This is the documentation for the micro:bit Universal Hex library.

Originally the micro:bit hex files used the Intel Hex format and with the micro:bit V2 release a new hex format was created to be able to flash any micro:bit board version with a single file.

The Universal Hex file format can contain the binary data for multiple micro:bit board versions and this TypeScript/JavaScript library can be used to create a micro:bit Universal Hex from two or more micro:bit Intel Hex files.
