Design a Custom BoardAbout This Component
ATtiny3227 is a 24-pin microcontroller from Microchip's tinyAVR 2 family featuring an 8-bit AVR CPU with hardware multiplier running at up to 20 MHz. It includes 32 KB Flash memory, 3 KB SRAM, 256 bytes EEPROM, and 22 GPIO pins across three ports. The device integrates a 12-bit differential ADC with programmable gain amplifier, event system, and advanced peripherals suitable for embedded control and IoT applications.
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.
