Design a Custom BoardAbout This Component
8-bit AVR microcontroller with 2KB in-system programmable flash, 128 bytes SRAM, and operating range of 1.8–5.5V. Features dual 8-bit and 16-bit timers with PWM, 10-bit ADC with 8 channels, SPI/TWI interfaces, and programmable watchdog timer. Ideal for embedded control applications requiring low power consumption and minimal pin count.
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.
