Design a Custom BoardAbout This Component
8-bit AVR microcontroller with 2KB in-system programmable flash memory, 128 bytes SRAM, and 12 programmable I/O lines. Features dual timer/counters with PWM, 10-bit ADC with 8 channels, SPI/TWI serial interfaces, and on-chip oscillator. Operates from 1.8–5.5V with configurable speed grades up to 12MHz and low-power modes for battery applications.
Package: TSSOP-20 (4.4×6.5mm) · 20 pins
Why does this need a breakout?
Hand-soldering 0.65mm pitch leads is tedious and error-prone; a breakout board with standard 0.1" headers lets you prototype I/O expanders and logic gates on breadboards without a reflow oven. The compact SSOP package also becomes DIP-friendly, eliminating jumper spaghetti and reducing assembly mistakes during development cycles.
