Universal Hex Creator

Create a Universal Hex file

The Universal Hex Creator lets you combine a hex file created for a micro:bit V1 device and a hex file created for a V2 device, resulting in a Universal Hex format that is compatible with all revisions of the micro:bit.

DAPLink will process the Universal Hex and only write data to the relevant board revision; V1 or V2. More information is available on our Hex format, the Javascript/Typescript libary on which the Universal Hex Creator tool is based and the associated Universal Hex specification.

To support cross-device compatibility, we have created a standalone error hex that can be combined with a V2 only hex in this tool to produce a Hex that will work on a V2 board, but error if used on a V1.
