Description:
The LilyTiny ATtiny85 LilyPad CJMCU Development Board – Arduino Compatible is a compact, sewable microcontroller board based on the ATtiny85 chip, designed for wearable electronics and lightweight interactive projects. Its small circular form factor and sew-through pads make it ideal for integrating into e-textile and fashion-tech designs, all while remaining fully programmable via the Arduino IDE using an external USB programmer.
Despite its tiny size, the board packs four pre-programmed I/O behaviours (blink, heartbeat, fade, and random fade) and supports custom programming for more advanced tasks. Operating at 8MHz and powered by 2.7V to 5.5V, it’s perfect for LED control, soft robotics, capacitive touch sensing, and simple logic tasks. As a member of the LilyPad ecosystem, it seamlessly fits into conductive thread circuits, DIY smart garments, and embedded art installations.
