1.1. Supported operating systems

The A-Star 32U4 Robot Controller boards can be programmed using Microsoft Windows 10, 8.1, 8, 7, Vista, XP (with Service Pack 3), Linux, and macOS 10.11 or later.

Note: Although the A-Star 32U4 works on macOS 10.11 through 10.14, there is a bug in macOS 10.15 (Catalina) and later that makes it impossible to program the A-Star 32U4 using the bootloader we ship with the board. However, it is possible to use an AVR programmer (not included) to burn a new bootloader onto the board and get it working. For more details, please see our page about the macOS bug affecting the A-Star 32U4 Bootloader.
