Beetle-A Small Microcontroller for Arduino Leonardo with USB HID for IoT & Wearable Projects (20mmx22mm, ATmega32u4, 3V Battery Support)

Features

• Ultra-Compact Design: 20mmx22mm thumb-sized design is ideal for wearables and embedded systems, featuring wide-spaced pads for seamless conductive sewing and textile integration.
• No-Solder, Sewable Design – V-shaped gold-plated pads let users twist wires or stitch directly onto fabric with conductive thread. Ideal for beginners, classrooms, and rapid prototyping–no soldering iron needed.
• Plug-and-Play with Arduino IDE – Program via Micro USB. Leverage Leonardo’s USB-HID to create keyboards, mice, or game controllers. Directly download and debug programs via Micro USB interface, no need for programmer
• Low-Power & Expandable: 10 digital pins + 5 analog inputs with 3V coin battery support | Optimized for long-term wearable use, compatible with SPI/I2C expansion via minimal wiring
