Design a Custom BoardThe ATtiny3227 is a tinyAVR 2 family microcontroller featuring an 8-bit AVR CPU with hardware multiplier running at up to 20 MHz. It integrates 32 KB Flash memory, 3 KB SRAM, and 256 bytes of EEPROM in a 24-pin VQFN package. The device includes 22 GPIO pins, a 12-bit differential ADC with programmable gain amplifier, event system, and advanced digital peripherals for embedded control applications.
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.
