Design a Custom BoardAbout This Component
ATtiny427 is an 8-bit AVR microcontroller from the tinyAVR 2 family featuring 4KB Flash memory, 512B SRAM, and 128B EEPROM. Running at up to 20 MHz with a hardware multiplier, it includes a 12-bit differential ADC with programmable gain amplifier, Event System, and advanced digital peripherals. Ideal for embedded control applications requiring low power consumption in a compact 24-pin VQFN 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.
