Design a Custom BoardAbout This Component
ATtiny3216 is an 8-bit AVR microcontroller with 32 KB Flash, 2 KB SRAM, and 256 bytes EEPROM, running up to 20 MHz. Features integrated analog (two 10-bit ADCs, three DACs, three comparators), multiple timers, USART, SPI, TWI, and Peripheral Touch Controller for capacitive sensing. Suitable for embedded control, IoT, sensor interfaces, and capacitive touch applications.
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.
