About this item

The ATTiny85 is a compact and efficient 8-pin microcontroller from Atmel's AVR 8-bit family, ideal for simple and space-constrained embedded applications. Despite its small size, it packs enough functionality for a wide range of basic electronic and IoT projects. It operates at frequencies up to 20 MHz, providing sufficient processing power for tasks like sensor data reading, LED control, or communication with other devices. The microcontroller features 8KB of Flash memory, 512 bytes of EEPROM, and 6 I/O pins, allowing for versatile hardware interfacing. It also includes a 4-channel 10-bit ADC, enabling the connection of analog sensors and voltage measurement devices. A single 8-bit timer and support for external interrupts further enhance its utility in time-critical applications. One of the main reasons for the ATTiny85’s popularity is its ability to be programmed via the Arduino IDE, using tools like the USBasp or through Arduino as ISP. This makes it an excellent option for beginners and hobbyists looking for a low-cost, low-power solution that doesn’t sacrifice programmability or community support. With its compact form factor and efficient architecture, the ATTiny85 is widely used in wearables, miniaturized projects, and DIY electronics that require minimal components and low power consumption.
