Design a Custom BoardAbout This Component
ATtiny84A is a low-power 8-bit AVR microcontroller with 8KB Flash, 512B SRAM, and 512B EEPROM in a 14-pin SOIC package. Features include 12 programmable I/O lines, 10-bit ADC with 8 single-ended and 12 differential channels, dual timers with PWM, watchdog timer, and debugWIRE on-chip debugging. Operates from 1.8–5.5V with ultralow power modes (0.1µA power-down), ideal for battery-powered embedded systems, sensors, and IoT applications.
Package: SOIC-14 (3.9×8.7mm) · 14 pins
Why does this need a breakout?
Manual soldering of 1.27mm pitch SOIC-14 leads is tedious and error-prone; a breakout board eliminates this with pre-soldered pads and convenient 0.1-inch headers for breadboard prototyping. Ideal for developing capacitive touch sensor applications or other logic circuits without the fine-pitch assembly hassle.
