ALLNET 4duino základná doska pre Lilypad (ALL_OY_2021)

The ALLNET 4duino Mainboard for Lilypad (ALL_OY_2021) is a compact, round, sewable microcontroller board designed for wearable electronics and e-textile projects. Based on the ATmega328P microcontroller, it operates at 5V with a clock speed of 16 MHz, offering 14 digital I/O pins (6 PWM), 6 analog inputs, 32 KB flash memory, 2 KB SRAM, and 1 KB EEPROM. The board features sew tabs for conductive thread, a JST connector for LiPo battery or external 2.7-5.5V supply, and indicator LEDs for power, TX, and RX. It is compatible with the Arduino IDE and comes pre-installed with the Arduino LilyPad bootloader. Ideal for smart garments, DIY projects, and interactive wearables.

Advantages
