 The Universal Hex format has been developed to ensure the best experience for users when moving between board variants. If a V1 only .hex is detected on a V2 board it will throw an error, but a V2 only hex will fail silently on a V1. This is very confusing to users and should be avoided.

+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](../hex-format) page and the [Javascript/Typescript libary](https://github.com/microbit-foundation/microbit-universal-hex) on which the Universal Hex Creator tool is based.
