Beetle-A Small Microcontroller for Arduino Leonardo with USB HID for IoT & Wearable Projects (20mm×22mm, ATmega32u4, 3V Battery Support)

Beetle-A Small Microcontroller for Arduino Leonardo with USB HID for IoT & Wearable Projects (20mm×22mm, ATmega32u4, 3V Battery Support)

• Ultra-Compact Design: 20mm×22mm 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

The new generation" beetle" controller derives its core notion from minimalism without compromising functionality. It comes with atmel atmega32u4 @16MHz clock time and has expanded amounts of interfaces: 10 digital pins, 5 analog pins and 4 PWM pins. To further make it user-friendly, it is compatible with Micro USB so that direct programming and testing is no longer a headache. Select" arduino leonardo (tools > board > arduino leonardo in arduino ide), the atmega32u4 comes pre-burned with a bootloader that allows you to upload any new Code that is applicable to arduino leonardo.
