Design a Custom BoardAbout This Component
Automotive-grade 8-bit microcontroller based on AVR architecture with 4KB Flash memory, 256 bytes SRAM, and 128 bytes EEPROM. Runs up to 16 MHz with integrated peripherals including USART, SPI, I2C, 10-bit ADC, timers, and watchdog. Features flexible sleep modes, brown-out detection, and UPDI programming interface for embedded control applications.
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.
