Design a Custom BoardAbout This Component
8-bit AVR RISC microcontroller with 2KB in-system programmable flash, 128B EEPROM, and 128B SRAM. Features 18 I/O lines, dual timers with PWM, USART, SPI, and on-chip debugging. Operates at up to 20 MHz across 2.7–5.5V supply range with low power idle modes. Suitable for embedded control, IoT, and sensor applications.
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.
