Design a Custom BoardAbout This Component
8-bit AVR microcontroller with 4KB in-system programmable flash memory, 256 bytes EEPROM, and 256 bytes SRAM. Features 10-bit ADC with 16 differential channel pairs, 3 PWM outputs, timer/counters, and Universal Serial Interface. Operates 2.7–5.5V at up to 10 MHz with debugWIRE on-chip debugging and low-power modes for embedded 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.
