{"title":"A-Star 32U4 Micro","handle":"a-star-32u4-micro","url":"/products/a-star-32u4-micro","description":"The Pololu A-Star 32U4 Micro is a general-purpose programmable module based on the ATmega32U4 AVR microcontroller from Microchip. It packs 32 KB of flash, 2.5 KB of RAM, and built-in USB into a tiny 1″ × 0.6″ DIP package — even smaller than competing ATmega32U4 boards like the Teensy 2.0 and Pro Micro.\n\nIts 0.1″ pin spacing makes the A-Star easy to use with solderless breadboards, perfboards, and standard connectors. A voltage regulator and power selection circuit allow it to run from USB or an external 5.5–15 V source.\n\nKey Features\n\n\nATmega32U4 MCU – 32 KB flash, 2.5 KB RAM, built-in USB\n\n16 MHz Resonator – Stable clock source\n\n15 GPIO Pins – Including 7 PWM outputs and 8 analogue inputs; 3 more via ISP header\n\nUSB Micro-B – For programming and power\n\nFlexible Power – USB or external 5.5–15 V with reverse protection\n\nPTC Fuse – Resettable fuse on USB VBUS for accidental damage protection\n\nCompact – Only 1″ × 0.6″ in a 20-pin DIP form factor\n\nISP Header – 6-pin header for in-system programming\n\nIndicator LEDs – Two onboard status LEDs\n\n\nResources\n\nA-Star 32U4 User's Guide\n\n\nPackage Contents\n\n1× A-Star 32U4 Micro\n","vendor":"Pololu","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":12803,"title":"Default Title","sku":"PL-3101","price":19.0,"compare_at_price":30.91,"on_sale":true,"in_stock":true,"available_quantity":4,"option1":"Default Title"}]}
