Design a Custom BoardAbout This Component
ATtiny426 is a 20-pin 8-bit AVR microcontroller from Microchip's tinyAVR 2 family, featuring 4KB Flash memory, 512B SRAM, and 128B EEPROM. It runs at up to 20 MHz with integrated peripherals including a 12-bit ADC with PGA, Event System, and flexible low-power architecture. Ideal for embedded control applications requiring compact form factor and minimal power consumption.
Package: SSOP-20 (5.3×7.2mm) · 20 pins
Why does this need a breakout?
The 0.65mm pitch and narrow 5.3mm width make hand soldering this SSOP-20 extremely difficult without specialized equipment. A breakout board routes pins to standard 2.54mm headers, enabling breadboard prototyping and eliminating microscopic soldering. Ideal for evaluating microcontrollers and peripheral ICs during development.
