Design a Custom BoardAbout This Component
ATtiny404 is an automotive-grade 8-bit microcontroller featuring a 16 MHz AVR CPU, 4 KB Flash memory, 256 bytes SRAM, and 128 bytes EEPROM. It includes integrated peripherals: USART, SPI, I2C, 16-bit timers, RTC, 10-bit ADC, and analog comparator. Operates from 2.7V to 5.5V with multiple low-power sleep modes and event system for autonomous inter-peripheral communication.
Package: SOIC-14 (3.9×8.7mm) · 14 pins
Why does this need a breakout?
Manual soldering of 1.27mm pitch SOIC-14 leads is tedious and error-prone; a breakout board eliminates this with pre-soldered pads and convenient 0.1-inch headers for breadboard prototyping. Ideal for developing capacitive touch sensor applications or other logic circuits without the fine-pitch assembly hassle.
