Design a Custom BoardAbout This Component
Atmel ATtiny4 is a low-power 8-bit AVR microcontroller with 512 bytes flash memory, 32 bytes SRAM, and 4 programmable I/O lines. Operating from 1.8–5.5V with throughput up to 12 MIPS, it features a 16-bit timer, PWM channels, ADC, and watchdog timer. Ideal for cost-sensitive embedded applications requiring minimal power consumption and compact footprint.
Package: SOT-23-6 · 6 pins
Why does this need a breakout?
SOT-23-6 packages house precision regulators, voltage references, and level shifters with 0.95mm pin pitch—too fine for hand soldering and incompatible with breadboards. A breakout board provides through-hole headers for prototype work, eliminating soldering difficulty while enabling quick circuit iteration. Essential for developing with compact analog and power management ICs.
