Design a Custom BoardAbout This Component
ATtiny426 is a 20-pin SOIC microcontroller from Microchip's tinyAVR 2 family featuring an 8-bit AVR CPU with hardware multiplier, 4KB Flash memory, 512B SRAM, and 128B EEPROM. Running at up to 20MHz, it includes a 12-bit differential ADC with programmable gain amplifier, Event System, and advanced digital peripherals. Suitable for low-power embedded applications requiring flexible I/O and analog capabilities.
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.
