This handy adapter has a female 2.1mm barrel jack socket on one end and a male Micro-USB connector on the other, ideal for powering your Raspberry Pi Zero from a 5V 2.1mm DC power supply. This adapter will pass whatever voltage you put into the barrel jack end, so when using with a Raspberry Pi you MUST ensure it's a well-regulated 5V power supply. The barrel jack has a centre-positive tip. You can of course use it for any other device that uses a Micro-USB connection too! https://elecena.pl/product/22712615/straight-micro-usb-to-2-1mm-barrel-jack-adapter 2023-03-06 https://elecena.pl/product/22712615/straight-micro-usb-to-2-1mm-barrel-jack-adapter 2023-12-27 https://elecena.pl/product/22712615/straight-micro-usb-to-2-1mm-barrel-jack-adapter 2024-09-19 https://elecena.pl/product/22712615/straight-micro-usb-to-2-1mm-barrel-jack-adapter 2024-11-29 https://elecena.pl/product/22712615/straight-micro-usb-to-2-1mm-barrel-jack-adapter 2024-11-30 https://elecena.pl/product/22712615/straight-micro-usb-to-2-1mm-barrel-jack-adapter 2025-11-28 https://elecena.pl/product/22712615/straight-micro-usb-to-2-1mm-barrel-jack-adapter 2025-11-29
