Design a Custom BoardAbout This Component
The ATtiny3217 is a low-power 8-bit AVR microcontroller featuring 32 KB Flash, 2 KB SRAM, and 256 bytes EEPROM, running at up to 20 MHz. It integrates multiple peripherals including timers, USART, SPI, TWI (I2C up to 1 MHz), dual 10-bit ADCs, DACs, and a Peripheral Touch Controller for capacitive sensing. Ideal for embedded applications requiring flexible analog features, touch interfaces, and event-driven processing in a compact 24-pin package.
Package: QFN-24 (4×4mm) · 24 pins
Why does this need a breakout?
This 0.5mm pitch QFN is nearly impossible to hand solder and entirely incompatible with breadboards due to hidden pads beneath the package. A breakout board provides accessible headers and pre-soldered connections, letting you prototype with InvenSense motion sensors via I2C or SPI without specialized SMD equipment or rework skills.
