-## Universal Hex Creator

-We have created a [Universal Hex Creator](../universal-hex-creator) tool, to easily create a .hex file that will support all micro:bit variants.

 ### Cross device compatibility
 
 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.
