Design a Custom BoardAbout This Component
8-bit AVR microcontroller with 2KB flash, 128B SRAM, and 12 programmable I/O lines. Features dual timers with PWM, 10-bit ADC, SPI/TWI serial interfaces, and internal oscillator. Operates from 1.8–5.5V with ultra-low power modes (0.1µA standby), suitable for battery-powered embedded applications and IoT devices.
Package: TSSOP-14 (4.4×5mm) · 14 pins
Why does this need a breakout?
The 0.65mm pitch on this 14-pin package makes hand soldering tedious and error-prone without magnification and fine tools. A breakout board routes each pin to standard 0.1-inch headers, enabling breadboard prototyping and simplifying connections for LIN transceivers, ADCs, digital potentiometers, and microcontrollers that typically come in this footprint.
