Design a Custom BoardAbout This Component
AVR 8-bit microcontroller with 2KB in-system programmable flash, 128 bytes EEPROM, and 128 bytes SRAM. Features 10-bit ADC with 11 single-ended and 16 differential channels, PWM outputs, watchdog timer, and debugWIRE interface. Operates from 1.8-5.5V with maximum 20 MHz clock speed and ultra-low power modes.
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.
