Design a Custom BoardAbout This Component
ATtiny 8-bit microcontroller with AVR core running up to 20 MHz, featuring 32 KB Flash, 2 KB SRAM, and 256 bytes EEPROM. Includes rich peripherals: dual 10-bit ADCs, three DACs, USART, SPI, TWI, multiple timers, real-time counter, and integrated Peripheral Touch Controller for capacitive sensing. Suitable for embedded control, IoT applications, and capacitive touch interfaces.
Package: HVQFN-24-1EP (4×4mm, EP) · 24 pins
Why does this need a breakout?
This 0.5mm pitch QFN-24 package requires a breakout board to prototype effectively — hand soldering the fine-pitch pads is impractical, and the bottom-side exposed pad cannot be accessed on breadboards. A breakout routes the 24 pins to standard headers, enabling rapid testing of multi-channel DACs, ADCs, VCOs, and other analog signal processors without reflow equipment.
