Design a Custom BoardAbout This Component
ATtiny25 is a low-power 8-bit AVR microcontroller with 2KB in-system programmable flash, 128B SRAM, and 128B EEPROM. Features include a 10-bit ADC with 4 single-ended and 2 differential channels, two 8-bit timers with PWM, USI serial interface, and internal oscillator. Operates from 2.7-5.5V at speeds up to 20MHz, suitable for cost-sensitive embedded applications requiring minimal I/O.
Package: SOIC-8 (3.9×4.9mm) · 8 pins
Why does this need a breakout?
An 8-pin SOIC with 1.27mm pitch is too fine for breadboards and hand-soldering without a microscope. A breakout board routes these pins to standard 0.1" headers, enabling rapid prototyping and reliable connections for op-amps, transceivers, and small power MOSFETs without requiring reflow equipment.
