cross-Sell Add-ons: Pair with Conductive Thread Bobbins, LilyPad LED Breakouts, 3.7V Rechargeable LiPo Batteries, and Micro-USB Programming Cables.

Ideal for Interactive Smart Apparel: Perfect platform for fashion technology projects, cosplay costumes, wearable light shows, and mobile e-textile prototyping.
