The Raspberry Pi model 3 B+ (RPi 3 B+) is the latest available in the Raspberry Pi series, released in mid-March 2018. RPi 3 B+ has some nice features and improvements over the previous RPi 3 B. They include faster 1.4 GHz processor clock speed, Gigabit Ethernet speed, dual-band 2.4GHz and 5GHz wifi support, and Bluetooth 4.2.
Fedora 28 was released soon after the RPi 3 B+. The good news is it supports the RPi 3 B+, as well as the RPi Model B versions 2 and 3. Images are available to download for both ARMv7 (32-bit) and aarch64(64-bit). This article
