Design a Custom BoardAbout This Component
ATtiny817 is an 8-bit AVR microcontroller with 8KB Flash, 512B SRAM, and 128B EEPROM, running at up to 20MHz. It features integrated analog peripherals including 10-bit ADC, 8-bit DAC, and a Peripheral Touch Controller for capacitive sensing. The 24-pin QFN package includes USART, SPI, I2C, multiple timers, and an Event System for core-independent operation.
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.
