Design a Custom BoardAbout This Component
8-bit AVR microcontroller with 16KB flash program memory, 256B EEPROM, and 1KB SRAM. Features 18 I/O pins, dual UARTs, 12-channel 10-bit ADC, dual timers with PWM, I2C interface, and capacitive touch sensing support. Operates at 1.8–5.5V with ultra-low power modes (100nA standby) and internal oscillators; suitable for embedded control and IoT 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.
