Design a Custom BoardAbout This Component
8-bit AVR RISC microcontroller with 4KB in-system programmable flash and 256 bytes EEPROM. Features 18 I/O lines, dual timer/counters with PWM, USART, and SPI interfaces. Operates from 1.8–5.5V with up to 20 MHz clock speed and integrated oscillator. Suitable for embedded control applications requiring low power consumption and compact form factor.
Package: SOIC-20W (7.5mm wide) · 20 pins
Why does this need a breakout?
The 1.27mm pin pitch makes hand-soldering this 20-pin SOIC challenging and error-prone. A breakout board brings all pins to standard 0.1" spacing, enabling reliable breadboard prototyping and simplifying development of USB-to-UART interfaces without requiring reflow soldering or specialized equipment.
